Question

Select all that apply.
A) Magnetic resonance imaging (MRI)
B) Alkaline phosphatase (ALP)
C) Human leukocyte antigen-B27 (HLA-B27)
D) Rheumatoid factor (RF)
E) Electromyography (EMG)

Answer 1

Answer: B, C, D

ALP, HLA-B27, and RF are all laboratory tests that are used to diagnose clients with musculoskeletal disorders that can cause an alteration in mobility. ALP is produced by bone and other organs. Increased ALP may indicate bone disease, bone fracture, bone tumors, osteomalacia, Paget disease, and rickets. Decreased ALP may indicate Wilson disease. The presence of HLA-B27 indicates an increased risk ?or ankylosing spondylitis and arthritis. Elevated levels of RF may indicate rheumatoid arthritis, scleroderma, lupus erythematosus, and adult Still disease. MRI and EMG are both diagnostic, not laboratory, tests use to diagnose the cause of alterations in mobility.
