# Lettuce

> This test measures the level of IgE antibodies in your blood that specifically react to proteins found in lettuce. It helps show if your immune system is identifying lettuce as a threat, which can explain symptoms like mouth itching, hives, or stomach upset after eating it. This information helps doctors determine if lettuce is the cause of your symptoms rather than other foods or ingredients. However, this test cannot predict how severe a future reaction might be or diagnose food intolerances that do not involve an immune response.
