Cholesterol


Test Background
The fasting lipid profile assesses total cholesterol and total triglycerides, in addition to the high and low density lipoprotein cholesterol fractions, from which ratios may be derived. A patient’s lipid status is an independent modifier of cardiovascular disease pathology. Its subsequent targeting, by pharmacological or dietary means, lowers the risk for developing such diseases.


Clinical Indications
Family history of cardiovascular or other thrombotic events Diagnosis and monitoring of hyperlipidaemia Monitoring of high-risk groups, eg. hypertensive, obese, diabetics, etc.


Reference Range

Desirable : 0-5 mmol/L


Sample Required
SST (gold top)


Sample Volume
0.5 mL


Turnaround Time
1 day


Notes
Non-HDL cholesterol (total chol minus HDL chol) is recommended for CVD risk prediction; fasting samples are not required for this.

Non-HDL cholesterol targets for patients treated for CVD risk reduction are 40 % reduction from baseline (NICE CG181, 2014) or <2.5 mmol/L (JBS3. Heart 2014;100:ii1)
