Question | Answer |
---|---|
Determines if the disorder is inflammatory or noninflammatory | ESR and C-reactive protein |
Detects antibodies present with rheumatoid arthritis | RF (rheumatoid factor) |
Evaluates for anemia, infection,or inflammation | CBC (Complete Blood Count) |
May indicate bone tumor or healing fractures | Elevated alkaline phosphatase level or Increased Serum phosphorous level |
May indicate Paget's disease (a disorder characterized by excessive bone destruction and disorganized repair) and metastatic cancer | Elevated acid phosphatase level |
May indicated osteomalacia(rickets), osteoporosis and bone tumors | Decreased Serum Calcium |
May indicate gout | Elevated Serum Uric Acid Levels |
May indicate autoimmune disorders such as lupus erythematosus | Elevated AntiNuclear Antibody Level (ANA) |
Must be NPO for 6-8 hrs, monitor kidney functions (do BUN before and after due to contrast), and check allergy to iodine or shellfish | CT |
NO METALS in body (defibulators, pacemakers, jewelry) and check if patient is claustrophobic | MRI |
Internal inspection of a joint using an arthroscope; most common for knee | Arthroscopy |
Aspiration of synovial fluid. May be done to alleviate discomfort caused by excessive accumulation in the joint space or to inject a drug such as a corticosteriod | Arthrocentesis |
Radiographic exam of a joint (usually the shoulder or knee) with the use of a contrast medium. | Arthrogram |
Estimates bone density. Wrist, hip, and spine to determine bone mineral density. | Bone Densitometry |
Uses intravenous injection of a radio-nuclide to detect the uptake of the radioactive substance by the bone. Detects metastatic bone lesions, fractures, and certain types of inflammatory disorders. Taken up in areas of increased bone metabolism. | Bone Scan |
Test the electrical potential of the muscle and nerves leading to the muscle. It is used to differentiate muscle and nerve problems. | Electromyography |
Detects levels of uric acid and calcium excretion | 24 hour urine |
Synovial fluid is aspirated and examined to diagnose disorders such as arthritis. | Synovial Fluid Analysis |
