CHOLESTEROL: The Cholesterol Oxidase peroxidase (CHOD-PAP) enzymatic method is used. The cholesterol esterase enzyme catalyzes the hydrolysis of cholesterol and free fatty and free fatty acids. Free cholesterol, including that originally present in the sample, is then oxidized by the enzyme cholesterol oxidase (CHOD) to cholest-4-en-3-one, by using molecular oxygen as the electron acceptor and concurrently producing hydrogen peroxide (H2O2). The H2O2 produced is then used in a subsequent chromogenic oxidative coupling reaction, catalyzed by the enzyme peroxidase, in the presence of a redox indicator system, which leads to the formation of a colored compound, absorbing light at 550 nm. The increase in absorbance is directly proportional to the cholesterol concentration in the sample. HDL-Cholesterol: The Accelerator Selective Detergent method is applied. The determination of HDL-Cholesterol is based on the following reactions: LDL, VLDL, and chylomicrons are neutralized by the combined action of the enzymes Cholesterol Oxidase, Peroxidase, accelerators and N,N-bis-(4-sulfobutyl)-m-toluidine-disodium (DSBmT). HDL remaining in the sample is disrupted by the action of a selective detergent and cholesterol is converted to △4 Cholestenone by the enzymatic action of Cholesterol Esterase and Cholesterol Oxidase, with the subsequent production of H2O2, which reacts with DSBmT and 4-aminoantipyrine in the presence of Peroxidase to a colored complex that absorbs light at 590 nm. The absorbance measured is proportional to the concentration of HDL-Cholesterol in the sample. LDL-Cholesterol: The Selective Detergent method is applied. The method is in a two-reagent format and depends on the properties of a unique detergent. The first detergent solubilizes only the non-LDL lipoprotein particles. The cholesterol released is consumed by cholesterol esterase and cholesterol oxidase in a non-color forming reaction. The second detergent solubilizes the remaining LDL particles, and a chromogenic coupler allows for color formation. The enzyme reaction with LDL-Cholesterol in the presence of the coupler at 590 nm produces color that is proportional to the amount of LDL cholesterol present in the sample. TRIGLYCERIDES: The enzymatic glycerol-3-phosphate-peroxidase (GPO-POD) method is used. The method enzymatically hydrolyzes by lipase to free fatty acids and glycerol is phosphorylated by adenosine triphosphate (ATP) with glycerokinase (GK) to produce glycerol-3-phosphate and adenosine diphosphate (ADP). Glycerol-3-phosphate-oxidase oxidizes glycerol-3-phosphate to dihydroxyacetone phosphate and H2O2. The catalytic action of peroxidase (POD) forms quinoneimine from H202, aminoantipyrine, and Dihydrate (N-Ethyl-N-(2hydroxy-3-sulfopropyl)-m-toluidine (TOOS). The absorption change at 550 nm is proportional to the triglycerides concentration in the sample.

The Medicon Hellas Albumin, Medicon Hellas Calcium, Medicon Hellas Creatinine, Medicon Hellas Glucose, Medicon Hellas Direct Bilirubin, Medicon Hellas Total Bilirubin, and Medicon Hellas Urea Nitrogen are reagents for use with Diatron Pictus 500 Clinical Chemistry Analyzers. They are test systems for the quantitative measurement of albumin, calcium, creatinine, glucose, direct and total bilirubin, and urea nitrogen in human serum and urine where clinically applicable. The methods employed are photometric, utilizing reactions between the sample and reagents to produce a colored chromophore or a change in absorbance that is proportional to the concentration of the analyte. The analyzer photometer reads the absorbances at time intervals dictated by the method application stored in the analyzer memory, and the change in absorbance is calculated automatically.
