There are five major groups of lipoproteins (chylomicrons, VLDL, IDL, LDL, and HDL). Where LDL stands for low-density lipoprotein and VLDL stands for very-low-density lipoprotein.
LDL Calculation Formula
We can calculate LDL using Friedewald's equation:
LDL = TC - HDL – (0.2 × TG)
or
LDL-C (mg/dL) = total cholesterol – HDL-C – (triglycerides/5)
Where, TC = total cholesterol, HDL = high-density lipoprotein, TG = triglycerides.
LDL Cholesterol Normal Range
- Less than 100 mg/dL (3.4 mmol/L)
VLDL Calculation Formula
We can calculate VLDL using Friedewald's equation:
VLDL = Triglycerides / 5
VLDL normal range
- Normal VLDL levels range from 2 mg/dL to 30 mg/dL (0.1 mmol/L to 1.7 mmol/L).
Total Cholesterol Calculation Formula
Total cholesterol (TC) = LDL + HDL + VLDL. [Where VLDL ≅ TG/5]
