Doctors do not use lab tests to diagnose fibromyalgia. The results of lab tests done on people with fibromyalgia should be normal unless another condition is present.
You may have lab tests to rule out other diseases or to find out whether you have another disease in addition to fibromyalgia. Fibromyalgia may occur along with other joint and muscle (rheumatic) diseases, such as rheumatoid arthritis. Finding these other conditions is important, because they may need different treatment.
