ANTI CYCLIC CITRULLINATED PEPTIDE; ANTI CCP

Anti-CCP is a specific antibody that targets cyclic citrullinated peptides, proteins that have undergone a chemical modification known as citrullination. The presence of anti-CCP antibodies is a highly specific marker for rheumatoid arthritis (RA). While not all patients with RA will test positive for anti-CCP, a positive test can significantly increase the likelihood of a diagnosis. Anti-CCP is often used in combination with other diagnostic tests, such as rheumatoid factor (RF), to confirm the presence of RA and to predict disease progression.
