# Grapefruit

> This test measures the level of specific antibodies in your blood that react to proteins found in grapefruit. It helps determine if your immune system treats grapefruit as harmful, which can explain symptoms like mouth itching, hives, or stomach upset after eating citrus. This testing helps distinguish a specific allergy to grapefruit from other food sensitivities or reactions to different fruits. However, a positive result does not predict the severity of a future allergic reaction on its own.
