nmol/L pmol/L

Worked example

0.01 nmol/L (middle of the reference range) = 10 pmol/L

Conversion formulas

pmol/L	pmol/L = nmol/L × 1000	nmol/L = pmol/L × 0.001

Good to know

Acetylcholine receptor antibodies are reported in nmol/L (binding assay); some laboratories use pmol/L.

1 nmol/L = 1000 pmol/L.
A negative result does not exclude myasthenia gravis; further antibodies (for example MuSK) can be tested.

Reference range

Unit	Adults
nmol/L	0 – 0.02
pmol/L	0 – 20

Note from the source: Normally none, or below 0.02 nmol/L (MedlinePlus). Positive in most people with generalised myasthenia gravis; a negative result does not exclude it

Frequently asked questions

How do I convert Acetylcholine receptor antibodies from nmol/L to pmol/L?

pmol/L = nmol/L × 1000. In the other direction: nmol/L = pmol/L × 0.001.

What is the reference range of Acetylcholine receptor antibodies?

For adults the range is 0 – 0.02 nmol/L (MedlinePlus (NLM): Acetylcholine receptor antibody). Reference ranges differ between laboratories and partly by sex and age; use the range printed on your lab report.

Which units are used for Acetylcholine receptor antibodies?

Common units are nmol/L, pmol/L.
