FAQ
Frequently asked questions
What do the results mean?

Do I need to avoid oysters before the test?

Can this test tell me if I outgrew an allergy?
This test can be used to monitor changes in antibody levels over time, but it is not definitive for determining if an allergy has been outgrown. Your clinician may recommend additional testing or an oral food challenge.
Are there other shellfish I might be allergic to?
Yes, allergies to other shellfish such as shrimp, crab, and lobster are common. If you are allergic to oysters, you may also react to other shellfish, so discuss this with your clinician.
