What Types of Allergy Tests Are Available for Pets?

If your furry friend seems to be sneezing more than usual or scratching incessantly, consider allergy testing. Just like humans, pets can suffer from allergies, and pinpointing the cause can be tricky without proper tests. So, what types of allergy tests are available for pets? 

What Are Pet Allergies

Before we get into the specifics of the tests, it’s important to grasp what pet allergies entail. Pets can react to numerous allergens just like humans, including pollen, dust, certain foods, and even fleas. Symptoms can range from mild itching to severe respiratory distress.

Signs Your Pet Might Have Allergies

  • Excessive scratching or biting

  • Frequent ear infections

  • Red, inflamed skin

  • Continuous sneezing

  • Gastrointestinal issues like vomiting and diarrhea

Types of Allergy Tests for Pets

The good news is that several pet allergy testing methods are available. Let’s explore the most common ones.

1. Intradermal Skin Testing

Intradermal skin testing is often considered the gold standard when it comes to diagnosing allergies in pets. This test involves the following steps:

  • A small area of your pet’s skin is shaved.

  • Different allergens are injected just under the skin.

  • The vet observes the reaction over 24 hours.

The size of the reaction will help determine what your pet is allergic to.

2. Blood Testing

Blood tests can be a less invasive alternative and are particularly useful if your pet cannot undergo skin testing. There are two main types:

  • RAST (Radioallergosorbent Test)

  • ELISA (Enzyme-Linked Immunosorbent Assay)

These tests measure the amount of allergen-specific antibodies in your pet’s blood.

3. Patch Testing

Patch testing is another method used less frequently. Here’s how it works:

  • Allergens are applied to patches.

  • The patches are then placed on your pet’s shaved skin.

  • Reactions are monitored over 48 hours.

This helps determine skin allergies caused by direct contact with allergens.

4. Food Elimination Trials

If your pet is suspected to have food allergies, a food elimination trial may be recommended. This involves:

  • Feeding your pet a special, hypoallergenic diet for 8-12 weeks.

  • Gradually reintroducing suspect foods one by one.

  • Monitoring for any allergic reactions.

This method can be time-consuming but is highly effective.

How Do These Tests Work?

Each type of allergy test for pets has its procedure and timeline. Here’s a quick breakdown:

  • Intradermal Skin Testing: Immediate results within 24 hours.

  • Blood Testing: Results usually within a week.

  • Patch Testing: Results take about 48 hours.

  • Food Elimination Trials: 8-12 weeks.

Pros and Cons of Each Test

Every method has its benefits and drawbacks. Here’s an overview:

Intradermal Skin Testing

  • Pros: Highly accurate, quick results.

  • Cons: Invasive, may require sedation.

Blood Testing

  • Pros: Less invasive, suitable for pets unable to undergo skin tests.

  • Cons: Slightly less accurate, longer wait for results.

Patch Testing

What to Expect During Allergy Testing

Knowing what to expect can set your mind at ease. Here’s what typically happens during each test:

Intradermal Skin Testing

Consulting Your Vet

It’s always best to consult with your vet to determine the most suitable test for your pet. They will guide you through the steps and help interpret the results. This is crucial, especially if you need to visit an emergency vet due to severe reactions.

Interpreting the Results

Once testing is complete, your vet will help you make sense of the results. This usually involves:

  • Identifying specific allergens.

  • Creating a treatment plan, which may include medication, lifestyle changes, or special diets.

  • Follow-ups to track progress and adjust the plan as needed.
