Collection and usage attributes

Guide for use:Help on this termRecord the absolute result of the total triglyceride measurement.
Collection methods:Help on this term

Measurement of lipid levels should be carried out by laboratories, or practices, which have been accredited to perform these tests by the National Association of Testing Authorities.

  • To be collected as a single venous blood sample, preferably following a 12-hour fast where only water and medications have been consumed.

Note that to calculate the low-density lipoprotein - cholesterol (LDL-C) from the Friedwald Equation (Friedwald et al, 1972):

  • a fasting level of plasma triglyceride and knowledge of the levels of plasma total cholesterol and high-density lipoprotein - cholesterol (HDL-C) is required,
  • the Friedwald equation becomes unreliable when the plasma triglyceride exceeds 4.5 mmol/L, and
  • that while levels are reliable for the first 24 hours after the onset of acute coronary syndromes, they may be unreliable for the subsequent 6 weeks after an event.
