Collection and usage attributes

Guide for use:Record the absolute result of the total triglyceride measurement.
Collection methods:

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 8 weeks after an event.
