Products - Protein Microarrays - AllerSpot™ Companion Animal Allergy Testing Service using Allergen Microarrays to Measure IgE Antibodies

62 Allergens, 1 Test, >90% Coverage

AllerSpot™ 62 Item IgE Screening Test is provided through professional Veterinarians only

The screening criteria for the 62 allergens is based on rigorous scientific studies and environmental research on various factors affecting the prevalence rates of allergies. Based on this information, we have identified the most common allergens that are inhaled or ingested by companion animals. This test is available to licensed Veterinarians only.

Arrayit AllerSpot™ Companion Animal Allergy Testing Kit. Test kit components include a sample collection protocol, sample collection card, pet information form, and return address envelope. For Veterinarian Use Only.

Advanced Testing Capabilities: Fast, accurate results reveal which allergens could trigger allergic reactions, enabling Vets to help Pet Owners to:

1. Choose suitable pet food;

2. identify causes of allergies in the environment; and

3. select appropriate allergy treatments.

Convenient Sample Collection: Regardless of your pet's size and age, only 1–2 ml of whole blood (or more than 0.2 ml of serum/plasma) is needed for testing. Acquired by licensed Veterinarian only.

Fast Results: A comprehensive and informative report is delivered in just 5 business days.

Valuable Information: The report clearly identifies the risk of allergic reactions for individual allergens. Suggestions and other helpful information about popular pet food brands are also provided in the “Food Recommendation List” so that informed decisions are made when choosing what to feed pets, and avoid allergies. Always follow the advice of your Veterinarian who will understand the test results.

Advantages: Conventional testing methods use the intradermal skin test. However, this procedure must be overseen by experts, as it involves complex techniques, medical observation and is uncomfortable for the pet.  Intradermal skin tests pose the risk of anaphylactic shock. This is why our approach is the preferred method utilized today...blood testing using microarray technology for the allergen-specifically antibody Immunoglobulin E (IgE).

Arrayit uses our microarray platform to provide allergy testing service. Based on the geographical prevalence of allergens in in a localized environment, with our commercial partner EBS, we have developed biochips which detect the 62 most common allergens that affect dogs and cats. Utilizing protein purification and specialized Arrayit microarray manufacturing techniques, allergen proteins are “nano spotted” onto the glass slide in a microarray format which miniaturizes and multiplexes the test, reducing waste and improving the accuracy, efficiency and sensitivity of allergy testing.  We provide a fast turnaround time of processing the samples, and can provide a quantitative analysis, easy to read report for interpretation by Veterinarians and provides good information for pet owners. Only a small volume of serum is required for this one-step testing method - very convenient while saving both time and money!  Knowing the allergens that pose a risk for your dog or cat, provides peace of mind at the same times improves the overall health condition of your companion animal.

The risk of allergic reaction is scored from low to high on a scale from 0 to 6 (7 levels in total). A minimal response (0–500/0) indicates low risk. Any indicated response greater than a weak positive response is considered a clinically significant risk. Although the severity of allergic reactions may not be directly related to the intensity/level of the test response, a higher intensity/level usually indicates a greater risk for allergic reactions in the pet.
