A blood test called an Allercept test is performed to determine which allergens are causing an allergic reaction in canines and felines. If you want to know if your pet has allergies, discuss Allercept allergy testing for dogs and cats with your vet. An Allercept test calculates the blood’s concentration of IgE antibodies, which are generated in response to exposure to particular allergens. The test can pinpoint the allergens causing an animal’s symptoms, enabling vets to create a successful treatment strategy. Since other diagnostic procedures, such as skin tests, are unreliable or impractical given the animal’s condition, allercept testing is frequently used.
