Multicentre evaluation of a non-wipe system for the rapid determination of total cholesterol in capillary blood, Accutrend Cholesterol on Accutrend GC.
Accutrend Cholesterol, a non-wipe test for the determination of total cholesterol in capillary blood, was evaluated at four clinical centres. Cholesterol determinations with the Accutrend system using capillary blood were compared with results obtained with the cholesterol oxidase/p-aminophenazone (CHOD-PAP) method using the respective capillary sera. Triacylglycerols, uric acid and haematocrit were determined to evaluate potential interference. Imprecision measurements were performed with venous blood. To examine the reproducibility of results from lot to lot, three different lots of test strips were included in these investigations. Results with Accutrend Cholesterol agree with those of the comparison method within systematic differences of +2.5% to -3.2%, depending on the lot. There was no interference by triacylglycerols up to 10.28 mmol/l (900 mg/dl), by uric acid 60 to 400 mumol/l (1 mg/dl to 7 mg/dl), or by haematocrits between 0.35 and 0.54. Impression data show coefficients of variation of generally less than 5%. Thus Accutrend Cholesterol proved to be a reliable system for the determination of total cholesterol.
