What's this test for?

This test is ideal if you're experiencing sudden confusion, memory problems, unusual mood changes, seizures, or hallucinations that came on quickly and can't be explained by another cause. It looks for specific antibodies in your blood that are linked to a rare condition called limbic encephalitis, which can sometimes be tied to an underlying tumor. It's also useful if you're already being treated for this condition and want to see how well treatment is working.

What's included in this test?

This panel checks for several different antibodies that the body sometimes makes by mistake, which then attack the nervous system and cause brain inflammation. Each antibody type is linked to slightly different symptoms and, in some cases, different types of tumors, so testing for several at once gives a fuller picture of what might be going on. Grouping them together also helps because these conditions are rare and can look similar to other neurological or psychiatric problems.

What happens after I get my results?

Your results will show up in your secure online account, with each antibody result explained alongside what counts as a normal versus a positive finding. If any antibodies come back positive, the report will walk you through what that means and suggest getting further evaluation quickly, since these conditions can progress fast. You can download a standard lab report for your records at any time, and if you retest later to track treatment progress, the trends feature lets you compare results side by side over time.

Who should consider this test?
This test is worth considering if you've had a sudden, unexplained change in thinking, memory, mood, or behavior along with seizures or hallucinations, especially if brain imaging has shown changes in the temporal lobes. It's also relevant if you have a history of cancer and develop new neurological symptoms, since these antibodies can sometimes appear before a tumor is even found. People already diagnosed with a paraneoplastic neurological condition may also use this test to monitor how they're responding to treatment over time.
What symptoms indicate I may need this test?
Watch for a fast onset of confusion or memory loss, personality or mood changes, anxiety or depression that feels different from usual, seizures, or hallucinations. These symptoms often develop over days to weeks rather than gradually, which is a key clue that something acute is happening in the brain. If you notice several of these symptoms together, especially alongside a history of cancer, it's a good reason to get checked.
When will I get my results?
Results are typically ready within about 7 days of your sample being processed at the lab. Because this is a specialized antibody panel, it takes a bit longer than routine bloodwork, so plan accordingly. You'll get a notification as soon as your results are posted to your online account.
What does a positive antibody result mean?
A positive result means your body has made specific antibodies that are known to attack the brain and nervous system, which can explain symptoms like confusion, seizures, or hallucinations. Because certain antibodies are also linked to specific tumor types, a positive result is often a signal to pursue prompt follow-up imaging or cancer screening. This isn't something to manage on your own — if your result is positive, especially with worsening symptoms, seek medical care right away.
What does a negative result mean?
A negative result means none of the antibodies in this panel were detected, which makes limbic encephalitis from these specific causes less likely. However, if your symptoms are still present and severe, negative results don't rule out every possible cause, so continuing to track symptoms and seeking further evaluation is still important. Keep a record of your symptoms and consider retesting if your doctor previously suspected a specific antibody that can take time to become detectable.
How often should I retest?
If you're being monitored for treatment response, retesting every few months is common, since antibody levels can drop as symptoms improve with treatment. If your initial result was negative but symptoms persist or worsen, your care plan may call for retesting sooner. Use the trends feature in your account to track how your levels change over time.
What should I do if my results are abnormal?
If any antibodies test positive, don't wait — these conditions can move quickly, so seek prompt medical evaluation, especially if you have worsening confusion, seizures, or new neurological symptoms. Bring your downloadable lab report with you so it can be reviewed alongside imaging or other tests. In the meantime, keep a log of your symptoms including timing and severity, since this information helps guide next steps.

What this means

A negative result means this antibody, which is linked to a type of brain inflammation called anti-NMDA receptor encephalitis, was not detected in your blood. This makes that specific cause of your symptoms less likely, though other antibodies in this panel or other conditions could still be responsible for how you're feeling. Continue tracking your symptoms closely.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
