How much serum do we need to send to Pet Preferred Diagnostics for testing?

We require 1 ml of serum. That includes some spare volume in case if we need to rerun the test.

When will the allergy test for horses be available?

The allergy test for the equine will be available within the next 1-2 months.

How accurate and consistent is an allergy test?

An allergy test detects the IgE antibodies produced by the immune system as soon as the immune system sees the target. Then antibodies developed to fight the allergen remain in the system for a while. After a certain period, pets can be exposed to new allergens (pollen, for example). This means that a new allergy test will detect some new antibodies on top of the antibodies that are already present. The third allergy test can also detect antibodies against mold, for example, if a pet was exposed to mold after a humid season. Thus, three different tests could yield three different results, but it does not mean that the results are wrong.

What makes Pet Preferred Diagnostics have the largest allergy panels for the lowest price?

When we opened our laboratory in early 2020, our goal was to change that and make allergy tests affordable and available for all pet owners. We made this possible by utilizing modern scientific findings and a new generation of equipment, specifically designed for pet allergy testing.
