Skin Allergy Testing

Skin testing, or scratch testing, is used to test for pollen, animal, or mold allergies. It is as close to painless as possible.

Scratch testing is done with a little piece of white plastic like the one shown below.

Skin Allergy Testing 1

The plastic device is used to lightly scratch the top level of skin. This scratching does not bleed or leave a visible mark.

Skin Allergy Testing 2

If the test is positive, a small hive the size of a mosquito bite, like the one shown below, develops. This small mark will last at least an hour.
