Background and Objectives: Dyslipidemia is a family of lipoprotein metabolism disorders manifested by elevated total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and reduced high density lipoprotein cholesterol (HDL-C) concentrations in the blood.[1] Dyslipidemia was defined according to the criteria of the National Cholesterol Education Program Adult Treatment Panel III. Hypercholesterolemia was declared for participants with either a total cholesterol ˃ 200 mg/dL or an LDL cholesterol ˃ 130 mg/dL while HDL hypocholesterolemia was at HDL cholesterol ˂ 40 mg/dL. Hypertriglyceridemia was declared for triglyceride plasma level ˃ 150 mg/dL. A combination of hypercholesterolemia and hypertriglyceridemia was classified as mixed hyperlipidemia while atherogenic dyslipidemia was a combination of HDL hypocholesterolemia, hypertriglyceridemia and LDL hypercholesterolemia. Material and Methods : The study population included 100 subjects in which 50 were newly diagnosed patients of dyslipidemia and rest 50 healthy attending both outpatients and inpatients department Biochemistry of Rajshree Medical Research Institute Bareilly. Results: In our study we found the mean values of ADA, TC, HDL-C, LDL-C and TG in cases and controls respectively.
