What's this test for?

This test is ideal if you're experiencing symptoms of autonomic nervous system trouble, such as unexplained dizziness when standing, digestive issues, abnormal heart rate, blood pressure swings, or excessive sweating. It helps identify whether an autoimmune condition called Autoimmune Autonomic Ganglionopathy (AAG) may be causing these problems. Finding this out early matters because AAG can sometimes be linked to an underlying tumor, and treating the root cause can lead to real improvement.

What happens after I get my results?

Your results will be available in your account, with each value's normal range clearly explained so you understand exactly where you stand. If your antibody levels come back elevated, the report will guide you on next steps, which may include seeking further evaluation given the connection between this antibody and certain tumors. You can download a standard lab report directly from your account at any time, and if you retest in the future, you'll be able to track changes over time using the trends feature.

What's included in this test?

This test measures the Acetylcholine Receptor Ganglionic (Alpha 3) Antibody (G-nAChR autoantibody), a specific marker that targets a receptor involved in communication within your autonomic nervous system, the part of your body that controls things like heart rate, digestion, and blood pressure without you thinking about it. Elevated levels of this antibody can point to an autoimmune process attacking this system, which matters because it can explain otherwise mysterious symptoms and, in some cases, signal an underlying tumor that needs attention.

What symptoms indicate I may need this test?

Consider this test if you have unexplained fainting or dizziness upon standing, chronic nausea or bloating without a clear digestive cause, abnormal sweating patterns, blurred vision, or a racing heart that doesn't match your activity level. These can all be signs of autonomic nervous system dysfunction. If these symptoms have been going on for a while without an answer, this test can help narrow down the cause.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. This test uses a specialized method, so it takes a bit longer than routine bloodwork. You'll be notified as soon as your results are posted to your account.

Who should consider this test?

People dealing with ongoing, unexplained autonomic symptoms—like lightheadedness, digestive slowdowns, or irregular heart rate—that haven't been explained by other testing should consider this test. It's also useful for anyone with diabetic nerve damage or postural tachycardia syndrome (POTS) whose symptoms seem more severe or unusual than typical. This test can help clarify whether an autoimmune process is behind the symptoms.

What is Autoimmune Autonomic Ganglionopathy and why does it matter?

Autoimmune Autonomic Ganglionopathy, or AAG, happens when your immune system mistakenly attacks a receptor that helps control your autonomic nervous system, the system that runs automatic body functions like heart rate and digestion. It matters because AAG is treatable when identified early, and in some cases it's connected to hidden tumors like small-cell lung cancer or thymoma. Catching it means you can pursue treatment that may significantly improve your symptoms.

What does a high antibody result mean?

A high result suggests your immune system may be producing antibodies that interfere with normal autonomic nervous system function, supporting a diagnosis of AAG. Because this condition has been linked to certain tumors, a high result is often followed by additional imaging or evaluation to rule out an underlying cause. The good news is that once identified, this condition often responds well to targeted treatment.

How often should I retest?

Retesting isn't usually done on a routine schedule for this type of specialized antibody test. It's generally used once to help clarify a diagnosis, though you might retest later if you're monitoring treatment response or if your symptoms change significantly. Tracking any repeat results over time is easy using the trends feature in your account.

What should I do if my results are abnormal?

If your antibody levels come back elevated, don't panic—this is a starting point for understanding your symptoms, not a final diagnosis on its own. Keep a record of your symptoms and consider follow-up evaluation to check for any underlying causes, since early action tends to lead to better outcomes. If you experience severe symptoms like fainting, chest pain, or difficulty breathing, seek medical care right away.
