I was never given a test I had a very smart doc who concluded the blood cells EBV and tiredness not going away as CFS.I was believed back in 2003. Even Fibromyalgia they diagnosed. Have seen multiple pain docs who agree and 2 Rheumys. I wish I had this back then, it would have led to a faster diagnoses as I searched the internet and she searched for these symptoms.
