How do I convert Tryptase from ng/mL to µg/dL?

µg/dL = ng/mL × 0.1. In the other direction: ng/mL = µg/dL × 10.

What is the reference range of Tryptase?

For adults the range is 2 – 14 ng/mL (Newcastle Hospitals Laboratories: Serum Tryptase). Reference ranges differ between laboratories and partly by sex and age; use the range printed on your lab report.

Which units are used for Tryptase?

Common units are ng/mL, µg/dL, ng/dL, ng/L.

Immunology & cytokines

Tryptase unit converter

Mast cell enzyme; marker of anaphylaxis and mastocytosis

Also known as: Mast cell tryptase, Serum tryptase

Converter

Enter a value in any unit and all other units fill in.

ng/mL = µg/L µg/dL ng/dL ng/L

Worked example

8 ng/mL (middle of the reference range) = 0.8 µg/dL

Conversion formulas

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
ng/L	ng/L = ng/mL × 1000	ng/mL = ng/L × 0.001

Good to know

Tryptase is reported in ng/mL or µg/L. The page converts between the units only.

1 µg/L = 1 ng/mL; the two notations are interchangeable.
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
ng/mL = µg/L	2 – 14
µg/dL	0.2 – 1.4
ng/dL	200 – 1400
ng/L	2000 – 14 000
