752.5 pmol/L (middle of the reference range) = 205 pg/mL
Conversion formulas
| pg/mL | pg/mL = pmol/L × 0.2724 | pmol/L = pg/mL × 3.671 |
|---|---|---|
| µg/L | µg/L = pmol/L × 0.0002724 | pmol/L = µg/L × 3671 |
| nmol/L | nmol/L = pmol/L × 0.001 | pmol/L = nmol/L × 1000 |
| ng/dL | ng/dL = pmol/L × 0.02724 | pmol/L = ng/dL × 36.71 |
