Crayfish, Freshwater

This test measures the amount of specific antibodies in your blood that react to proteins found in freshwater crayfish. It helps show whether your immune system is sensitized to this crustacean, which is important if you have experienced itching, swelling, or breathing issues after eating shellfish. This analysis helps distinguish a specific allergy to crayfish from reactions to other foods or environmental factors. However, the test cannot predict exactly how severe a future allergic reaction will be based on the antibody levels alone.
