FAQ
Frequently asked questions
What are the symptoms of a fish allergy?
Symptoms can range from mild to severe and may include hives, itching, swelling, digestive issues, or difficulty breathing. Reactions can occur rapidly after eating fish.
Can this test be done if I am currently taking allergy medication?
It is best to check with the laboratory or your healthcare provider. Some medications may affect test results, and you might be advised to temporarily stop certain medications before the test.
How is this test different from a skin prick test?
This is a blood test that measures specific IgE antibodies in your blood. A skin prick test involves placing small amounts of allergens on the skin and observing for a reaction.
What does it mean if my test result is positive?
A positive result suggests that your immune system may have reacted to that specific fish. However, a positive result does not always mean you will have a reaction, and it should be discussed with your doctor.
