What's this test for?

This test is ideal if you're experiencing unusual numbness, tingling, or loss of coordination in your arms and legs that came on suddenly. It's often used when someone has had a recent infection followed by nerve-related symptoms, such as trouble sensing touch, balance issues, or muscle weakness. This test helps identify a specific antibody linked to a rare nerve condition called acute sensory ataxia neuropathy, a variant of Guillain-Barre syndrome.

What's included in this test?

This test measures a single, highly specific antibody that targets a component of nerve cell coverings. Because this antibody is closely tied to a particular nerve disorder, checking for it helps narrow down the cause of sudden sensory and coordination symptoms rather than screening broadly.

What happens after I get my results?

Your results will show up in your online account, with the normal reference range explained next to your value so you know exactly what it means. If your result comes back positive, it's important to seek medical care promptly since this antibody is linked to a nerve condition that can progress quickly. 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 compare results side by side.

How can I naturally support nerve health?

While this antibody itself isn't something you can change through lifestyle, supporting your overall nerve health can help your body recover and function well. Eating foods rich in B vitamins (like leafy greens, eggs, and whole grains), staying physically active within your comfort level, and managing stress can all support nerve function. Getting enough sleep and avoiding alcohol and smoking also help your nervous system stay healthy.

When will I get my results?

Results for this test are typically ready within about 7 days after your sample is collected at the lab. You'll receive a notification once your results are posted to your online account, where you can view your value alongside the normal range. If your situation feels urgent based on your symptoms, don't wait for results — seek medical care right away.

Who should consider this test?

This test is a good fit for people who have recently developed sudden numbness, tingling, or balance problems, especially after a cold, flu, or stomach bug. It's also useful for anyone whose recent lab work or symptoms have raised concern about a nerve-related autoimmune condition. If you've had unexplained sensory changes that a routine checkup hasn't clarified, this specific test can provide helpful information.

What symptoms indicate I may need this test?

Common symptoms include a sudden loss of sensation or numbness in your hands and feet, poor balance or coordination (feeling unsteady when walking), and tingling or pins-and-needles feelings that spread over days. Some people also notice muscle weakness or difficulty with fine motor tasks like buttoning a shirt. These symptoms sometimes follow a recent infection, which is a common trigger for this type of nerve condition.

What does a positive result mean?

A positive result means this specific antibody was detected in your blood, which is associated with a rare nerve condition affecting sensation and coordination. This finding, combined with your symptoms, can help explain what's causing sudden numbness or balance issues. Because this condition can worsen quickly, a positive result should prompt you to seek medical care right away rather than waiting.

What causes this antibody to appear?

This antibody often appears after the immune system, in the process of fighting off an infection, mistakenly starts attacking a component of your own nerve cells. Common triggers include recent respiratory or gastrointestinal infections. This misdirected immune response is what leads to the nerve symptoms associated with this condition.

What should I do if my results are abnormal?

If your result is positive, treat it as a signal to seek medical care as soon as possible, since this condition can progress and affect breathing or movement if untreated. In the meantime, avoid overexertion and pay close attention to any new or worsening symptoms like difficulty breathing or swallowing. Keep a record of when your symptoms started and how they've changed, as this information is helpful for urgent care providers.
