PURPOSE: To verify whether precision and accuracy of lipids analyses by a new portable device, Cholestech-lipid desktop analyzer (LDX), were in agreement with the guidelines of the National Cholesterol Education Program (NCEP). METHODS: Serum samples from 45 outpatients were collected for the determination of total Cholesterol (TC), HDL-cholesterol (HDL-C) and triglycerides (TG). These samples were analysed simultaneously by the Cholestech-LDX, and by the automatic enzymatic methods routinely used at the Heart Institute's laboratory. Precision was determined by repeating 20 times the evaluation of the same sample of venous blood. Accuracy was established confronting the values of the lipids variables obtained with Cholestech-LDX against the values determined by the automatic enzymatic routine. RESULTS: Accuracy for TC was 1.60% (NCEP < or = 3%), for HDL-C was -2.74% (NCEP < or = 6%) and for TG was 2.11% (NCEP < or = 5%). Precision for CT was 3.05% (NCEP < or = 3%), for HDL-C was 1.05% (NCEP < or = 6%) and for TG was 2.65% (NCEP < 5%). CONCLUSION: Precision and accuracy of lipids evaluation by the Cholestech-LDX are within the guidelines of the National Cholesterol Education Program. Therefore the cholestech-LDX seems to be a reliable alternative to the conventional biochemical routine, allowing population screenings.
