Worked example
27 µmol/L (middle of the reference range) = 0.241 mg/dL
Conversion formulas
| mg/dL | mg/dL = µmol/L × 0.008908 | µmol/L = mg/dL × 112.3 |
|---|---|---|
| mg/L | mg/L = µmol/L × 0.08909 | µmol/L = mg/L × 11.22 |
| µg/dL | µg/dL = µmol/L × 8.909 | µmol/L = µg/dL × 0.1122 |
| µg/L | µg/L = µmol/L × 89.09 | µmol/L = µg/L × 0.01122 |
Good to know
Alanine in cerebrospinal fluid is reported in µmol/L or in mg/dL.
- mg/dL × 112.3 = µmol/L (exact factor 112.26).
- CSF amino acid ranges are age-dependent and are often read as a CSF/plasma ratio; this range applies to older children and adults.
