Allergy Testing

Does allergy testing use needles?

Yes and no: Allergy testing is done with small plastic devices that scratch the skin. A positive test will look and feel like a mosquito bite minutes after the test is placed. After the test area is washed off, cream is applied and the skin reactions are typically gone within 1 hour. Occasionally testing with small needles is done for adults and in special circumstances such as penicillin and bee sting testing.


Do I have to have allergy skin testing?

No, the decision on testing will be made after consulting with Dr. Zacharisen to determine whether it is necessary.


Where are allergy tests placed?

Testing is done on the middle of the back, but on occasion will take place on the forearms of adults. It will not be placed on skin that is sunburned or where there is a rash.


Is there an alternative to skin testing for allergies?

Yes, a blood test can be done. It may take a week to have the results and may be less accurate in identifying some allergies.
