Acetylcholine Receptor (AChR) Antibody, Serum Test Overview

What is the Acetylcholine Receptor (AChR) Antibody, Serum Test?

The AChR Antibody, Serum Test measures the presence of antibodies against acetylcholine receptors in the blood. These antibodies interfere with communication between nerves and muscles, which can result in symptoms such as muscle weakness, fatigue, drooping eyelids, or difficulty swallowing.

This test is primarily used to help diagnose autoimmune neuromuscular conditions, such as myasthenia gravis, where the body’s immune system mistakenly attacks healthy neuromuscular junctions. Elevated antibody levels indicate an autoimmune response, while negative results may help rule out the condition.

Understanding AChR antibody levels is essential because early diagnosis allows prompt treatment to reduce symptoms and prevent progression. Monitoring antibody levels over time can also guide treatment effectiveness. This test is valuable for patients experiencing unexplained muscle weakness, for monitoring known autoimmune neuromuscular disorders, or before planning specific treatments.

Why Take the Acetylcholine Receptor (AChR) Antibody, Serum Test?

This test is recommended if you:
