What this laboratory test evaluates
Cyclic Citrullinated Peptide (CCP) Antibody (IgG)
This test is a specialized test that helps in the diagnosis of Rheumatoid Arthritis (RA). It detects the presence of specific antibodies (CCP IgG) in the blood, which are more common in people with RA compared to other conditions like hepatitis C. This test is part of the criteria used to classify Rheumatoid Arthritis, along with other tests such as rheumatoid factor, C-reactive protein, and erythrocyte sedimentation rate (ESR). About 70% of RA patients test positive for Anti-CCP IgG, making it a crucial marker for the disease, whereas it's rarely found in healthy individuals or those with other diseases.
What patients is this test right for?This test is particularly useful for individuals suspected of having Rheumatoid Arthritis, especially when symptoms like joint pain, stiffness, and swelling are present.
What type of sample is required for this test?1 mL serum.
