Diagnostic sensitivity refers to the probability of obtaining a positive result for a patient with a given disease.A number of laboratory tests may be used to make a diagnosis of RA, including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), and anti-nuclear antibodies (ANA).Although most of these serum tests are nonspecific for rheumatoid arthritis, the RF assay is positive in about 70% to 90% of patients with this disease-a high diagnostic sensitivity.
