Yes! While about 85% of people with MG have positive AChR antibodies, approximately 15% test negative. This is completely normal and doesn't make your MG diagnosis any less valid.
If you test negative for AChR antibodies, your doctor may test for other antibodies like MuSK, which is found in 30-40% of people who are AChR Show Full Answer
I have no antibodies. No matter how many blood tests or vaxx I take.
I am also seronegative. I was extremely lucky to get in with a neurologist who has experience with MG especially since I had no clue what was wrong with me & neither did my GP or rheumatologist.
Hi Lise! I am totally seronegative; I've tested negative for ALL the antibodies. We're part of a smaller 'community' than MG warriors in general, as the AI-generated answer indicates. Sadly, I think it's not uncommon for doctors, and even neurologists in some cases, who haven't worked much with myasthenia patients to rule out MG as a diagnosis when the tests come back negative. But highly informed physicians with experience treating MG patients will look past the antibody tests and make a diagnosis based on symptoms and (in my case) response to treatment. If you're antibody negative and still have a diagnosis of MG, you must have found one of the good, open-minded ones!
Hope you're doing well and that the week ahead is a good one! ❤️wm
