They have several different allergens pulled up into small TB needles and just bearly stick the very small needle under the skin and inject a very small amount of the allergen. You than sit tight for about 15 min without scratching. You will start to notice welts developing where the allergens are producing a reaction. Those will be the things you are allergic to. They will be able to tell you what is in every vile and how large of a reaction you had to it. They will then wipe the area down with a substance that keeps them from itching any longer. They can also perform a blood test but it is not a definitive as the allergen test.

Ah, my favorite subject! First, there are 2 types of allergy testing. Type I is for foods, plants, animals, pollens, etc. Type 4, what I used to do in a doctor's office, is for chemicals that you might come in contact with. Things found in perfumes, lotions, hair dyes, clothes soap, etc. Type 4 testing is done without needles and is patches that you wear on your back for 48 hours. Each patch is numbered and when the patches are taken off, the nurse or doctor matches any possible reaction, like reddness,bumps or swelling, with the name that matches the number. They should then give you an info sheet telling you what it was that you are allergic to and the source of the exposure. Any example would be if you were allergic to formaldehyde. Alot of people automatically think of dead bodies or preserved rats and cats for anatomy classes. But, there is formaldehyde in ALOT of stuff that we use daily. There is formaldehyde in some pancake syrups and make up, even Johnson & Johnson Baby Shampoo. So, it is pretty extensive and should help you find your source of an allergy. Good Luck!

I had that done a month before my tonsils were taken out and sinus surgery was done and it was HORRIBLE. Its so annoying the doctor pricked me with 6 like..needles in one arm and they inject a little bit of something into you to see if a rash comes up. Then they give you like 16 shots in the other arm. It sucked and it was so annoying it hurt a lot and I ended up having no allergies!

there are several ways to perform an allergy test. when i had mine, they gave me tiny little shots of things i could be allergic to on my back in a small area. then about 5 minutes later they check to see if i had had an allergic reaction to them by looking to see if the skin was raised where they put the sample of stuff... where ever the skin was raised was what i was allergic to...

they did it to me ... they put a special liquid that contains certain things that you can be allergic to (like pollen or cats or dogs) on your skin ... then they stick a tiny pin (which doesnt hurt) into the skin so the liquid goes in ... then after a few minutes you might that the skin is swollen ... and depending on what the liquid is.. it basically means that your allergic to it. if its not swollen .. your not allergic to it! =)

They use test areas on your back with substances that most humans are exposed to. If one or more than one area becomes red and irritated, then it is determined that you are allergic to that substance.

they give you shots or pricks and see what you react to but it cant hurt you it just swells around the injection.
