I haven’t heard that term before, but I think I’ve had all those blood tests. Did your doctor say exactly which tests? Between my neurologist, rheumatologist, endocrinologist, dermatologist and gastroenterologist, I think they have covered all the tests that would indicate a problem….colonoscopy to rule out tumors, brain MRI, etc. Insurance covered them. The only other tests I haven’t had are spine scans and biopsies. My understanding is that we were trying to rule things out.
