LDL-C via Martin-Hopkins Equation Calculator

LDL = TC − HDL − TG / adjustable_factor (≈ 5.0-6.5).

Compute LDL-cholesterol via the Martin-Hopkins equation, which uses an adjustable TG:VLDL ratio (≈ 5.0 - 6.5) instead of the fixed 5 of Friedewald. Particularly more accurate for TG ≥ 200 mg/dL or LDL < 70. Simplified average factor (default 6) used here; for more granular factor tables, see the Martin-Hopkins 180-cell publication.
