Worked example
12 µg/mL (middle of the reference range) = 70.1 µmol/L
Conversion formulas
| µmol/L | µmol/L = µg/mL × 5.84 | µg/mL = µmol/L × 0.1712 |
|---|---|---|
| mg/dL | mg/dL = µg/mL × 0.1 | µg/mL = mg/dL × 10 |
| µg/dL | µg/dL = µg/mL × 100 | µg/mL = µg/dL × 0.01 |
Good to know
Gabapentin is reported in µg/mL or µmol/L. The page converts between the units only.
- µmol/L × 0.1712 = µg/mL (exact factor 0.1712).
- The range shown is a guide from the named source; targets and reference ranges differ between laboratories, methods and indications, so compare with the range on your own report.
Reference range
| Unit | Adults |
|---|---|
| µg/mL | 3 – 21 |
| µmol/L | 17.52 – 122.6 |
| mg/dL | 0.3 – 2.1 |
| µg/dL | 300 – 2100 |

Note from the source: 3-21 mg/L (20-120 µmol/L) (ILAE ranges as listed in Drug Des Devel Ther 2018, blood taken before the next dose). Individual targets differ. An NHS laboratory quotes 2-20 mg/L (Leeds).
