Worked example
130 pg/mL (middle of the reference range) = 13 ng/dL
Conversion formulas
| ng/dL | ng/dL = pg/mL × 0.1 | pg/mL = ng/dL × 10 |
|---|---|---|
| pmol/L | pmol/L = pg/mL × 3.467 | pg/mL = pmol/L × 0.2884 |
| µg/L | µg/L = pg/mL × 0.001 | pg/mL = µg/L × 1000 |
| nmol/L | nmol/L = pg/mL × 0.003467 | pg/mL = nmol/L × 288.4 |
