Special Precautions/Comments:

For guidance on interpreting lipid results and investigating dyslipidaemia consult the Northern England Evaluation and Lipid Intensification (NEELI) Guidelines.

Additional Information:

Fasting lipid profile includes:

• Total cholesterol
• Triglycerides
• High density lipoprotein (HDL) cholesterol – often referred to as ‘good’ cholesterol
• Low density lipoprotein (LDL) cholesterol – often referred to as ‘bad’ cholesterol, calculated using the Freidewald equation (invalid if triglycerides >4.5 mmol/L, fasting samples only)
• Non-HDL cholesterol – calculated by total cholesterol-HDL cholesterol (alternative to LDL on a non-fasting sample)
• Cholesterol/HDL ratio – used to evaluate cardiovascular risk

Cardiovascular risk can be calculated using https://qrisk.org/three/

Lipid profiles may be added to lipaemic samples.
