ng/mL = µg/L ng/dL ng/L

Worked example

0.05 ng/mL (middle of the reference range) = 5 ng/dL

Conversion formulas

ng/dL	ng/dL = ng/mL × 100	ng/mL = ng/dL × 0.01
ng/L	ng/L = ng/mL × 1000	ng/mL = ng/L × 0.001

Reference range

Unit	Adults
ng/mL = µg/L	0 – 0.1
ng/dL	0 – 10
ng/L	0 – 100

Note from the source: Healthy people have below 0.1 ng/mL (some papers give 0.05). Values of 0.5 ng/mL and above suggest sepsis; thresholds for antibiotic decisions are 0.1, 0.25 and 0.5 ng/mL depending on the setting. 1 ng/mL = 1 µg/L
