What's this test for?

This test is ideal if you're experiencing balance problems, uncoordinated movements, dizziness, or unexplained difficulty walking, especially if you also have a history of Hodgkin's lymphoma or unexplained lymph node swelling. It looks for a specific antibody that can attack the part of the brain controlling coordination. This is a specialized test typically used when more common causes of these symptoms have already been ruled out.

What's included in this test?

This is a single, targeted antibody test rather than a broad panel, so it focuses on one specific marker linked to a rare autoimmune reaction. It's ordered specifically to identify a pattern of antibody activity connected to certain nervous system symptoms and their possible link to cancer. Because it's highly specialized, it's usually not used as a general screening test.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what a positive or negative result means. If your result is positive, the report will explain that further evaluation for an underlying cancer, particularly Hodgkin's lymphoma, is an important next step, and you should seek medical care promptly. 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 side by side.

Who should consider this test?
People who have new, unexplained problems with balance, coordination, or eye movements, especially alongside a current or past diagnosis of Hodgkin's lymphoma, may want to consider this test. It's also relevant for anyone whose care team is investigating a possible paraneoplastic cause for neurological symptoms. This is a specialized test, not a routine wellness check.
What symptoms indicate I may need this test?
Common symptoms linked to this condition include a wobbly or unsteady walk, clumsiness with hands, slurred speech, double vision, or dizziness that comes on over weeks rather than suddenly. These symptoms happen because the antibody can affect the cerebellum, the part of the brain that fine-tunes movement and balance. If these symptoms are severe, sudden, or rapidly getting worse, seek medical care right away.
What is DNER and why does it matter?
DNER is a protein found on specific brain cells called Purkinje cells, which help coordinate smooth, balanced movement. In some people, especially those with Hodgkin's lymphoma, the immune system mistakenly makes antibodies against DNER, and this attack can damage those brain cells, causing balance and coordination problems. Finding this antibody can be an important clue in figuring out the root cause of unexplained neurological symptoms.
What does a positive result mean?
A positive result means the specific antibody was detected in your blood, which is strongly associated with an autoimmune reaction affecting brain cells involved in coordination. This finding is also linked to Hodgkin's lymphoma in many cases, so it's an important signal to pursue further evaluation quickly. Simple next steps include following up with imaging or additional testing to check for an underlying cancer.
What does a negative result mean?
A negative result means this particular antibody was not found in your blood sample at the time of testing. This makes the specific antibody-related condition less likely, but it doesn't rule out other causes of balance or coordination symptoms. If your symptoms continue, further testing or monitoring may still be useful.
How often should I retest?
This is not a routine test, so retesting is typically only recommended if your symptoms change, worsen, or if it's being used to monitor response after treatment for an underlying condition. There's no standard yearly schedule for this test the way there is for general wellness panels. Use the trends feature in your account if you do retest, so you can easily compare results over time.
What should I do if my results are abnormal?
If your result comes back positive, the most important next step is prompt evaluation for an underlying cause, particularly Hodgkin's lymphoma, since this antibody is strongly linked to that condition. Keep a record of your symptoms, including when they started and how they've changed, since this information is helpful for further evaluation. Because this finding can be serious, don't wait to seek medical care if your symptoms are worsening.

What this means

A negative result means the PCA-Tr antibody was not detected in your blood sample. This makes an autoimmune reaction against Purkinje brain cells less likely to be the cause of your symptoms. If balance or coordination problems continue, further evaluation may still be worthwhile.

* 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.
