Allergy Skin Test

An allergy skin test is used by doctors to determine whether patients have allergies and if so, which substances they are allergic to. The allergies most commonly tested for are hay fever, asthma, dermatitis, food allergy, penicillin allergy, and bee sting allergy. The patient is exposed to a small dose of different allergens to determine whether they have any reaction to them and if the patient begins to exhibit negative symptoms after the allergen has been placed on their skin, it’s a good indicator that the patient might be allergic to that specific substance. Negative symptoms might include rash, sneezing, and coughing. There are some cases in which an allergy skin test shouldn’t be conducted. If the patient is taking certain medications or has a serious skin disease, it can interfere with the results by deactivating the test or making it hard to see results on the skin. If the patient is too sensitive to allergens, performing an allergy skin test can be dangerous.

The allergy skin test is conducted by pricking, scratching, injecting or applying a patch with the allergen to the skin. A prick or scratch is used to test for an immediate allergic reaction. A patch is worn around by the patient to test for a delayed allergic reaction. Along with the allergen, the patient will also be exposed to histamine and saline to make sure the results are interpreted accurately. Histamine is a substance inside our bodies that triggers inflammation in response to pathogens. If the patient’s skin doesn’t react, it might be difficult to get results from the allergy skin test. Saline is a substance that’s supposed to be harmless, so if the patient reacts to it, they might have overly sensitive skin. In this case, an injection will be used instead. If the patient does have an allergy, a red bump will appear on the skin and its size will be measured. In this case, the patient can speak with a doctor to discuss possible treatments.

The simplest way for the patient to prevent allergies is to avoid that substance. For example, if the patient turns out to be allergic to peanuts, then they can stop eating Snickers bars and peanut butter. However, if living life while trying to avoid the allergen is fairly difficult, then the patient can seek out treatment to help. For example, it’s hard to control whether pollen will fly your way or whether a bee will fly out of nowhere and sting you, so you should protect yourself as best as you can.
