Welcome, and it's completely understandable to feel frustrated — being dismissed by doctors when you're struggling is exhausting and disheartening. You're not alone in this experience, and your concerns are valid.
Here's something really important to know: a negative AChR antibody test does NOT rule out MG. There are actually multiple antibody types that can indicate MG:
- AChR antibodies — present in about 85% of MG cases
- MuSK antibodies — found in up to 40% of AChR-negative MG patients
- LRP4 antibodies — found in a small percentage of cases
- Seronegative MG — where no antibodies are detected at all, but MG is still present One MGteam member shared that their diagnosis wasn't confirmed until an EMG (electromyography) test was done, even though blood work came back negative. Another said it took three years to get diagnosed, with patience being key.
Beyond blood tests, doctors can use other tools to diagnose MG:
- EMG (electromyography) — measures nerve and muscle communication
- Repetitive nerve stimulation — checks how muscles respond to nerve signals
- Imaging — CT or MRI scans to check the thymus gland The most important next step would be requesting a referral to a neurologist who specializes in MG. A general neurologist or non-specialist may not be familiar enough with the full diagnostic process. The Myasthenia Gravis Foundation of America (MGFA) has resources to help find qualified MG specialists near you.
Don't give up — getting a proper evaluation from the right specialist can make all the difference.
