Video Link

Background/Purpose

The symptoms of dog allergies are usually like those of any other nasal allergy. They include:

coughing and wheezing
red, itchy eyes
runny, itchy, stuffy nose
sneezing
Some people with dog allergies also have skin reactions. For instance, their skin might break out where a dog licks them. Others with more severe allergies might develop hives on their face or chest. People with asthma as well as pet allergies can have especially serious symptoms.

The symptoms are often the result of dog dander which is the flakes of dead skin.

Procedure

The test area is cleaned and labeled using an appropriate skin marker. When multiple tests are being performed there should be a minimum of of 3cm between them. The skin is pricked lightly and quickly vertically through the sample allergen . A new micro lancet should be used for each substance being tested. The excess sample allergen should be removed immediately with an absorbent paper towel.
The wheals should be read after 15-20 minutes. For a positive reaction, the wheal should be >= 3mm in diameter. A valid result also requires a positive histamine reaction >=3mm and a negative saline control reaction of < 3mm.
Performed: Bilaterally
