Cholesterol is a lipid that is vital for life. It is produced by all cells in the body and is important for the maintenance of cell membrane integrity. Cholesterol is also a precursor to all steroid hormones and bile acids synthesised by the body.
Total cholesterol is part of the lipid profile which is requested to assess a patient's cardiovascular risk.

Total cholesterol is a measure of all the cholesterol in the sample. This can further be broken down into its main constituents, LDL cholesterol and HDL cholesterol, and reported as part of the lipid profile.
Patients with dyslipidaemia (particularly those with elevated LDL cholesterol) are at an increased risk of atherosclerotic cardiovascular disease (ASCVD). Total cholesterol is used to calculate the cholesterol/HDL ratio which is included in some cardiovascular risk algorithms to generate a 5-year or 10-year cardiovascular risk for an individual patient. This risk score is then used to make management decisions.
Total cholesterol results should not be interpreted against a reference interval. Total cholesterol results should be used to assess overall cardiovascular risk, as discussed above.
