Understanding Cholesterol Reagent

Cholesterol test measurements play a crucial role in diagnosing and managing disorders linked to excessive cholesterol in the blood, alongside lipid and lipoprotein metabolism disorders. Total serum cholesterol analysis is particularly valuable for identifying hyperlipoproteinemia, atherosclerosis, hepatic, and thyroid diseases. Additionally, assessing total and HDL cholesterols, along with triglyceride determination, provides essential insights into predicting coronary heart disease.

Methodology

Researchers Flegg and Richmond initiated total cholesterol assays in saponified serum extracts using “cholesterol dehydrogenase.” Previously, Hernandez and Chaikoff, as well as Hyun et al., isolated a cholesterol ester hydrolase effective in liberating free cholesterol from cholesterol esters. Eventually, in 1974, Allain et al. and Rieschlau et al. successfully merged the esterase and oxidase into a single enzymatic reagent for total cholesterol determination. The Cholesterol reagent complies with the National Cholesterol Education Program’s (NCEP) performance criteria for accuracy. Cholesterol esters in serum undergo hydrolysis by cholesterol esterase (CHE). The resulting free cholesterol undergoes oxidation by cholesterol oxidase (CHO) to cholest-4-en-3-one, accompanied by the generation of hydrogen peroxide (H202). Subsequently, this hydrogen peroxide reacts with 4-aminoantipyrine and phenol in the presence of peroxidase, producing a chromophore. The resulting red quinoneimine dye can be measured spectrophotometrically at 540/600 nm to determine the increase in absorbance.
