Frequently asked questions

What does a positive test result mean?
A positive result indicates your body has detected antibodies to the Echinococcus parasite, which may mean you have had or currently have an infection. This does not necessarily mean you are actively sick right now, but it confirms past exposure or infection. Your healthcare provider will discuss the next steps based on your symptoms and medical history.
Can I have this test if I’ve never been exposed to animals?
Yes, this test can be done regardless of exposure history. It’s important for anyone with symptoms or risk factors for Echinococcus infection. If you’ve never been exposed, a positive result would still be significant and warrant further evaluation.
How long does it take to get the results?
Results are typically available within a few days to a couple of weeks, depending on the lab and your healthcare provider’s workflow. Your provider will contact you once the results are ready.
