Precision testing study for myasthenia gravis in China
Part of Brain & nervous system, Cancer, Immune system & allergy clinical trials.
This study follows people with suspected or confirmed myasthenia gravis (a condition that causes muscle weakness that gets worse with use). It uses several specialized nerve and antibody tests to make a more precise diagnosis and tracks you over time to see how well these methods work.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have muscle weakness that tends to come and go, gets worse with use, and improves with rest
- Your symptoms fit one of these test patterns: low-frequency repetitive nerve stimulation shows more than a 10% drop, or high-frequency repetitive nerve stimulation does not show a meaningful more-than-10% rise
- OR you have a positive blood test for anti–AChR or MuSK antibodies
- OR you have a positive neostigmine test (a medication test doctors use to check for myasthenia gravis)
- You can understand, sign, and follow the informed consent, and you agree to attend follow-up visits reliably
