Anti cyclic citrullinated peptide anti ccp is an antibody present in most rheumatoid arthritis patients. See connective tissue diseases cascade ctdc in special instructions.

What Is The Anti Cyclic Citrullinated Peptides Anti Ccp Blood Test
Approximately 70 of ra patients are positive for anti ccp igg while only 2 of random blood donors and control subjects are positive.
Cyclic peptide igg. A synthetic circular peptide containing citrulline called ccp igg cyclic citrullinated peptide has been found to be better at discriminating rheumatoid arthritis patients from patients with other diseases such as hepatitis c infection. Draw blood in a plain red top tubes or a serum gel tubes. The presence of ccp antibodies when considered in conjunction with other laboratory and clinical findings is an aid in the diagnosis of rheumatoid arthritis ra.
A cyclic citrullinated peptide ccp antibody test may be ordered along with or following a rheumatoid factor rf test to help diagnose rheumatoid arthritis ra and to assess the severity and probable course of the disease. These autoantibodies may be present in the preclinical phase of disease are associated with future ra development and may predict radiographic joint destruction. Levels of anti ccp can be detected in a patient through a blood test.
A positive anti ccp test result can be used in conjunction with other blood tests imaging tests and physical examinations to reach a rheumatoid arthritis diagnosis. Synthetic cyclic citrullinated peptide ccp variants also react with anti filaggrin autoantibodies and serve as the substrate for detecting anti ccp antibodies serologically. Anti cyclic citrullinated peptide anti ccp igg antibodies are present in about 69 83 percent of patients with rheumatoid arthritis ra and have specificities of 93 95 percent.
Spin down and send 1 ml of serum refrigerated or frozen in plastic vial. Most studies of anti ccp antibodies demonstrated that these autoantibodies have much improved specificity for ra compared to rf3nbsp.
