Worked example
47.5 nmol/L (middle of the reference range) = 3.56 µg/L
Conversion formulas
| µg/L | µg/L = nmol/L × 0.07491 | nmol/L = µg/L × 13.35 |
|---|---|---|
| µg/dL | µg/dL = nmol/L × 0.007492 | nmol/L = µg/dL × 133.5 |
| ng/dL | ng/dL = nmol/L × 7.492 | nmol/L = ng/dL × 0.1335 |
| ng/L | ng/L = nmol/L × 74.92 | nmol/L = ng/L × 0.01335 |
Good to know
Arsenic (blood) is reported in nmol/L or µg/L. The page converts between the units only.
- µg/L × 13.35 = nmol/L (exact factor 13.35).
- 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 |

Note from the source: Blood below 95 nmol/L (about 7 µg/L) (University Hospitals Sussex). Seafood raises arsenic; avoid it for several days before the test
