What tests should be done on every ME/CFS patient?

[slysaint]

I spent years trying to figure out what i had before getting the diagnosis, so i'm sure i've covered a lot of it but is there anything thats common/uncommon or similar diseases to rule out or useful tests that every ME/CFS patient should get done to understand or tailor treatments for this condition that i should ask for?
Also what should i be trying to see if it has any effect (if i have the means in the future), i have tried many things but have seen others mentioned across the forum.

you might find the Lucinda Bateman stuff useful; do a search on PR.
