Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The RAQoL was developed by Galen Research, the University of Leeds and the Academic Hospital Maastricht, and was first published in 1997. [5] It was the first patient completed quality of life questionnaire that focused on rheumatoid arthritis [6] and is distinct from other questionnaires as it includes physical contact as a dimension of quality of life. [3]
ACR score is a scale to measure change in rheumatoid arthritis symptoms. [1] It is named after the American College of Rheumatology. The ACR score is more often used in clinical trials than in doctor patient-relationships, as it allows a common standard between researchers. Different degrees of improvement are referred to as ACR20, ACR50, ACR70.
Rheumatoid arthritis (RA) is a long-term autoimmune disorder that primarily affects joints. [1] It typically results in warm, swollen, and painful joints. [1] Pain and stiffness often worsen following rest. [1] Most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body. [1]
Laboratory tests (e.g. Erythrocyte Sedimentation Rate, Rheumatoid Factor, Anti-CCP (Anti-citrullinated protein antibody), ANA (Anti-Nuclear Antibody)) X-rays, Ultrasounds, and other imaging methods of affected joints; Cytopathology and chemical pathology of fluid aspirated from affected joints (e.g. to differentiate between septic arthritis and ...
point-of-care testing for rheumatoid arthritis using the rheumachec rapid test. In rheumatology diagnostics, autoantibodies against mutated citrullinated vimentin (anti-MCV) are of prominent diagnostic and prognostic value. [3] Their significance is greater than that of rheumatoid factor.
Rheumatoid factor (RF) is the autoantibody that was first found in rheumatoid arthritis. It is defined as an antibody against the Fc portion of IgG and different RFs can recognize different parts of the IgG-Fc. [ 1 ]
In a comparative study (in 2007), various detection kits had a sensitivity between 69.6% and 77.5% and a specificity between 87.8% and 96.4%. [12] Despite the excellent performance of these immunoassays, for example CCP-assays, they only provide a sensitivity comparable with that of rheumatoid factor (RF). Moreover, analysis of the correlation ...
