ng/mL pg/mL mg/L µg/dL

Worked example

51 ng/mL (middle of the reference range) = 51 000 pg/mL

Conversion formulas

pg/mL	pg/mL = ng/mL × 1000	ng/mL = pg/mL × 0.001
mg/L	mg/L = ng/mL × 0.001	ng/mL = mg/L × 1000
µg/dL	µg/dL = ng/mL × 0.1	ng/mL = µg/dL × 10

Good to know

Chromogranin A is reported in ng/mL or pg/mL. The page converts between the units only.

pg/mL × 0.001 = ng/mL (exact factor 0.001).
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	0 – 102
pg/mL	0 – 102 000
mg/L	0 – 0.102
µg/dL	0 – 10.2

Note from the source: Below 102 µg/L (= ng/mL) (Newcastle Hospitals Laboratories); proton pump inhibitors raise the value markedly

Frequently asked questions

How do I convert Chromogranin A from ng/mL to pg/mL?

pg/mL = ng/mL × 1000. In the other direction: ng/mL = pg/mL × 0.001.

What is the reference range of Chromogranin A?

For adults the range is 0 – 102 ng/mL (Newcastle Hospitals Laboratories: Chromogranin A, serum). Reference ranges differ between laboratories and partly by sex and age; use the range printed on your lab report.

Which units are used for Chromogranin A?

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