Frequently asked questions
What does a positive scallop allergy test mean?

Can I eat scallops if my test is negative?
A negative result may make a scallop allergy less likely, but it does not completely rule it out. Some people may still react even with a negative test, so discuss any dietary changes with your healthcare provider.
How long does it take to get results?
Results are typically available within a few business days after the sample reaches the laboratory. The exact turnaround time can vary depending on the lab and any additional testing needed.
Is this test safe?
