Allergy Prevention
Posted by Bronchitis - 29/08/10 at 12:08 pmDid you ever wonder what might be involved in having an allergy test? Don’t worry, it’s nothing to be concerned about. Testing for allergies is quite easy really. A quick test measures exactly what reaction a person may have to a certain set of allergens such as pollen, dust, pet dander, mold, various types of medication and foods such as peanuts.
Actually, there are two types of allergy tests that are widely used. You can have a skin test, which involves a slight prick on your skin, or RAST, which is otherwise known as radioallergosorbent testing, where blood samples are checked.
The assessments commonly take place in a doctor’s lab or surgery. If you receive the test from an “allergist,” well, think again! - he or she might not be qualified enough to do it! There are some allergy skin testing practioners out there who are not properly qualified.
The skin test is probably the most popular type of allergy testing. It’s been in use now for more than a 100 years and it continues to be the preferred test of choice. At the beginning of the test, you should expect to have a slight cut, either through a prick, scratch, or using a puncture method.
After that, a tiny drop of liquid containing the allergen to be tested is placed on top of the cut. Contrary to what you may be thinking, this doesn’t really hurt at all. The cut is far too microscopic to be the cause of any pain. The needle used barely scratches the surface of the skin and it is rare that you will have any evident bleeding.
Soon after the solution containing the allergen is put over the cut, the skin is expected to react within 10-15 minutes if there is going to be a response. A positive skin test result is indicated by an itchy red or pink bump that starts to form that looks a little like the reaction you would get from a bug bite.
In cases where you get a positive allergy test, it shows that your body has antibodies to the solution being tested. What that means is that you are probably going to experience some allergy symptoms in relation to that specific substance.
This positive result doesn’t necessarily mean that you’re allergic. After you see the red bump formation, the test will then be followed up by comparing to two other tests with the same allergen as the first, alongside a negative control, such as saltwater and a positive control, a histamine. You will then need to wait to see what, if any, reactions to these two are. These two additional tests are put there to ensure you aren’t simply reacting to the pricking of the needle itself.
If your test results turn out to be negative, even though your history of allergic reactions predict that you should be allergic, you will receive another test. This test is named intradermal skin testing.
This means you need to work with a weaker allergen solution under the utmost layer of the skin. This is done by using a small needle, which again, doesn’t hurt at all, so you needn’t worry. This can be done for all kinds of allergies including an allergy test for joint pain in cases where you are suffering from an allergy in this part of the body.
The two skin tests show slight allergic reaction that are so helpful in determining the reactions in common allergies and symptoms. It provides you with some idea of the look and feel of the allergic reaction so you know how to identify whether you’re having an allergic reaction or if it’s simply an insect bite of some kind. This will enable you to be more in control of staying away from environments that otherwise cause an allergic reaction such as to stop eating peanuts, stop being near cats, dogs, staying away from high pollen areas, etc.
Knowing what allergy testing involves will help you prepare more easily for and be less scared of what it is all about. Many people avoid testing because they are afraid about what it involves but the relief they can get from allergy symptoms once they’re informed can really make up for that. This indeed is a sure way to successful allergies relief.
