Unfortunately there are so many people in the world that suffer from some sort of allergy. This can vary from minor problems to potentially life-threatening allergies. Even if you only have minor problems you'll still want to get to the bottom of it all and the way you can do this is to get an allergy test.
Skin Tests
A skin test is one of the most popular means of testing for an allergy. Basically they place a small amount of the possible allergen under the skin. This allergen might be pollen, dander , food or something else.
So that the test results can be depended upon, you need to stop taking medications such as Allegra, Benadryl and Claritin as it can take quite a while for these meds to fully get out of your system. Unfortunately if you keep taking them they can potentially interfere with the accuracy of the test therefore making it difficult to find out what you are allergic to.
There are different tests that you might have done whilst visiting the doctor. These are:-
A percutaneous test punctures or pricks your skin. Small amounts of the allergens are put into the skin near the surface. Pollen, dander, dust mite waste and such like are typically tested with this method.
An intracutaneous test carried out by injecting the allergen into the skin, normally deeper than a scratch test. This is better test when testing for bee and wasp sting allergic reactions along with other things such as penicillin.
An epicutaneous or patch test is used for detecting skin allergies, for instance sensitivity to latex or perfume. Loads of people can have nasty reactions to hair dyes or preservatives and this is referred to as dermatitis. A patch is placed on the skin for quite a while and then the doctor looks for certain reactions.
When adults are tested for allergies the tests are normally carried out on the forearm. However for children it's normally on the upper back. If you are worried that the tests will be painful, don't worry because they aren't. At worst they are mildly uncomfortable if an allergy is found. So this means you can expect some itching, redness, swelling and such like if you are allergic to any of the substances used.
Blood Tests
In some cases, skin tests aren't suitable for certain people. It might be that they are especially sensitive or have some sort of condition that makes it unsafe. A blood test is therefore the option available to them. Unfortunately it's not as effective as skin tests and are more expensive to carry out.
A small quantity of blood will be taken so that the percentage of IgE (immunoglobulin E) can be looked at. It can give an indication of who might be allergic but is only accurate in about a third of cases. Blood tests are also used if the doctor is considering allergy immunotherapy or allergy shots for the patient.
Lots of people can have merely mild allergic reactions to substances but it still makes their lives uncomfortable. Therefore knowing what the problem is and how to deal with it can be of great help to them. Make sure you always get professional advice before getting any kind of treatment.
