Worked example
6 µmol/L (middle of the reference range) = 0.045 mg/dL
Conversion formulas
| mg/dL | mg/dL = µmol/L × 0.007507 | µmol/L = mg/dL × 133.2 |
|---|---|---|
| mg/L | mg/L = µmol/L × 0.07507 | µmol/L = mg/L × 13.32 |
| µg/dL | µg/dL = µmol/L × 7.507 | µmol/L = µg/dL × 0.1332 |
| µg/L | µg/L = µmol/L × 75.07 | µmol/L = µg/L × 0.01332 |
| nmol/L | nmol/L = µmol/L × 1000 | µmol/L = nmol/L × 0.001 |
Good to know
Glycine in cerebrospinal fluid is reported in µmol/L or in mg/dL.
- mg/dL × 133.2 = µmol/L (exact factor 133.21).
- CSF amino acid ranges are age-dependent and are often read as a CSF/plasma ratio; this range applies to older children and adults.
Reference range
| Unit | Adults |
|---|---|
| mg/dL | 0.015 – 0.0751 |
| µmol/L | 2 – 10 |
| mg/L | 0.1501 – 0.7507 |
| µg/dL | 15.01 – 75.07 |
| µg/L | 150.1 – 750.7 |
| nmol/L | 2000 – 10 000 |
