Mackerel

This test measures the level of specific antibodies in your blood that react to proteins found in mackerel. It helps show whether your immune system recognizes this fish as a threat, which is useful for investigating symptoms like hives, swelling, or breathing trouble after eating seafood. While this helps identify if mackerel is a potential trigger for your symptoms, it cannot predict how severe a future allergic reaction might be.
