Test Description for Mutated Citrullinated Vimentin (MCV) Antibody:
Name: Mutated Citrullinated Vimentin (MCV) Antibody Test
Also Known as: anti-MCV,RA,Rheumatoid arthritis
Purpose: The Mutated Citrullinated Vimentin (MCV) Antibody test is utilized as a secondary marker in the diagnosis of rheumatoid arthritis (RA). It serves to complement primary markers like rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP) antibodies.
Test Significance: Anti-MCV antibodies are part of a group of anti-citrullinated protein antibodies (ACPAs) that target mutated citrullinated vimentin. While the MCV antibody test is slightly less specific than the anti-CCP test, it offers marginally higher sensitivity. Including an MCV antibody test alongside the CCP test can enhance the sensitivity of RA diagnosis by an additional 5-10%.
Clinical Relevance: The presence of MCV antibodies is not only indicative of RA but is also correlated with a more aggressive disease course. Patients who test positive for MCV antibodies often exhibit more severe RA symptoms and show greater radiological progression over time.
Testing Methodology: The detection of MCV antibodies is typically conducted via immunoassays that quantify the level of these antibodies in the patient's blood.
Interpretation: Positive results for MCV antibodies may necessitate further investigation and can be a significant factor in the management and treatment planning of rheumatoid arthritis, due to its association with more severe disease prognosis.
Reference Range(s)
<20 U/mL
Note: The test is most effective when used in conjunction with other RA markers, and results should be evaluated by a healthcare professional within the broader context of clinical findings and patient history.
