These include detection of the fats, cholesterol and lipid components of blood including LDL, HDL, Triglycerides. blood glucose and Glycosylated hemoglobin is measured for detection of diabetes. C-reactive protein (CRP) and other protein markers like Apolipoprotein A1 and B are wont to detect inflammation which will cause heart diseases.
