Clinical Laboratory Test:
serum — HDL-cholesterol

Information displayed below is a subset of the entire knowledge base and may be incomplete intensionally or inadvertently. If you detect a serious error or want access to the complete knowledge base, please contact us.


The clinical test HDL-cholesterol is a measure of the amount of high-density lipoprotein (HDL) cholesterol in a patient's serum. HDL cholesterol is a type of cholesterol that helps protect against heart disease. To obtain a patient's HDL-cholesterol level, a sample of their blood is taken and sent to a laboratory for analysis. The laboratory will then measure the amount of HDL cholesterol in the sample using a variety of methods, such as an enzymatic colorimetric assay, a direct homogeneous assay, or a combination of both. The results of the test will be reported as a numerical value, which can be used to assess the patient's risk of developing heart disease.
