Absolutely and positively can temp. affect testing.

There had been several articles written up about it? But they are no longer available on line.
Thing is, lower skin or body temp slows the nerve conductivity. Thus a ‘normal’ report can be a false report if you’re COLD during the test.
When I get cold, I will rub my affected areas gently to stimulate some extra circulation…. At home when it gets really bad, I’ll use a hair blower on low and gently wave it over the skin to ‘thaw’ it. Parts actually try to turn blue at times! I think the next time I get any nerve testing done? I’m going to bring my own lap robe! Just in case.
Hope this helps.
