Women and men living with fibromyalgia do not have characteristic or consistent abnormalities on laboratory testing. However, routine laboratory and imaging studies are important to help rule out diseases with similar manifestations and to assist in diagnosis of certain inflammatory diseases that frequently coexist with fibromyalgia. These are the lab tests commonly checked by physicians treating fibromyalgia patients: CMP, CBC, Urinalysis, TSH, Vitamin D & B-12, Iron/TIBC, Magnesium in RBC, ESR, CPK and Ferritin.

This osteoporosis panel includes:

• Serum total calcium, albumin (to calculate albumin adjusted calcium) and phosphorus as part of a CMP panel to detect conditions associated with hypercalcemia such as primary hyperparathyroidism or hypocalcemia and consequent secondary hyperparathyroidism causing bone loss
• Serum creatinine and estimated glomerular filtration rate (GFR) as part of the CMP panel are useful to detect renal failure which can affect bone health. 
• Serum alkaline phosphatase (ALP) as part of a CMP panel. ALP measurement is useful to detect conditions including Paget's disease, metastatic bone disease and osteomalacia, etc.
• Vitamin D nutrition should be determined by measuring serum 25-hydroxy vitamin D [25(OH)D]. Although there is controversy about the optimum level of 25(OH)D for bone health; while 50 nmol/L is considered acceptable
• Parathyroid Hormone (PTH) measurement would be required if serum calcium is abnormal, to help investigate the cause of the calcium abnormality.
• Ultra-sensitive Estradiol. Low estradiol in men and women has been linked to bone loss.
• Phosphorus. An increased phosphorus with decreased calcium suggests either hypoparathyroidism or renal disease. A decreased phosphorus and an increased calcium suggests hyperparathyroidism or sarcoidosis. When both calcium and phosphorus are decreased diagnostic considerations include malabsorption, vitamin D deficiency and renal tubular acidosis. Increased phosphorus and normal or increased calcium suggests Milk-alkali syndrome or hypervitaminosis D.
