 - Nelco Allergy Test

Just like us, allergies can affect our pets all year round or seasonal. Not treating allergies in your pet can lead to skin issues, ear infections, scratch wounds and more. If your pet is experiencing major to severe allergy symptoms, they may be eligible for the Nelco-Vet allergy test! This widespread blood test measures antibodies in the bloodstream specific to environmental allergens (grasses, trees, dust, molds, etc.) and foods (chicken, beef, fish, at.). For this test, a small blood sample is sent to Nelco-Vet.

 - Pathology/Cytology

Typically done with lumps, a sample is sent to a certified pathologist who looks for malignant vs cancerous cells.

 - Horse Coggins (EIA)

Nationwide blood testing for equine infectious anemia. This test is required for crossing state lines/travel, many trainers, horse shows, rodeos, and most reputable sales.
