About CO-Oximetry EQA

Co-oximetry is a methodology, also known as spectrophotometry, that measures the levels of the oxygen-carrying protein haemoglobin, which is the chief component of red blood cells. Co-oximetry is a useful tool in that it helps determine the levels of various forms of haemoglobin.

Spectrophotometric methods date back to studies by Sir Isaac Newton in the 1600s. Work by Lambert (1760) and Beer (1852) resulted in the Beer-Lambert law which describes the transmission / absorption of light in solutions (Chatburn, 2014).

A high value for the Co-Oximetry Blood Test may indicate, among other things:

Carbon monoxide poisoning
Congenital haemoglobin disorder
