µg/L = ng/mL µg/dL ng/dL

Worked example

29 µg/L (middle of the reference range) = 2.9 µg/dL

Conversion formulas

µg/dL	µg/dL = µg/L × 0.1	µg/L = µg/dL × 10
ng/dL	ng/dL = µg/L × 100	µg/L = ng/dL × 0.01

Reference range

Unit	Adults
µg/L = ng/mL	4 – 54
µg/dL	0.4 – 5.4
ng/dL	400 – 5400

Frequently asked questions

How do I convert Eosinophil cationic protein from µg/L to µg/dL?

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

What is the reference range of Eosinophil cationic protein?

For adults the range is 4 – 54 µg/L (LabCorp Test Menu: Eosinophil cationic protein (ECP)). Reference ranges differ between laboratories and partly by sex and age; use the range printed on your lab report.

Which units are used for Eosinophil cationic protein?

Common units are µg/L, µg/dL, ng/dL.
