Skin tests are performed by injecting a small amount of an allergen just under the skin. This test is no more painful than a needle stick, and will usually give an indication within twenty minutes of application. Skin testing is the most accurate type of diagnosis for most allergies. Blood testing requires sending a small sample of blood to an outside laboratory, and generally less accurate than skin testing. It may help to uncover food allergies, and is sometimes considered a useful diagnostic tool.
Food allergies can be difficult to pinpoint.
If an allergy is caused by a pet, down pillow, wool sweater, or certain food, removal of the allergen will eliminate the symptoms. We are not saying you have to get rid of your pet, but sometimes that will help your allergic response. If you have bad allergies, this is something to discuss with your family and health care provider if you test positive for allergies to cats and or dogs or feathers from your bird. Millions of different antibodies circulate in your bloodstream and are present throughout your body to help fend off any unwanted substances. This results in swelling, redness, and inflammation and leads to unpleasant symptoms such as an itchy, stuffy, or runny nose.
