Worked example

47.5 ng/mL (middle of the reference range) = 146 nmol/L

Conversion formulas

nmol/L	nmol/L = ng/mL × 3.083	ng/mL = nmol/L × 0.3244
µmol/L	µmol/L = ng/mL × 0.003083	ng/mL = µmol/L × 324.4
µg/dL	µg/dL = ng/mL × 0.1	ng/mL = µg/dL × 10
ng/dL	ng/dL = ng/mL × 100	ng/mL = ng/dL × 0.01

Reference range
