Dr Peter FitzGerald: “Nothing will ever be the same again.”
Dr Peter FitzGerald: Nothing will ever be the same again.
An Interview with Ulster Business Editor John Mulgrew in The Belfast Telegraph, in which Dr FitzGerald speaks to John about developing and helping roll out millions of tests for Covid-19, a forever changed society, the high likelihood of a similar pandemic returning and when a vaccine for the virus could be found.
Dr Peter FitzGerald’s expertise and opinion has probably never been taken as seriously as it has in the last few months.
“Nothing will be the same again,” he tells Ulster Business. And, of course, he’s right.
His firm Randox – based in Antrim – has been on the front line of testing for Covid-19 right across the UK and beyond. And as a result, he’s hired hundreds of new staff and built a £30m testing lab to deal with additional deluge of work resulting from a global pandemic unlike anyone here has ever seen.
“I think there is a reasonable chance there will be more pandemics, with globalisation and increased population,” he told Ulster Business. “I have no idea how much it will come back again in second wave.
“We know we have the capacity as a company to respond, and respond well. I suspect the country is going to be better prepared… it’s hard to predict.”
The medical testing giant’s first involvement with the current coronavirus strain began back in January, before it became an increasingly concerning dinner conversation in homes across Northern Ireland.
“In late January, research called and were looking at doing a test,” Peter said. “We downloaded the genetic sequence of the virus and spent the next two weeks developing a test. We can do it very quickly, as we already had coronaviruses on chip.
“It was sent to Public Health England, which took a while to prove it. We then got a contract to test for the NHS… we were doing what we thought was for the national good.”
The initial deal didn’t include all of the UK, but Randox is now also testing Northern Ireland.
“We do the testing and we have different analysers that do the testing as well, which we sell to labs across the world.”
The virus has led to a new complete lab being built (in which Peter is pictured in) to deal with the additional testing. “We decided to accelerate the manufacturing in our Randox Science Park in Antrim,” he says.
As a result, it has hired around 200 staff in the space of six to eight weeks to deal with the surge.
“Because we had closely related strains of the virus, it was wasn’t so difficult to modify our tests to allow for slightly different variations… once we got the contract we soon realised that we didn’t have enough lab space to deal with the ramp up.
“We then decided to be 33,000 sq ft of new lab space, and it was needed in three weeks. We got that done – work was 24 hours a day, and seven days a week. It’s now operating well. That has been very important in the process.”
Randox had a workforce of around 1,450 worldwide before the coronavirus crisis began, but has since taken on around 280 additional staff for a range of roles, partly in ramping up demand for the additional testing.
“A lot were being taken on a temporary basis but many will be permanent. We are not sure of the final numbers, but well over 100.” Those roles include scientists, manufacturers, and engineers.
“Nothing will be the same again,” Peter says. “What it has done is heightened the importance of testing. People sometimes don’t know what we do here at Randox… but people now realise.
“In the end, it’s a good thing. We are advocates of testing. It identities disease before symptoms occur and can save lives in many occasions. It saves lives and saves costs. It fits in with what we have been trying to do for years… as far as we are concerned, it’s the silver lining.
“We have customers worldwide and other products kept going. We moved around 100 scientists into Covid-related things and then they have gone back to normal jobs as we bring in new people.
“Some of our R&D projects have changed, new systems and new analysers allow for efficient and accurate testing.”
Peter says that just a small element of the business has seen a decrease amid the crisis, while other areas around Covid-19 have grown. “Only a small element of core business decreased. But our Covid and other genetic products have increased… overall sales will be up and by end of year normal business up as well.”
As a result of the latest expansion and growth across the business, generally speaking, Peter says the workforce looks set to climb to 1,650, with around 500-600 based at its main headquarters, just outside Antrim.
Peter’s also keen to reiterate the importance of Northern Ireland and its people to Randox. “This is our home base. It’s where we do our primary R&D and manufacturing. We also have a facility in Donegal.”
