Anti U1RNP

Anti U1RNP


The Anti-U1RNP test measures antibodies in your blood that target U1 ribonucleoprotein, a substance found in the body’s cells. Elevated levels may be associated with autoimmune conditions such as Mixed Connective Tissue Disease (MCTD), lupus, or other connective tissue disorders. This test is usually recommended if you have symptoms like joint pain, muscle weakness, skin changes, or unexplained inflammation. It may also be used to help differentiate between different autoimmune conditions.
