Worked example

278 µg/24 h (middle of the reference range) = 1 815 nmol/24 h

Conversion formulas

nmol/24 h	nmol/24 h = µg/24 h × 6.528	µg/24 h = nmol/24 h × 0.1532

Good to know

Dopamine in 24-hour urine is reported in µg/24 h or in nmol/24 h.

µg/24 h × 6.53 = nmol/24 h (1 nmol/24 h = 0.153 µg/24 h).
Some foods and drugs affect the result, so laboratories give instructions before the collection. 24-hour urine results depend on a complete collection; a missed portion lowers the value.
