Clinical Significance

Evaluate lipid status and metabolic disorders. High levels of cholesterol may be caused by an inherited defect in lipoprotein metabolism, by disease of the endocrine system, by liver disease, or by renal disease. Low levels of cholesterol in the serum may reflect an inherited deficiency of either LDL or HDL, or they may reflect impairment of liver function. Various hormone conditions are also related to cholesterol levels. Increased serum cholesterols are found in cases of myeloma, macroglobulinemia of Waldenstrom, polycythemia anemia, and with increased estrogens. Pregnancy is accompanied by a moderate increase. Cholesterol is increased in early hepatitis, obstructed bile ducts, primary biliary cirrhosis, nephrotic syndrome, and diabetic meningitis. Finally, through much controversy, it appears that cholesterol is implicated in atherosclerotic heart disease (ASHD).
