Key facts

Cholesterol in LDL [Moles/volume] in Serum or Plasma by Calculated by Martin-Hopkins
Cholesterol.in LDL
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.
