An allergy skin test is utilized by doctors to determine whether their patients have allergies and if they do have an allergy, then which substance or substances they are allergic to.
The allergies that are most frequently tested for are hay fever, dermatitis, asthma, a penicillin allergy, a food allergy, and a bee sting allergy. During the test the patient is exposed to a small dose of a variety of different allergens to determine whether they have any reaction to them. If the patient begins to exhibit some negative symptoms following the allergen being placed on their skin, then that’s a good indicator that the patient might be allergic to that particular substance.
Negative symptoms typically might include a skin rash such as hives, or sneezing, or coughing.
There are some instances in which an allergy skin test should not be conducted. For example, if the patient is taking certain medications or suffers from a serious skin disease, these can interfere with the results by deactivating the test or making it difficult to see results on the patient’s skin. In extreme cases, if the patient is overly sensitive to allergens, then performing an allergy skin test could be dangerous.
An allergy skin test is performed by pricking, or scratching, or by injecting or applying a patch with the allergen on it onto the skin. A prick or scratch procedure is used to test for an immediate allergic reaction, whereas a patch is worn around by the patient to test for a possible delayed allergic reaction.
Along with the specific allergen, the patient is also exposed to both histamine and saline to make sure that the results can be interpreted accurately. The histamine is a substance that is inside our bodies which triggers inflammation in response to pathogens. If the patient’s skin doesn’t react, it could be difficult to get true results from the allergy skin test. The other one, Saline, is a substance that s regarded as harmless, so if the patient shows a reaction to it, they
might have overly sensitive skin.
In this scenario, an injection will then be used instead. If the patient does in fact have an allergy, then a red bump will appear on the skin and its size will be measured. Then the patient can speak with a doctor to discuss a possible treatment.
The simplest way for the patient to prevent allergic reactions in the future, and having to find treatments to relieve the symptoms, 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. Or if a patient breaks out in hives every time they eat strawberries, then they should simply not eat strawberries, no matter how much they love them - that’s way less of a hardship than having to start searching for ways to treat hives.
However, other scenarios are not so easy to deal with - 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 pretty much impossible to control whether pollen will fly your way, or whether a bee will fly up to you and sting you, so you should protect yourself as best as you can.
