Mutated Citrullinated Vimentin (MCV) Antibody details
What Mutated Citrullinated Vimentin (MCV) Antibody shows
Vimentin is a structural protein found in many cells, including those in joint tissue. In rheumatoid arthritis, some proteins are chemically changed by citrullination, and the immune system can make antibodies against them. Anti-MCV antibodies target a modified form of citrullinated vimentin and belong to the same family as anti-CCP antibodies. This test is used to help evaluate joint pain and swelling when rheumatoid arthritis is being considered. A positive result supports the diagnosis and may be linked to more active disease, but it can occasionally be positive in other conditions. It is interpreted alongside anti-CCP, rheumatoid factor, inflammation markers and a clinical examination.
Tests that include Mutated Citrullinated Vimentin (MCV) Antibody
This test is used to help diagnose rheumatoid arthritis (RA) by detecting specific antibodies. It's often used alongside other markers like rheumatoid factor and anti-cyclic citrullinated peptide (CCP). While MCV antibody is slightly less specific than CCP, it offers a bit higher sensitivity, improving RA diagnosis by 5-10% when combined with CCP. A positive MCV antibody test also indicates a more severe form of the disease and a greater likelihood of joint damage over time.
