Enter total cholesterol, HDL and triglycerides from the same lipid panel. We estimate LDL cholesterol with the Friedewald equation and also show non-HDL cholesterol.
Non-HDL cholesterol: 3.90 mmol/L
The equation is an estimate and may differ from direct measurement, especially when LDL is low or triglycerides are elevated.
Please note: An LDL target depends on overall cardiovascular risk, age, diabetes, blood pressure, smoking and prior disease — not one universal normal value. Treatment decisions require the full clinical picture.
Friedewald equation: LDL = total cholesterol − HDL − triglycerides/2.2 in mmol/L; the divisor is 5 in mg/dL. Published by Friedewald et al. in 1972, it is not valid when triglycerides are ≥4.5 mmol/L (400 mg/dL).
Subtract HDL and triglycerides divided by 2.2 in mmol/L, or by 5 in mg/dL, from total cholesterol. We also calculate non-HDL as total cholesterol minus HDL.
There is no single LDL target for everyone. The appropriate level depends on overall cardiovascular risk, prior disease, diabetes, blood pressure, smoking and other factors.
The Friedewald equation does not apply at triglycerides of 4.5 mmol/L (400 mg/dL) or above and loses accuracy with low LDL or elevated triglycerides. A laboratory result or another validated equation is needed in those settings.
