Hi, Rachelandre, and welcome! Well, I'm not a doctor but it looks like they checked you for the Epstein Barr virus. This virus causes mononucleosis (mono) and it has been linked to Chronic Fatigue Syndrome. So it looks like your doctor is running tests to rule out other illness. You see, there are many illnesses that have many of the same symptoms as fibro. Since there are no tests for fibro, they rule out the other illnesses before a diagnosis of fibro is given. If you really want to know, call your doctor. They can totally explain what that test was for and what the results were.
Be sure to check out Fibro 101...the second thread on the forum. There are links to good info about fibro and you will learn a lot there. Good starting links to read are called Symptoms, What Else Could It Be, and A Thorough Explanation of Fibromyalgia.
I'm so glad you found us and joined in. Don't hesitate to ask questions because we are here to help you. I'm looking forward to getting to know you better and I hope to hear more from you soon.
