FAQ
Frequently asked questions
What is Myasthenia Gravis?
Myasthenia Gravis is a chronic autoimmune disorder where the immune system mistakenly attacks the body's own tissues. In this case, it targets the communication points between nerves and muscles, leading to muscle weakness.
Are there other types of MG antibody tests?
Yes, while AChR binding antibodies are the most common, other antibodies like MuSK antibodies can also be associated with Myasthenia Gravis. Your clinician will determine which tests are most appropriate for your situation.
How accurate is the AChR antibody test?
This test is highly sensitive for Myasthenia Gravis, detecting these specific antibodies in the majority of individuals diagnosed with the condition. However, a negative result does not completely rule out MG, especially if symptoms are present.
Can this test be done at home?
This test requires a blood draw performed by a trained healthcare professional. It cannot be collected at home, but you may be able to visit a local lab for sample collection after receiving an order from your clinician.
