HDL Cholesterol (HDLC, high density lipoprotein cholesterol)
See also
Cholesterol, total; LDL cholesterol [LDLC]; lipid study.
Specimen
--------
5 ml blood, lithium-heparin or serum tube.
 
Patient does not need to be fasting.
Prolonged tourniquet use can artefactually increase levels by up to
20%.
Test availability
Assayed daily.
Reference interval
plasma or serum
adult
M 0.7 – 1.9 mmol/L
F 0.9 – 2.4 mmol/L
 
The National Heart Foundation recommends that total HDL-cholesterol in
adults be at least 1.0 mmol/L.
Uncertainty of measurement: CVa: RMH, 2.7% at 1.9 mmol/L.
Clinical applications
Assessment of lipid status, particularly as a risk factor for coronary
artery disease.
Clinical interpretation
HDL-C is protective against vascular disease caused by lipid
deposition.
HDL-C levels > 1.0 mmol/L are associated with a decreased risk of
coronary artery disease.
HDL-C increases with
*
exercise
*
moderate alcohol consumption
*
some lipid altering drug therapy.
Levels are unreliable for up to 8 weeks with acute illness (e.g.,
myocardial infarction, major acute infection) and assessment should
not be attempted during this time.
