Numerous things can cause a runny nose or rashes to suddenly appear on the skin but determining if these conditions are the result of an allergic reaction requires a professional diagnosis. Amongst the most common and successful methods used to test for allergies are skin tests. Allergy testing procedures inject or scratch a small quantity of the potential allergen, such as pollen extract, solution containing animal dander proteins and others under the skin.

It is very seldom that an allergy becomes a risk to life. Admittedly, a number of folks are so sensitive to wasp venom they can die from a solitary sting, if not treated right away. Similarly, asthma can have serious effects as well, but for the majority, allergies are simply a pain in the neck. Not only do they make it difficult to focus, they also make us itch, cause runny noses and watery eyes, encourage wheezing and a catalog of other frustrating symptoms.
