What are the normal tests for fibromyalgia they do?

Rule out other stuff: Fibromyalgia is a 'diagnosis of exclusion' which means that the blood tests done during the work up of fibromyalgia are to rule out other possible diagnoses, such as lupus, rheumatoid arthritis, vitamin deficiency, & others. I often check a sed rate (esr), rheumatoid factor (rf), vitamin d and b levels, and thyroid function. In special cases i might check an ANA or other rheumatologic tests.

Clinical exam: Clinical examination by a knowledgeable physician. Tests rule out other entities, but do not diagnose fibromyalgia. Tsh is valuable, as hypothyroidism can mimic fibromyalgia.

Palpation: ? re tests to prove fibromyalgia (FM). The only test used to "rule in" FM is a standardized palpation of several anatomical loci to observe for pain in at least 11 of 16 points. All other tests, including imaging studies & chemical & other analyses of body fluids, are to "rule out" other possible disorders explanatory for the patient's symptoms, which should include both upper & lower back pain.