And, could all of this happen again soon, with a further outbreak or a similarly devastating strain or pandemic?
“(We are) more prepared and our technology is getting more accepted through bio chips. Early detection is a very important next stage. You don’t want people who have a cough or fever to think they have Covid all the time. That is where testing comes in and that differentiates.”
Peter says the next stop forward in a bid to address similar future incidents it also understanding how our immune systems work – better.
“The other major step forward in many ways is understanding the immune system better. How to better respond to infection. This will be very important.
“Some people are susceptible, and this could be genetic. (It’s about) working on certain genes in those who may have a bad attack. It will prepare humans better, the body’s defence, dealing with it as well.
“I have a deficiency in a particular gene which means I’m more susceptible to respiratory (conditions) but the spin-off of the gene means I’m less susceptible to certain cancers. This is the issue – it is so complex. One could be a strength and one moment, a weakness.”
And as for the formulation of a proven vaccine, Peter says: “I would say it would be well into next year.”

More useful information
Creatinine is the end-product of muscle catabolism of creatine. In humans, creatinine production is relatively stable, but mainly depends on muscles mass. Consequently, any physiological changes in muscle mass will cause a variation in the creatinine pool independently of GFR changes. Creatinine is freely filtered by the glomerulus at a constant rate with 10% to 40% secreted by the tubules 1.
According to the National Institutes of health, the overall prevalence of chronic kidney disease (CKD) is approximately 14% 2. Creatinine is the most commonly utilised assay in the assessment of renal function 3. The National Kidney Disease Education Program recommends calculating GFR from SCr. Creatinine measurements are useful in the monitoring of disease progression, with the diagnosis of renal failure when SCr levels are greater than the upper normal interval 4.
Creatinine measurements are useful in the diagnosis and monitoring of diabetic nephropathy, the leading cause of kidney disease in patients commencing renal replacement therapy, affecting 40% of diabetics (type 1 and type 2) 5. The RENAAL (Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan) study risk score for end-stage renal disease (ESRD) emphasizes the importance of the identification of elevated SCr, alongside other renal markers, in the prediction of end-stage renal disease (ESRD) development in patients with type 2 diabetes mellitus (T2DM) and nephropathy 6.
Acute kidney injury (AKI) is a common complication in COVID-19 patients 7. The analysis of creatinine in COVID-19 patients on hospital admission and after 2 to 4 days highlighted impaired renal function and is the leading cause of death in these patients 8. The National Institute of Care Excellence (NICE), have set out four guidelines for acute kidney injury in hospitalised suspected or confirmed COVID-19 patients and highlights the importance of creatinine testing 9.

Update on Sample Kits
STATEMENT FROM RANDOX: 07 August 2020
Randox Laboratories have today taken the decision to recall Covid-19 sample collection kits, following the identification of incomplete EC certification. On 15th July DHSC placed these kits on hold due to the absence of swab certification from an external supplier. To date, Randox have not been provided with evidence to satisfactorily support the CE marking for these swabs. So, noting the lack of CE certification by the supplier and that some kits remain in the field at this time Randox has, as a regulatory measure, initiated the recall of those kits used within the National Testing Programme.
Randox Laboratories will continue to provide high volume Covid-19 testing to the National Testing Programme from their laboratories, based on sample collection kits from other providers.
DHSC have stated the risk to safety is low and test results from Randox kits are not affected.
This recall applies only to sample collection kits within the UK National Test and Trace Programme. Randox private customers or kits are not affected.

Bilirubin is a metabolite of haem, derived from haem-containing proteins, including myoglobin, haemoglobin and various P450 enzymes, that serves to coordinate iron in various proteins. Half of it is excreted into bile and the rest contributes to blood bilirubin turnover 1. It is mainly produced in the spleen and liver but can also occur elsewhere in the body by macrophages and renal tubular cells 2. The internal hydrogen bonding causes it to be water-insoluble and so required enzyme-mediated glucuronidation in the liver for biliary excretion. Under normal conditions, it is mostly unconjugated and bound tightly to albumin 3.
