# Herring

> This test measures the amount of specific antibodies in your blood that react to proteins found in herring. It helps determine if your immune system views this fish as a harmful invader, which is useful if you experience symptoms like hives, swelling, or stomach upset after eating seafood. This analysis helps distinguish a specific allergy to herring from other food sensitivities. However, a positive result cannot predict the severity of a future allergic reaction or diagnose food intolerance by itself.
