For measuring the level of IgE antibodies present in the blood, Allergy Banana test is performed. Apart from it, the allergic banana test can also be performed on the skin. Itching of mouth, hives (urticaria), swelling (angioedema) and wheezing are some of the common allergic reaction after eating banana. If you are having an allergy to banana then your body may react to avocado, kiwi and chestnut fruits also. It is better to avoid fruit salads, fruit drinks that contain banana as an ingredient. Be careful while choosing a shampoo or body lotion also, as they also contain banana as an ingredient.
