Getting tested for allergies can never necessarily be necessary, however it can provide peace of mind (especially if you are paying a lot of money for your allergy medications) and can even help to avoid a serious allergy emergency or even a serious case of anaphylactic shock. Even accidental exposure to some allergens can also cause allergy testing and even allergy symptoms. Allergy tests are not 100% accurate due to the fact that most allergens cannot be seen by the human eye. However, the results of allergy testing can be used as a guide to determining if you are allergic to a particular allergen.
The most commonly used allergy test is the skin test. This involves swabbing a small amount of your skin with a cotton ball or cotton swab and looking for any signs of allergic reactions such as itching, redness or swelling. Different types of allergens produce different types of skin allergy symptoms and therefore testing methods may vary. A physician can test you for allergies using more sophisticated testing methods such as an Rast's test and/or a skin biopsy.
Another common method of allergy testing is at-home testing. There are many different at home kits available, which include special pens and needles that are used to inject a small amount of allergen into your skin. These are very effective at determining if you are allergic to various types of foods and other substances. These tests are generally performed on those who rarely visit the doctor.
The most common allergy testing involves pricking your skin with either a needle or a small plastic hypodermic needle. The needle is inserted into a blood vessel and blood is drawn from the vessel via the needle. Most allergies respond very well to this type of treatment. However, some intolerances do not have much to do with the blood and often times blood tests alone are not able to determine if you really do have a certain allergy or not.
Other types of allergy tests include patch tests and oral immunotherapy. A patch test is done by having a small patch, usually no bigger than a matchbox, placed on the inside of your forearm. This test gives results within minutes after the substance has been rubbed onto your skin. Patches can usually be removed after ten minutes and results should be available the same day.
Oral immunotherapy involves a process where small amounts of a particular substance are given to you to immunize yourself against it. This process involves repeating the same procedure that was used to test for allergies, only in this case the substance being tested is your immune system. Sometimes test results are displayed immediately after the substance is given to you, and sometimes you may have to wait a day before you can see the results. You'll know the type of allergy tested on your urine test results. For more information, talk to your doctor or allergist.
Home Allergy Test kits are becoming more popular as people realize how inexpensive they are to purchase. They also don't take long to administer so you will never have to leave your home. Your doctor may recommend one of these allergy tests, or he may recommend one of his other allergy tests. If he does recommend one of these he will be able to provide you with information about the substances involved in each test as well as the possible results.
Many people believe that home health screening kits are just another way to self diagnose allergies. However, while allergy test kits and home health screening kits can help provide insight into your reactions, they cannot make your allergies clear. Only your doctor can do that. However, having a health condition diagnosed by your doctor can empower him to give you the best treatment possible.
