Hi, I have some questions about blood tests for MG.

I have been going to my opthamologist quite a bit lately about double vision (really kind of seeing a shadow just slightly behind the image) and blurriness.

I have had prisms in my glasses for about two years now. In August of '08 (when I resumed teaching) I noticed that I was once again seeing double and have blurry vision. I finally got back into the Dr. in January and she changed my RX. The problems got better until about May when it started again. I again returned to the Dr. who decided to have me try these temporary prisms.

At that time the Dr. decided to run the achr test which came back elevated. The lab suggested two other tests which were also blood tests. They came back negative. The Dr. said that the "jury is still out on whether I have MG or not."

I do not know what these other two tests were and I do not know at this time if I have MG or not. Can you help me understand what this means?
