Collagen Type II Antibody

About Test

The Collagen Type II Antibody test is a blood test used to diagnose autoimmune diseases, such as rheumatoid arthritis, that affect the joints. Collagen Type II is a protein found in the cartilage of joints, and in autoimmune diseases, the body's immune system mistakenly attacks and damages the joint tissues, including the collagen. The test measures the level of antibodies directed against collagen Type II in a person's blood. Elevated levels of these antibodies indicate that an autoimmune reaction is occurring and can help diagnose rheumatoid arthritis and other joint-related autoimmune diseases. The test results, along with other clinical information, can guide further medical evaluation and treatment decisions.