Bilirubin is one of the most common diagnostic tests utilised in the diagnosis and monitoring of hepatic dysfunction. It is impaired in cholestatic and parenchymal liver diseases. The most common condition associated with elevated levels is jaundice (a clinical sign of hyperbilirubinaemia), characterised by the yellow colouring of skin, mucous membranes and sclera 3.
Today, it is recognised as being more than just an end-product and considered to be a fundamental substance. Bilirubin is recognised as acting as an antioxidant and anti-inflammatory agent in serum. Evidence exists that states that it can neutralise free radicals, prevent peroxidation of lipids and protects the cardiovascular system, hepatobiliary system, immune system, neuronal system and pulmonary system 4.
It has been established that bilirubin levels are significantly elevated in COVID-19 patients 5. Patients with abnormal liver function tests were at a significantly higher risk of progressing to a severe disease, such as pneumonia. The presence of abnormal liver function tests became more pronounced during hospitalisation within two weeks, with total bilirubin levels elevated 3 times the upper normal limit 6.

More Information
The Laboratory Working Group of the National Kidney Disease Education Program (NKDEP) released guidelines for the improvement of glomerular filtration rate (GFR) estimation as well as the measurement of serum creatinine (SCr). The recommendation included the recalibration and standardisation of SCr methods to be traceable to the isotope dilution-mass spectrometry (IDMS) reference method. Two IDMS traceable creatinine methods are commercially available: enzymatic assays and compensated Jaffe assays 1.
Of the two enzymatic assays available, the Randox enzymatic creatinine assay converts creatinine to ammonia (NH3) and I-Methylhydantoin. Ammonia then reacts with α-oxoglutarate in the presence of GLDH with oxidation of the co-enzyme NADPH. The decrease of NADPH is proportional to the creatinine concentration and is measured at 340nm 1, 2.
The Randox enzymatic creatinine assay exhibits high sensitivity and reproducibility with the added advantage of liquid ready-to-use reagents with good stability. The enzymatic method represents an improvement for use in the accurate and reliable determination of creatinine.
Creatinine is the end-product of muscle catabolism of creatine. In humans, creatinine production is relatively stable, but mainly depends on muscles mass. Consequently, any physiological changes in muscle mass will cause a variation in the creatinine pool independently of GFR changes.

Randox offer testing solutions for a comprehensive range of cytokines, cytokine receptors and growth factors designed to assist with COVID-19 risk stratification, monitoring of treatment efficacy and recovery. Utilising patented Biochip technology up to 12 cytokines and growth factors may be detected simultaneously from a single patient sample.
Cytokines play a vital role in the immune system and are known to be involved in the body’s response to a variety of inflammatory and infectious diseases. The over stimulation of these cytokines in response to infection is referred to as a ‘cytokine storm’ and strongly correlates with poor disease outcomes.
Cytokine storms are a common complication of SARS-CoV-2 (COVID-19) infection triggering viral sepsis, where viral replication and excessive, uncontrolled systemic inflammation may lead to pneumonitis, Acute Respiratory Distress Syndrome (ARDS), respiratory failure, shock, multiple organ failure, secondary bacterial pneumonia, and potentially death.
Cytokine Array I (12-plex)
Interleukin-1 (IL-1) is a regulatory and inflammatory cytokine, which exists in two forms, (IL-1α) and (IL-1β), which share 25% homology at amino acid level. IL-1α is produced as a biologically active 31 kDa precursor, which undergoes proteolytic cleavage yielding a 17 kDa protein of 159 amino acids.
