Striated Muscle Antibody Test with Reflex to Titer

The Striated Muscle Antibody Test with Reflex to Titer detects antibodies targeting striated muscle, often linked to autoimmune conditions and paraneoplastic syndromes. Elevated levels may indicate myasthenia gravis, thymoma, or other neuromuscular disorders. Reflex titers help assess antibody concentration, supporting diagnosis, monitoring disease activity, and guiding evaluation of immune-mediated muscle weakness.
