About the Myasthenia Gravis (MG) Lab Test - AChR Antibody Testing
An acetylcholine receptor binding antibody test checks the blood for autoantibodies that target the acetylcholine receptor, a protein involved in nerve-to-muscle signaling. It is used as a laboratory aid in the evaluation of myasthenia gravis, a condition that causes muscle weakness. The test is ordered when a healthcare provider suspects myasthenia gravis or wants to support an existing evaluation. It is one piece of a broader assessment and is not a stand-alone diagnosis. Results are interpreted alongside symptoms, physical examination, and other testing.
Who this test may be right for
- People with muscle weakness that worsens with activity
- Individuals with drooping eyelids, double vision, or difficulty swallowing or speaking
- People whose healthcare provider suspects myasthenia gravis
- Those being evaluated for a neuromuscular junction disorder
- Individuals whose healthcare provider wants to support an existing myasthenia gravis assessment
What this test measures
- Acetylcholine receptor (AChR) binding antibody An autoantibody directed against the acetylcholine receptor; used to help evaluate myasthenia gravis.
Before your visit
- No fasting is required for this blood test
- A standard blood draw is used to collect the sample
- Tell the lab about any medications you take
- Follow any specific instructions supplied with your test order
Understanding your results
A positive AChR binding antibody result can support the evaluation of myasthenia gravis, while a negative result does not rule it out, because some people with the condition do not have this antibody detected. The result is interpreted with symptoms and other testing. A positive or negative result alone is not a diagnosis. Discuss your AChR binding antibody result with a healthcare provider, who can explain what it means in the context of your overall evaluation.
