What's this test for?

This test is ideal if you're experiencing muscle weakness that gets worse with activity and improves with rest, drooping eyelids, double vision, or trouble chewing, swallowing, or speaking. These symptoms can point to Myasthenia Gravis, a condition where your body's immune system interferes with the connection between your nerves and muscles. This test checks for the antibodies that cause this problem.

What's included in this test?

This test measures acetylcholine receptor antibodies, the specific immune markers linked to Myasthenia Gravis. These antibodies matter because they attack the connection point between your nerves and muscles, which is what causes the muscle weakness and fatigue seen in this condition. Detecting them helps confirm whether this immune reaction is behind your symptoms.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a normal versus abnormal range looks like for this antibody test. If your results come back positive, the report will explain what that means and suggest reaching out for further evaluation, since Myasthenia Gravis symptoms can sometimes escalate quickly. You can download a standard lab report from your account at any time, and if you retest in the future, the trends feature lets you track any changes over time.

How can I naturally support muscle and nerve health?

While antibody-related muscle weakness isn't something you can fix with lifestyle changes alone, supporting your overall muscle and nerve health can help you feel your best. Getting enough rest, eating a balanced diet with adequate protein, and avoiding overexertion can reduce fatigue-related flare-ups. Managing stress and avoiding known triggers like certain medications or illness can also help keep symptoms more stable.

When will I get my results?

Results for this test are typically ready within about 7 days of your lab visit. Once ready, they'll be uploaded directly to your account where you can view and download them. You'll be able to see your antibody levels along with a clear explanation of what they mean.

Who should consider this test?

This test is a good fit for anyone noticing muscle weakness that worsens with repeated use and improves with rest, especially if it affects the eyes, face, or throat muscles. It's also useful for people who've already been told they might have a neuromuscular issue and want a specific antibody check. If you have a family history of autoimmune conditions and are noticing unexplained muscle fatigue, this test can help clarify what's going on.

What symptoms indicate I may need this test?

Common signs include drooping eyelids, blurred or double vision, slurred speech, trouble swallowing, and weakness in your arms, legs, or neck that gets worse throughout the day. Some people also notice their muscle weakness improves after resting. If these symptoms sound familiar, this antibody test can help identify whether Myasthenia Gravis is the cause.

What does a positive antibody result mean?

A positive result means your body has produced antibodies that attack the receptors your muscles need to receive signals from your nerves. This is strong evidence pointing toward Myasthenia Gravis, especially if you're also having muscle weakness symptoms. About 80% of people with this condition (excluding cases limited to the eyes) test positive for these antibodies, so a positive result is quite meaningful.

What does a negative antibody result mean?

A negative result means these specific antibodies weren't found in your blood sample, which makes Myasthenia Gravis less likely but doesn't rule it out completely. About 20% of people with this condition, particularly those with eye-only symptoms, don't have detectable antibodies. If your symptoms continue despite a negative result, further testing may be worth considering.

What should I do if my results are abnormal?

If your results come back positive, it's a good idea to seek further evaluation soon, since Myasthenia Gravis symptoms can sometimes progress and affect breathing or swallowing in more serious cases. In the meantime, avoid overexertion, get plenty of rest, and pay attention to any new or worsening symptoms. If you experience sudden difficulty breathing or swallowing, seek emergency medical care right away.
