Worked example
37 µmol/L (middle of the reference range) = 0.889 mg/dL
Conversion formulas
| mg/dL | mg/dL = µmol/L × 0.02403 | µmol/L = mg/dL × 41.61 |
|---|---|---|
| mg/L | mg/L = µmol/L × 0.2403 | µmol/L = mg/L × 4.161 |
| µg/dL | µg/dL = µmol/L × 24.03 | µmol/L = µg/dL × 0.04161 |
| µg/L | µg/L = µmol/L × 240.3 | µmol/L = µg/L × 0.004161 |
Good to know
Cystine in plasma is reported in µmol/L or in mg/dL. It is part of the plasma amino acid profile.
- mg/dL × 41.61 = µmol/L (exact factor 41.615).
- 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 | 0.3364 – 1.442 |
| µmol/L | 14 – 60 |
| mg/L | 3.364 – 14.42 |
| µg/dL | 336.4 – 1442 |
| µg/L | 3364 – 14 418 |

Note from the source: Adults 14-60 µmol/L (MedlinePlus, plasma amino acid profile; children have different ranges). Ranges vary between laboratories and with fasting state
