Moreover, analysis of the correlation of anti-CCP antibody titre with RA disease activity yielded conflicting results. [13] [14] However, novel test systems utilizing ACPA have been developed. Citrullinated vimentin is a very promising autoantigen in RA, and a suitable tool for studying this systemic autoimmune disease. Vimentin is secreted and ...
When RA is clinically suspected, a physician may test for rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPAs measured as anti-CCP antibodies). [81]: 382 The test is positive approximately two-thirds of the time, but a negative RF or CCP antibody does not rule out RA; rather, the arthritis is called seronegative, which ...
Anti-MCV antibodies are a member of the ACPA family, a group of the so-called antibodies to citrullinated protein/peptide antigens. Rheumatoid arthritis is an autoimmune disorder. Detection of specific autoantibodies (antibodies directed against the body’s own tissue) such as rheumatoid factors and ACPAs may provide indication of the disease.
High levels of rheumatoid factor (in general, above 20 IU/mL, 1:40, or over the 95th percentile; there is some variation among labs) occur in rheumatoid arthritis (present in 80%) and Sjögren's syndrome (present in 50-70% of primary forms of disease). [11] The higher the level of RF the greater the probability of destructive articular disease.

Antibodies are generated randomly, so the immune system has a low chance of generating an antibody capable of weakly binding to the assay by coincidence. More rarely, individuals who have recently had some vaccines or who have certain autoimmune conditions can temporarily test falsely seropositive. Due to the possibility of false positives ...

Thrombotic thrombocytopenic purpura (TTP) is a blood disorder that results in blood clots forming in small blood vessels throughout the body. [2] This results in a low platelet count, low red blood cells due to their breakdown, and often kidney, heart, and brain dysfunction. [1]
