Worked example

64.25 µmol/L (middle of the reference range) = 21.9 mg/L

Conversion formulas

mg/L	mg/L = µmol/L × 0.3406	µmol/L = mg/L × 2.936
mg/dL	mg/dL = µmol/L × 0.03406	µmol/L = mg/dL × 29.36
µg/dL	µg/dL = µmol/L × 34.06	µmol/L = µg/dL × 0.02936

Good to know

Behenic acid (C22:0) in plasma is reported in µmol/L or in mg/L.

mg/L × 2.94 = µmol/L (exact factor 2.9362).
It is read together with the ratios of the very long chain fatty acids; the sample can be taken without fasting.
