What's this test for?

This test helps if you're experiencing unexplained behavioral changes, confusion, seizures, memory problems, or psychosis that came on somewhat suddenly. These symptoms can sometimes be caused by your immune system mistakenly attacking receptors in your brain, a condition called autoimmune encephalitis. This test looks for the antibodies behind that kind of attack, which can also occasionally be linked to an underlying tumor.

How should I prepare for this test?

How can I naturally support brain and nervous system health? Getting enough quality sleep, staying physically active, eating a diet rich in omega-3 fats and antioxidants, and managing stress all support healthy brain function day to day. That said, these habits are general wellness support and are not a treatment for autoimmune encephalitis, which needs prompt medical attention if antibodies are found.

What's included in this test?

This panel checks for several different antibodies that target specific receptors and proteins in the brain. Each antibody is associated with a different pattern of symptoms, so testing for several at once helps narrow down what might be causing neurological changes like seizures, memory loss, or personality shifts.

What happens after I get my results?

Your results will show up in your account with an explanation of what a normal versus a positive antibody result looks like. Because this is a specialized neurological test, a positive result calls for prompt follow-up care rather than a simple lifestyle change, and if you have severe or worsening symptoms like seizures or confusion, seek medical care right away. You can download a standard lab report from your account at any time, and if you're retested later you'll be able to track changes over time using the trends feature.

When will I get my results?

Results for this test are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification once they're posted to your account so you can log in and review them right away.

Who should consider this test?

This test is a good fit for anyone with new, unexplained neurological or psychiatric symptoms such as seizures, sudden confusion, memory loss, or psychosis, especially if these symptoms developed over days to weeks rather than years. It's also relevant if you have a known cancer diagnosis and develop new neurological symptoms, since some cancers can trigger this type of antibody response.

What symptoms indicate I may need this test?

Watch for sudden changes in behavior or personality, new-onset seizures, memory problems, confusion, hallucinations, or unusual movements. Rapid decline in mental function over days or weeks, rather than a slow gradual change, is a particularly important signal. If any of these symptoms are severe, seek medical care immediately rather than waiting for test results.

What does a positive antibody result mean?

A positive result means your immune system has made antibodies that target specific brain receptors, which can interfere with normal brain signaling and cause the symptoms you've been having. It doesn't tell you the exact cause on its own, but it's an important piece of the puzzle that helps explain neurological or psychiatric symptoms that don't fit a typical pattern. This finding should prompt fast follow-up since treatment often works best when started early.

What causes these antibodies to develop?

Sometimes these antibodies develop because a tumor elsewhere in the body triggers an abnormal immune response that cross-reacts with brain tissue, known as a paraneoplastic reaction. Other times they appear on their own without any detectable tumor, called idiopathic autoimmune encephalitis. Viral infections have also been linked to triggering this type of antibody response in some cases.

What should I do if my results are abnormal?

If your antibody test comes back positive, don't wait to act. Follow up quickly to figure out next steps, since these conditions can progress and often respond best to prompt intervention. If you experience worsening symptoms like seizures, severe confusion, or trouble breathing in the meantime, seek emergency medical care.
