Term Description

The Martin-Hopkins method for calculating LDL cholesterol uses a variable value for the triglyceride adjustment factor, where the adjustment factor depends on the measured triglyceride and non-HDL cholesterol levels. The calculation used since the 1970s, called the Friedewald formula, uses a fixed adjustment factor of 5, which results in an inaccurate calculated LDL result when triglycerides are high or LDL-C levels are low. PMID: 24240933
