Achr Antibody Test

The Acetylcholine Receptor (AChR) Antibody Test is a diagnostic blood test used to assess the presence of antibodies against acetylcholine receptors in the neuromuscular junction. These receptors play a crucial role in transmitting signals from nerves to muscles, and when these receptors are compromised, it can lead to muscle weakness and fatigue.

This test is vital for diagnosing conditions like Myasthenia Gravis (MG), a neuromuscular disorder that causes muscle weakness and fatigue. Detecting AChR antibodies helps confirm the diagnosis and guides treatment decisions. Additionally, it can distinguish between different subtypes of MG.

Individuals experiencing unexplained muscle weakness, double vision, drooping eyelids, or difficulty in motor tasks should consider this test. Those with a family history of MG or related autoimmune disorders may also benefit from it.

A small blood sample is taken, and the serum is tested for the presence of AChR antibodies. The results are usually available within a few days.
