Quick answer
This test looks for IgE antibodies directed at green bell pepper proteins in a blood sample. It is helpful when reactions such as mouth tingling, hives, or stomach upset appear after eating green peppers. A healthcare provider interprets the result together with the reaction history.
What this test measures
Green bell peppers are the unripe fruit of the Capsicum annuum plant and belong to the nightshade family. IgE-mediated reactions to peppers are uncommon but can occur, with symptoms that may include oral itching, skin welts, or digestive discomfort. The test measures specific antibodies that the immune system produces against pepper proteins.
Only a blood sample is needed, collected through a routine venous draw. The laboratory reports green bell pepper-specific IgE, usually with total IgE and a graded reactivity class. Because peppers share some proteins with tomato, paprika, and other nightshades, panels may include related markers to place a positive result in context.
People order this test after noticing repeatable symptoms tied to green peppers, or when a wider food allergy evaluation is underway. Spice and vegetable allergies can be difficult to pin down from diet alone, so the laboratory result adds one piece of evidence for a clinician to weigh.
