The AChR (acetylcholine receptor) antibody test is a blood test used to diagnose Myasthenia Gravis (MG), an autoimmune neuromuscular disease. It measures the level of AChR antibodies in the blood, which are antibodies that attack the connections between nerves and muscles, causing muscle weakness. Here's a more detailed explanation: What it tests: The test measures the concentration of AChR antibodies in the blood. Why it's ordered: Doctors may order this test if a patient is experiencing symptoms that suggest Myasthenia Gravis, such as drooping eyelids, double vision, difficulty swallowing, or muscle weakness. How it helps diagnose MG: The presence of AChR antibodies in the blood is a key indicator of MG, helping to confirm the diagnosis and differentiate it from other conditions that may cause similar symptoms. How it's performed: The test involves a simple blood draw, and the blood sample is then analyzed in a lab to determine the level of AChR antibodies. Normal results: Normally, there are no or very low levels of AChR antibodies in the blood. When it's ordered: The test may be ordered during diagnosis, to monitor the progression of MG, to assess the effectiveness of treatment, or to evaluate the possibility of antibody transmission from a pregnant woman to her baby. Other uses: The test can also help differentiate between congenital and acquired forms of MG. In essence, the AChR antibody test is a valuable tool for diagnosing Myasthenia Gravis and monitoring its course. In Pimpri Chinchwad Pune Exploring Truth...