There are two forms of IL-1, IL-1α and IL-1β ,which share 25% homology at amino acid level. IL-1β is synthesised as a biologically inactive precursor of 269 amino acids with a molecular mass of 31 kDa , which undergoes proteolytic cleavage by IL1 converting enzyme (ICE), which yields a 17kDa protein of 153 amino acids.
Interleukin-2 (IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15 – 18 kDa protein which has varying degrees of glycosylation accounting for the observed molecular weight range. IL-2 regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity.
IL-4 is a glycoprotein synthesised as a precursor protein of 153 amino acids. The first 24 amino acid residue signal peptide is cleaved to produce a 129 amino acid 15-19 kDa protein.
IL-6 is synthesised as a precursor protein of 212 amino acids. The N-terminal 28 amino acid residue signal peptide is cleaved to produce a 21kDa protein. It has two potential N-glycosylation sites which have no effect on bioactivity. Different post-translational alterations such as glycosylation and phosphorylation give various forms of IL-6 with molecular masses of 21.5-28 kDa. The IL-6 receptor is a strongly glycosylated 80 kDa protein of 449 amino acids. Two different forms of the receptor have been described that bind IL-6 with differing affinities, a soluble form of the IL-6 receptor has also been described. The IL-6 receptor is expressed on T cells, mitogen activated B cells, peripheral monocytes and some macrophage and B cell derived tumour cell types. IL-6 also influences antigen-specific immune responses and inflammatory reactions.
IL-8 is a member of a structurally similar family of cytokines called chemokines, which demonstrate chemotactic activity for neutrophils. IL-8 is a non-glycosylated protein of 8 kDa and consists of 99 amino acids with a 22 residue signal peptide that is cleaved to generate a 77 amino acid sequence. IL-8 is produced in response to proinflammatory stimuli. It is produced by monocytes, macrophages, fibroblasts, endothelial cells, keratinocytes, melanocytes, hepatocytes, chondrocytes, T-cells, neutrophils, and astrocytes.
Interleukin-10 (IL-10), alternatively known as B-cell-derived T-cell growth factor (B-TCGF), cytokine synthesis inhibitory factor (CSIF) or T-cell growth inhibitory factor is a homodimeric protein with a molecular weight of 18 kDa. It is produced as a 178 amino acid residue precursor, which is cleaved to give a mature protein of 160 amino acids. IL-10’s primary function is as an anti-inflammatory agent, which inhibits cytokine production by T cells and natural killer cells caused by activation of monocytes/macrophages.
IFN-γ is a cytokine critical to both innate and adaptive immunity, and functions as the primary activator of macrophages, in addition to stimulating natural killer cells and neutrophils. Biologically active interferon gamma is a 20 or 25 kDa glycoprotein depending on its glycosylation state. This lymphokine is synthesised as a 166 amino acid sequence but is cleaved to give a 143 amino acid residue.
Human EGF is produced as a long precursor protein of 1207 amino acids which is released by proteolytic cleavage to give a globular protein of 6.4 kDa consisting of 53 amino acids. EGF is a common mitogenic factor that stimulates the proliferation of different types of cells, especially fibroblasts and epithelial cells. EGF activates the EGF receptor (EGFR/ErbB), which initiates, in turn, intracellular signaling.
Monocyte chemoattractant protein (MCP-1) is part of the chemotactic family of cytokines called chemokines. ). It is a 76 amino acid peptide and has a molecular weight of 8.6 kDa. MCP-1 in particular chondrocytes confirming its role in inflammatory responses. MCP-1 has been implicated in a wide variety of inflammatory diseases such as artherosclerosis, delayed hypersensitivity reactions, rheumatoid arthritis, alveotitis and idiopathic pulmonary fibrosis.
Tumour necrosis factor alpha (TNFα) is a 157 amino acid 26 kDa transmembrane protein which is secreted as a soluble mature 233 amino acid homotrimer of 17 kDa by proteolytic cleavage. TNF-α is secreted by macrophages in response to stimuli for the induction of systemic inflammation. The binding of the ligand TNF-α to the TNF receptor (TNFR1) initiates the pro-inflammatory and pro-apoptotic signaling cascades.
Vascular endothelial growth factor (VEGF), also known as vascular permeability factor (VPF), is secreted as a glycosylated homodimeric protein of 46 kDa that is made up of two 24 kDa subunits linked by disulphide bonds. VEGF is expressed by vascularised tissue such as pituitary, brain, lungs, kidneys, heart and adrenal glands, although it is assumed that all tissues have the potential to produce the growth factor. VEGF is stimulated when cells become deficient in oxygen or glucose or under inflammatory conditions.

Interleukin-5 (IL-5) is a disulphide linked homodimer and belongs to a family of structurally related proteins that includes: interleukin-2, interleukin-4, macrophage colony-stimulating factor, granulocyte macrophage colony-stimulating factor and growth hormone. It is a glycoprotein with the apparent molecular weight of recombinant IL-5 produced by mammalian cells in the range 45 to 60 kDa. The large variation in the molecular weight caused predominantly by the addition of heterogeneous carbohydrate chains.
Interleukin-15 (IL-15) is a 14 to 15 kDa protein of 114 amino acids. It contains 2 disulphide bonds and 2 N-linked glycosylation sites at the C-terminus1. IL-15 is expressed at the mRNA level in numerous normal human tissues in a broad range of cell types, including activated monocytes, dendritic cells, osteoclasts and fibroblasts. IL-15 has an essential role in natural killer (NK) cell development. It activates NK cell proliferation, cytotoxicity, and cytokine production and regulates NK cell/macrophage interaction. Studies have suggested that IL-15 may have a role in establishing innate immune responses and maintaining neutrophil-mediated inflammatory processes.
Granulocyte-macrophage colony stimulating factor (GMCSF) isolated from human sources is glycosylated with an apparent molecular mass of 23 kDa. The mature protein has 127 amino acids and is preceded by a hydrophobic leader sequence of 25 amino acids.
Macrophage inflammatory protein-1α (MIP-1α, CCL3) is a member of the CC chemokine subfamily whose members are known for chemotactic and proinflammatory effects and also for the promotion of homeostasis. MIP-1α is synthesised as a 92 amino acid precursor that is proteolytically processed to a mature protein of about 70 amino acids. MIP-1α has roles in inflammatory responses at sites of injury or infection by recruiting proinflammatory cells.

Matrix metalloproteinase-9 (MMP-9) (gelatinase B) (92 kDa) is a member of the matrix metalloproteinase (MMP) family. MMP-9, one of the most widely investigated MMPs, regulates pathological remodeling processes that involve inflammation and fibrosis.
Soluble IL-2 receptor α (sIL-2Rα) results from the proteolytic cleavage of IL-2Rα at the cell surface by a membrane metalloproteinase; which is encoded by IL2RA on human chromosome. It’s widely noted in research that sIL-2Rα has been found in diseases caused by infections, autoimmune disease and organ transplantation.
Interleukin-6 (IL-6) is a multifunctional cytokine that regulates pleiotropic roles in immune regulation, inflammation, hematopoiesis, and oncogenesis. The IL-6 receptor complex belongs to the haematopoietic receptor superfamily and mediates the biological activities of IL-6. It consists of two distinct membrane bound glycoproteins, an 80 kDa cognate receptor subunit (IL-6R) and a 130 kDa signal-transducing element (gp130). The gp130 subunit is expressed in almost all organs including heart, kidney, spleen, liver, lung, placenta and brain.
Tumour necrosis factor receptor I is one of two specific, high affinity cell surface receptors that function as transducing elements, providing the intracellular signal for cell responses to tumour necrosis factor (TNF). TNF is a proinflammatory cytokine mainly produced by stimulated monocytes, macrophages and T-lymphocyte subsets. It has a key role in host defence and immunosurveillance, mediating complex cellular responses of a different, even contrasting nature. TNFRI has a molecular mass of 55 kDa1 and is expressed by almost all cell types2 especially those cells that are susceptible to the cytotoxic action of TNFI. TNFRs are detectable in normal serum, but their concentration increases significantly in inflammatory and non-inflammatory diseases.
