Worked example
5.9 µmol/L (middle of the reference range) = 1.84 mg/L
Conversion formulas
| mg/L | mg/L = µmol/L × 0.3125 | µmol/L = mg/L × 3.2 |
|---|---|---|
| mg/dL | mg/dL = µmol/L × 0.03125 | µmol/L = mg/dL × 32 |
| µg/dL | µg/dL = µmol/L × 31.25 | µmol/L = µg/dL × 0.032 |
| µg/L | µg/L = µmol/L × 312.5 | µmol/L = µg/L × 0.0032 |
| nmol/L | nmol/L = µmol/L × 1000 | µmol/L = nmol/L × 0.001 |
Good to know
Phytanic acid in plasma is reported in µmol/L or in mg/L.
- mg/L × 3.20 = µmol/L (exact factor 3.1997).
- It is read together with the ratios of the very long chain fatty acids; the sample can be taken without fasting.
