What's this test for?

This test is ideal if you're experiencing unexplained seizures, sudden confusion, memory problems, or unusual changes in behavior or movement. These symptoms can sometimes be caused by your immune system mistakenly attacking your brain, a condition called autoimmune encephalitis. This panel looks for the specific antibodies behind that kind of reaction so you can understand what might be going on.

What's included in this test?

This panel checks for several different neuronal antibodies at once, since autoimmune encephalitis can involve one or multiple antibodies working together. Testing for a broad group in a single panel increases the chance of catching an antibody that a narrower, single-marker test might miss. If an initial screen is positive, the test automatically reflexes to titer and line blot testing to pinpoint exactly which antibody is present.

What happens after I get my results?

Your results will appear in your online account, with each antibody result explained along with what a normal versus abnormal finding looks like. If any antibody comes back positive, the report will describe the reflex titer or line blot follow-up results so you have the full picture in one place. Because these results can point to a serious underlying issue, anyone with a positive or unclear result should seek prompt medical care to discuss next steps. You can download a standard lab report anytime and use the trends feature to track any future retests over time.

How can I naturally support brain and immune health?

While antibody-driven encephalitis needs medical evaluation, you can support your overall brain and immune health with consistent sleep, regular movement, and a diet rich in omega-3s, leafy greens, and antioxidants. Reducing chronic stress and avoiding excessive alcohol also helps keep your immune system balanced. These habits won't replace treatment if antibodies are found, but they support your body while you sort out next steps.

When will I get my results?

Results are typically ready within about 7 days of your sample being collected, since this panel may include automatic reflex testing to titers or line blot confirmation if the initial screen is positive. That extra step can add a little time compared to a simple single-marker test, but it gives you a much clearer answer. You'll get a notification as soon as your results are posted to your account.

Who should consider this test?

This test is worth considering if you or a family member has had a sudden, unexplained change in mental function, new seizures, or rapid-onset psychiatric symptoms without a clear cause. It's also useful if other common causes like infection or metabolic issues have already been ruled out. People with a known cancer diagnosis experiencing new neurological symptoms may also want this panel, since certain cancers can trigger these antibodies.

What symptoms indicate I may need this test?

Common symptoms include new or worsening seizures, sudden confusion or memory loss, hallucinations, unusual movements, or a fast change in personality or behavior. Some people also experience problems with speech, sleep disturbances, or a rapid decline in normal thinking abilities. If these symptoms come on quickly and don't have an obvious explanation, this panel can help identify an autoimmune cause.

What is autoimmune encephalitis and why does it matter?

Autoimmune encephalitis happens when your immune system creates antibodies that mistakenly attack proteins on your brain cells, causing inflammation and disrupting normal brain function. It matters because, unlike many other causes of confusion or seizures, this condition can often improve significantly once the responsible antibody is identified and addressed. Catching it early can make a real difference in how well and how quickly someone recovers.

What does a positive antibody result mean?

A positive result means one or more neuronal antibodies were detected in your blood, which suggests your immune system may be attacking brain tissue. The reflex titer tells you how much antibody is present, which can help gauge how active the immune response is. Any positive result should be treated as urgent, and you should seek medical care right away to discuss appropriate next steps.

What should I do if my results are abnormal?

If your results show a positive antibody, don't wait — seek medical care promptly, especially if you're having ongoing seizures, worsening confusion, or rapid changes in behavior. Bring your downloadable lab report with you so the details, including the titer and line blot findings, are available to whoever evaluates you. Early action tends to lead to better outcomes with this type of condition.
