LDL (mg/dL) = Complete Ldl cholesterol (mg/dL) – HDL (mg/dL) – (Triglycerides (mg/dL)/5)
This equation is derived from the idea of mass-balance equations, which assume that the sum of all lipoproteins within the bloodstream stays fixed. By rearranging this equation, we will isolate LDL ldl cholesterol and calculate its degree.
Assumptions and Limitations of the Friedewald Equation
The Friedewald equation depends on a number of assumptions, together with:
* The presence of very-low-density lipoprotein (VLDL) and chylomicrons is negligible.
* The degrees of intermediate-density lipoprotein (IDL) aren’t considerably affected by the presence of VLDL or chylomicrons.
Nonetheless, these assumptions might not all the time maintain true, significantly in people with sure metabolic issues or these taking particular drugs. Moreover, this equation will not be relevant for people with extraordinarily excessive triglyceride ranges (>400 mg/dL) or low HDL ranges (<40 mg/dL).
LDL (mg/dL) Complete Ldl cholesterol (mg/dL) HDL (mg/dL) Triglycerides (mg/dL) Calculation:
- Complete Ldl cholesterol (mg/dL): 130
- HDL (mg/dL): 50
- Triglycerides (mg/dL): 100
On this instance, the calculated LDL degree could be:
LDL (mg/dL) = 130 – 50 – (100/5) = 80 mg/dL.
