What is this test?
HDL cholesterol measures cholesterol carried in high-density lipoproteins. It contributes to risk assessment but is not a treatment target that should be interpreted in isolation.
Why might it be ordered?
- As part of a lipid profile for cardiovascular risk assessment.
- To follow the overall lipid pattern during treatment or lifestyle change.
What sample is needed?
A blood sample is required. The laboratory chooses the correct tube and handles the sample for this test.
How should you prepare?
Ask the laboratory whether you need to fast or attend at a particular time. Do not stop or change medicines or supplements unless your clinician tells you to.
How should you understand the result?
A higher HDL value does not cancel the risk from high LDL or other factors. Clinicians use the full lipid profile and your overall risk.
