• Seronegative myasthenia gravis: share your experience

    Posted by Jodi on November 12, 2025 at 7:31 am

    Being seronegative can make the path to diagnosis and treatment even more confusing and complicated. Without positive antibody test results, it may take longer to find the right doctor, obtain a validated diagnosis, or start treatment.

    • If you’re living with seronegative MG, what has your experience been like?
    • How did doctors approach your symptoms and diagnosis?
    • How long did it take for you to feel like you were in good hands?

    Being Seronegative has been an extremely challenging experience!!!! Doctors do not believe you have the diagnosis even with a positive single fiber EMG. It took years of getting an incorrect diagnosis prior to me finding a seronegative friendly doctor. I was able to get my thymectomy which helped so very much, however many others are not allowed due to being seronegative. I have CVID, which means I do not make enough IGG, or IGA. I have 6 autoimmune diseases, and I am negative for all because I do not make enough immunoglobulins for the tests to be accurate. Others like me are suffering and we cannot get the approved medications because our blood tests are negative even though we have the disease. More doctors need to be educated in the understanding that clinical testing other than blood tests should be accepted. The FDA needs to adjust the clinical trial inclusion criteria to allow seronegative patients participate in trials so that we can get the medications that we need. It is such a broken process.

    Seronegative MG can lead people through a complicated journey filled with misdiagnosis, difficulty finding the right provider, and barriers to treatment.

    Many individuals have to put in extra effort to prove their symptoms repeatedly, even when other tests clearly indicate MG. Others reading this might see their own stories in what you’ve shared, and it adds an important voice to the conversations about seronegative MG.
