Anyone know about P100 latency times in a VEP? I know each lab has their own threshold value but my understanding is “normal” normal is 100ms. The ones I saw on the screen today ranged from 113-119.

I know it’s a technical q and my dr will have the report soon enough anyway....but curiousity is killing me!

Sorry Qt314grl but I have not had or know about VEP.

I had tests last April and was "Normal." I've got the doc report around here somewhere will try find it and have more info. I was fortunate to have a great, but lengthy procedure. The technician was a young lady and made it all fun for 5 hrs!

Hmmm, maybe I did a different test? I just had to sit and stare at a red dot in the middle of a moving checkerboard pattern. It took about 20 min once I had all the electrodes on my head.

I also did nerve conduction studies yesterday which did take longer but not more than an hour or so.
