1.425 ng/mL (middle of the reference range) = 4.31 nmol/L
Conversion formulas
| nmol/L | nmol/L = ng/mL × 3.026 | ng/mL = nmol/L × 0.3305 |
|---|---|---|
| ng/dL | ng/dL = ng/mL × 100 | ng/mL = ng/dL × 0.01 |
| µg/dL | µg/dL = ng/mL × 0.1 | ng/mL = µg/dL × 10 |
| ng/L | ng/L = ng/mL × 1000 | ng/mL = ng/L × 0.001 |
| pmol/L | pmol/L = ng/mL × 3026 | ng/mL = pmol/L × 0.0003305 |

Note from the source: LC-MS/MS, adults: men below 220 ng/dL (2.2 ng/mL); women follicular phase below 80 ng/dL (0.8 ng/mL), luteal phase below 285 ng/dL (2.85 ng/mL), postmenopausal below 51 ng/dL (0.51 ng/mL). Much higher in newborns; interpretation depends on cycle phase and age
