Test Usage

Monitoring of HDL cholesterol in serum
is of clinical importance since an inverse correlation exists
between serum HDL-cholesterol
concentrations and the risk of atherosclerotic disease. Elevated
HDL-cholesterol concentrations are
protective against coronary heart disease, while reduced
HDL-cholesterol concentrations,
particularly in conjunction with elevated triglycerides, increase
the cardiovascular risk.

Test Limitations

Elevated concentrations of free fatty acids and denatured
lipoproteins may cause falsely elevated HDL-cholesterol results.

Abnormal liver function affects lipid metabolism; consequently,
HDL and LDL
results are of limited diagnostic value.

Non-fasting sample results have been observed to be slightly
lower than fasting results.
