I have hyperparathyroid orginally due to vit D defieciency but now it wont normalize even when my levels are in the normal range. I know all the differences I feel when this hormone is elevated so it makes sense to me that this cold affect accurate tests like blood for MG and maybe even EMGs. Does anyone know. This question came to me as I was reading pingpongmans AChR question and responses this morn.

Also what is everyones experience with doctors knowledge on the correct way to get good SFemg and emg tests done? When I went to may I was surprised that it was very very important to them that I be warm. I asked why the room was warm and why I was being asked about how warm I was. They said it is important to test accurancy. I have found this stated in online emg tech manuals for emgs and medical research material. I asked my neuro about this as I have never been tested in summer when I am worse with the warming thing taken into consideration. When Mayo did mine they were negative per se but showed myotonic discharges which I also found can indicate a cold muscle. It was December in the midwest when this test was done and I had travel north and it was colder so the morning I went I was noticelably stronger and was concerned the test would be blown.
