Hi, chiab. Do you mind saying what other tests they ordered?

That test is not specific to MG, but can show up in MG patients.

Do the doctors suspect MG?

You can have more than one thing going on at once, too. Many of us have. So if a doctor isn't being thorough, they might miss something.

Do you have ptosis? Muscle weakness?

Anything you could add might help us to help you! Thanks.