Tumour necrosis factor receptor II (TNFRII) is one of two specific, high affinity cell surface receptors that function as transducing elements, providing the intracellular signal for cell responses to tumour necrosis factor (TNF). TNF is a proinflammatory cytokine mainly produced by stimulated monocytes, macrophages and T-lymphocyte subsets. It has a key role in host defence and immunosurveillance, mediating complex cellular responses of a different, even contrasting nature. TNFRII has a molecular mass of 75 kDa1. Although TNFRII is expressed by almost all cell types, it is expressed primarily by cells of the immune system, cells of myeloid origin and endothelial cells.

Interleukin-3 (IL-3) possesses diverse biological activities and was discovered independently in studies on its biological activities. IL-3 is a heavily glycosylated protein with a polypeptide chain of 133 amino acids. It occurs naturally in a diversity of glycoforms generated by the addition of carbohydrate groups which results in size heterogeneity from 28 to 45 kDa. The function of the extensive carbohydrate modifications of the IL-3 polypeptide is not known however IL-3 has been linked with various diseases including colorectal and pancreatic cancers.
Interleukin-7 (IL-7) is classified as a type 1 short-chain cytokine of the haematopoietin family, a group that also includes IL-2, IL-3, IL-4, IL-5, GM-CSF, IL-9, IL-13, IL-15, M-CSF, and stem cell factor. The human gene for IL-7 is located on chromosome 8q12-13. The amino acid sequence of IL-7 predicts a molecular weight of 17.4 kDa, but glycosylation results in an active protein of 25 kDa. IL-7 appears to be involved in the development of an effective immune system and also in the generation and maintenance of strong and effective cellular immune responses directed against cancer cells, or infectious diseases.
Interleukin-12 (IL-12) is a 75 kDa heterodimeric glycoprotein cytokine composed of disulphide linked p40 (40 kDa) and p35 (35 kDa) subunits that are derived from separate genes1. p35 is expressed in a limiting and tightly regulated fashion by many different cell types, however the expression of p40, though in greater quantities than required for p70 formation, appears to be restricted to antigen presenting cells. IL-12 stimulates IFN production, which is essential in resistance to intracellular protozoan, fungal and bacterial infections and, in addition, tumours. Traditionally, IL-12 is accepted as an important mediator of autoimmunity and is involved in a number of autoimmune diseases including rheumatoid arthritis, psoriasis, inflammatory bowel disease and insulin-dependent diabetes mellitus.
Interleukin-13 (IL-13) is a 12 kDa protein that folds into four I-helical bundles. It contains four potential N-glycosylation sites and four cysteine residues that form two intramolecular disulphide bonds. IL-13 shares a number of structural features and functional characteristics with IL-4. The IL-13 protein is approximately 25% homologous1 with IL-4 and belongs to the same I-helix protein family. IL-13 plays a dominant role in resistance to most gastrointestinal nematodes and also modulates resistance to intracellular organisms by regulating cell mediated immunity. IL-13 is the central mediator of allergic asthma, where it regulates eosinophilic inflammation, mucus secretion, and airway hyperresponsiveness. Although IL-13 is associated primarily with the induction of airway disease, it also has anti-inflammatory properties.
Interleukin 23 (IL-23) is member of the IL-12 family. The IL-12 family consists of cytokines IL-12(p40p35), IL-23(p40p19) and IL-27(EBI13p28), and monomeric and homodimeric p401. IL-23 is a heterodimeric cytokine composed of disulphide linked p19 and p40 subunits. IL-23 plays a role in a signaling pathway that triggers inflammation.
