HDL CHOLESTEROL (HDL-c) - (P)

Test Code: LIPP

Test Indications: High density lipoproteins (HDL) are responsible for the transport of cholesterol from peripheral cells to the liver for excretion. HDL cholesterol testing is used in combination with total cholesterol and triglyceride determination for atherosclerotic risk assessment as well as in the diagnosis and monitoring of lipid and lipoprotein metabolic disorders.
An individual’s level of risk for cardiovascular disease associated with their lipoprotein profile should be managed according to current practice guidelines. Therapy thresholds and targets are based on current guidelines.

Recommendations:

Patient Preparation Instructions: Fasting or non-fasting specimen, as requested by the ordering physician.
 
If fasting specimen is required:
Adult: fast 8-12 hours
Infant: collect just before next feeding

Age	Gender	Decision Limit	Comment
<20 y	All	≥1.00 mmol/L	Desired: >1.20 mmol/L Borderline: 1.00 - 1.20 mmol/L Increased risk:  <1.00 mmol/L   HDL-C <0.30 mmol/L may be associated with genetic dyslipidemias. Refer to specialist.
≥20 y	Male	≥1.00 mmol/L	HDL-C < 1.00 mmol/L indicates risk for metabolic syndrome.
≥20 y	Female	≥1.30 mmol/L	HDL-C < 1.30 mmol/L indicates risk for metabolic syndrome.
