Calculated Results

Non-HDL Cholesterol

150 mg/dL
Non-HDL-C = TC – HDL

Friedewald Method

LDL-C: 100.0 mg/dL
VLDL-C: 30.0 mg/dL
LDL = TC – HDL – (TG / 5)

Martin/Hopkins Method

LDL-C: 98.5 mg/dL
VLDL-C: 31.5 mg/dL
LDL = TC – HDL – (TG / factor)

Sampson Method

LDL-C: 102.3 mg/dL
VLDL-C: 28.7 mg/dL
LDL = TC/0.948 – HDL/ 0.971 – (TG/8.56 + (TG* nonHDL)/2140 – (TG*2)/16100) – 9.44
