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

                                     High CVD risk goal    Minimum goal
Total Cholesterol                    <4.0                        <5.0
Non-HDL Cholesterol               <3.0                        <4.0

See CVD risk prediction charts in BNF for primary prevention.
Please note LDL calculation is only valid if patient was fasting.
 
If Tg >4.5,
LDL Not valid when TG >4.5/Not Fasting. Use Non-HDL Cholesterol target.
