PROVIDER INITIATED TEST - The RNP Antibodies test measures antibodies directed against ribonucleoproteins (RNP), which are components of the cell nucleus involved in RNA processing. These antibodies are commonly associated with mixed connective tissue disease (MCTD) and may also be present in other autoimmune conditions such as lupus or scleroderma.
This test is typically ordered as part of an ANA component or autoimmune evaluation when symptoms such as joint pain, muscle weakness, Raynaud’s phenomenon, fatigue, or unexplained inflammation are present. Results are interpreted alongside other autoimmune markers and clinical findings to support diagnosis and disease classification.
