Lipoprotein-Cholesterol Analysis during Screening: Accuracy and Reliability

Abstract

Total cholesterol can be reliably measured in samples from fasting or nonfasting persons. The values in capillary blood samples were slightly higher than those in venous samples. Screening HDL-cholesterol values were too variable to establish the HDL-cholesterol level reliably. Participants with high LDL-cholesterol levels were identified as accurately by measuring total cholesterol only when compared with calculating the LDL-cholesterol level from total cholesterol, triglyceride, and HDL-cholesterol concentrations.
