As always, this page is work in progress and currently just a scratch pad – and not very up to date.
There are currently no tests for ME/CFS like there are for e.g. diabetes. What can be done is rule out other diseases (like hypothyroidism) on the one hand. On the other hand there are tests that can give you a indication if you have clinical symptoms (like cortisol-profile or NK-cell function).
