Common Methods of Allergy Testing
Below are some of the common methods of allergy testing and double up as treatment for it. As allergies is the natural response of our immune system trying to defend our body when it feels it is in danger; usually allergies occur when the body does not recognize a substance that is induced in the form through air, orally or directly applied on the skin. The Skin Prick Or Scratch Allergy Testing This is one of the most common allergy testing used and it is conducted by inducing a small amount of the substance suspected to cause the allergy into the skin in order to make contact and provoke the allergy. This test usually takes about half an hour to maximum an hour as the body reacts almost instantly if there are any allergic reactions to the substance used. This is a fast and sure way to find out if you are allergic to something that you suspect you are but unsure. You can conduct this test with several other suspected substances concurrently in order to find the right culprit and a possible treatment as well. Intradermal Allergy Testing This allergy testing is very similar to the skin prick o scratch testing with the only difference that the suspected allergens are injected into the skin so as to provoke the reaction desired. Several tests can be conducted at the same time as it takes approximately half an hour for any reactions to occur. Blood Test Blood tests or RAST (radioallergosorbent test) is yet another sure way to find out an allergic reaction; this test measures the level of antibodies in the body or more precisely of a specific type of antibodies, which are known as IgE that are only present when an allergic reaction occurs. Helpful Tip Allergy reactions can be very tricky sometimes and it can take several allergy testing procedures to determine the cause of your allergies because it can be anywhere from food to a new lotion you are applying. You also need to remember that allergies can be formed even later in life for some food items that you were not allergic to before, or any other cause for that matter such as, flowers, perfume animal dander or dust. In fact as we aged, our immune system grows weaker and we are more prone to develop allergies to things that did not bother us before. Therefore, it will be good to go for allergy testing at times to check your sensitivity level of that allergy as prevention is stil much better than cure.
