Lab Test and Clinical Procedures (Ch 15) Flashcards
antinuclear antibody test
detects an antibody present in serum of patients with systemic lupus erythematosus and other autoimmune diseases
arthrocentesis
surgical puncture to remove fluid from the joint space
arthrography
x-ray imaging of a joint after injection of contrast material
arthroplasty
surgical repair of a joint; total hip replacement and total knee replacement are examples
arthroscopy
visual examination of the inside of joint with an endoscope
bone density test
low-energy x-ray absorption in bones of the spinal column, pelvis, and wrist; used to measure bone mass; also called dual-energy x-ray absorptiometry
bone scan
uptake of a radioactive substance is measured in bone
discography
x-ray images of cervical or lumbar intervertebral discs after injection of contrast material into the interior of the disc
electromyography
recording the electrical activity of a muscle tissue
erythrocyte sedimentation rate
measures the time it takes for erythrocytes to settle to the bottom of a test tube; useful in detection of inflammatory disorders such as rheumatoid arthritis
muscle biospy
removal of muscle tissue for microscopic examination to assess for abnormalities or disease
rheumatoid factor test
serum (blood minus clotting proteins and cells) is tested for the presence of an antibody found in many patients with rheumatoid arthritis
serum calcium
measurement of calcium level in serum (blood minus clotting proteins and cells)
serum creatine kinase
measurement of the enzyme creatine kinase in serum; increased levels occur in muscular dystrophy, polymyositis, rhabdomyolysis, and traumatic injuries
uric acid test
measurement of uric acid in serum; high levels are associated with gouty arthritis
