Worked example
0.75 µmol/L (middle of the reference range) = 0.224 mg/L
Conversion formulas
| mg/L | mg/L = µmol/L × 0.2985 | µmol/L = mg/L × 3.35 |
|---|---|---|
| µg/dL | µg/dL = µmol/L × 29.85 | µmol/L = µg/dL × 0.0335 |
| µg/L | µg/L = µmol/L × 298.5 | µmol/L = µg/L × 0.00335 |
| nmol/L | nmol/L = µmol/L × 1000 | µmol/L = nmol/L × 0.001 |
Good to know
Pristanic acid in plasma is reported in µmol/L or in mg/L.
- mg/L × 3.35 = µmol/L (exact factor 3.3501).
- It is read together with the ratios of the very long chain fatty acids; the sample can be taken without fasting.
