Skin Prick Test
SPTs only here and there produce "bogus negatives" (incorrect outcomes showing that you are not adversely affected by a food, despite the fact that you truly are). Negative outcomes quite often imply that you are not sensitive to a food. Positive tests, be that as it may, are not generally precise. Around 50-60 percent of all SPTs yield "bogus positive" results, implying that the test shows positive despite the fact that you are not so much adversely affected by the food being tried. These outcomes happen for two reasons: At the point when you eat, your stomach related framework slowly separates food proteins into little pieces. Accordingly, the allergenic proteins might be little to such an extent that the IgE antibodies can't recognize them, so the food is really alright for you to eat. However, SPTs and blood tests can't impersonate the stomach related procedure. Since food proteins are greater when they associate with your skin or blood, it is simpler for the IgE antibodies to "see" the allergens and assault them. This is the reason your tests may show that you are more delicate to a speculate food than you truly are. Individuals from a food "family" frequently share comparative proteins. For instance, on the off chance that you are susceptible to peanuts, your tests may demonstrate a positive reaction to different individuals from the vegetable family, for example, green beans, regardless of whether eating green beans has never been an issue for you. This is known as cross-reactivity. The test is sure in light of the fact that it perceives a comparative protein in peanuts and green beans. In any case, the test hasn't recognized the genuine guilty party—another, distinctive protein that is discovered uniquely in peanuts.
