Worked example
73 µmol/L (middle of the reference range) = 1.13 mg/dL
Conversion formulas
| mg/dL | mg/dL = µmol/L × 0.01551 | µmol/L = mg/dL × 64.45 |
|---|---|---|
| mg/L | mg/L = µmol/L × 0.1552 | µmol/L = mg/L × 6.445 |
| µg/dL | µg/dL = µmol/L × 15.52 | µmol/L = µg/dL × 0.06445 |
Good to know
Histidine in plasma is reported in µmol/L or in mg/dL. It is part of the plasma amino acid profile.
- mg/dL × 64.45 = µmol/L (exact factor 64.454).
- Ranges depend on age and fasting state, so the range shown applies to fasting adults; the sample should reach the laboratory quickly and cooled.
Reference range
| Unit | Adults |
|---|---|
| mg/dL | 0.7292 – 1.536 |
| µmol/L | 47 – 99 |
| mg/L | 7.292 – 15.36 |
| µg/dL | 729.2 – 1536 |
