µg/L nmol/L ng/dL ng/L

Worked example

14.5 nmol/L (middle of the reference range) = 0.851 µg/L

Conversion formulas

µg/L	µg/L = nmol/L × 0.05869	nmol/L = µg/L × 17.04
ng/dL	ng/dL = nmol/L × 5.869	nmol/L = ng/dL × 0.1704
ng/L	ng/L = nmol/L × 58.69	nmol/L = ng/L × 0.01704

Good to know

Nickel in serum is reported in nmol/L or in µg/L.

µg/L × 17.04 = nmol/L (exact factor 17.04).
Collection tubes and needles can add nickel, so trace-element-free tubes are used.

Reference range

Unit	Adults
µg/L	0.4401 – 1.262
nmol/L	7.5 – 21.5
ng/dL	44.02 – 126.2
ng/L	440.2 – 1262

Frequently asked questions

How do I convert Nickel (serum) from nmol/L to µg/L?

µg/L = nmol/L × 0.05869. In the other direction: nmol/L = µg/L × 17.04.

What is the reference range of Nickel (serum)?
