What it measures
- Acetylcholine receptor (AChR) antibodies — The most common antibody found in MG; a positive result supports the diagnosis.
- Muscle-specific kinase (MuSK) antibodies — Found in some people with MG who do not have AChR antibodies.
- LRP4 antibodies — A less common antibody that can be present in MG.
- Agrin antibodies — Another rare antibody that may be tested in some cases.
Preparation
No fasting or special preparation is usually required. Tell your doctor about any medications you take, as some can affect the test.
Results and what they mean
Results are reported as positive or negative for each antibody, sometimes with a numerical level. A positive result does not confirm MG by itself, and a negative result does not rule it out; a clinician interprets the results along with your symptoms and other tests. This is general information, not medical advice.
