ACHR ANTIBODIES ACETYL CHOLINE RECEPTOR ANTIBODIES (ACHRAB)

The ACHR Antibodies (Acetylcholine Receptor Antibodies, AChR-Ab) test detects autoantibodies directed against the acetylcholine receptor at the neuromuscular junction by analysing a serum sample using sensitive immunoassay methods. Presence of AChR antibodies is a key laboratory marker used to support the diagnosis of myasthenia gravis and to evaluate possible associations such as thymoma.

This test is recommended for patients with fluctuating skeletal muscle weakness (including ocular symptoms such as ptosis and diplopia), bulbar symptoms, or suspected autoimmune neuromuscular disease; results help clinicians confirm diagnosis, guide decisions on immunotherapy or thymectomy, and prioritise specialist neurology referral. Results should be interpreted alongside clinical examination and electrophysiological studies by a neurologist, and certain treatments (e.g., recent IVIG, plasmapheresis, or immunosuppressants) can affect antibody levels.

• Acetylcholine receptor binding antibodies
• Acetylcholine receptor blocking antibodies

• Fluctuating muscle weakness that worsens with activity
• Unexplained eyelid drooping (ptosis) or double vision (diplopia)
• Speech changes, chewing or swallowing difficulties (bulbar symptoms)
• Suspected myasthenia gravis or to evaluate for thymoma
• Prior to or during neurology work-up to confirm autoimmune cause
