The most common dog allergy test for humans is a skin prick test. In other cases, you might have a blood test for allergies rather than a skin test. The best test for you will vary depending on the circumstances.
DIY Skin Prick Allergy to Dogs vs. Blood Allergy Test
When you have dog allergy testing done, is blood or skin testing better?
Skin testing is most common. A skin test is conducted by placing a small dog allergen extract on the skin. Following this, the skin will be pricked by a small probe, which lets the liquid seep underneath the surface. You will then receive monitoring for redness, swelling, and other reaction signs that signal an allergy. The results tend to be evident within about 20 minutes.
Allergy blood tests can test for a wider range of allergies. These tests detect the levels of antibodies specific to allergies in your blood. When the body comes into contact with allergens, the immune system creates antibodies in a reaction to it. These antibodies tell your body to release chemicals, which then cause the allergy symptoms.
An allergy blood test will typically screen for multiple allergies at once, including pet dander. Blood tests are ideal if you’re not sure where the allergy is coming from. If you strongly suspect a dog allergy, a skin prick test might be all that is necessary.
Key Differences Between Blood Tests and Skin Tests for Allergies
Skin test results are available much more quickly than blood tests. With skin tests, you’ll have your results within a half hour after the test is administered. Blood tests, on the other hand, require several days for processing.
Skin tests react with more sensitivity than blood tests. When a person has darker skin, a skin test might be hard to accurately interpret. In addition, a skin test might be affected by medications a person takes, but a blood test won’t be.
In rare cases, skin tests can cause a person to have a serious reaction. Blood tests don’t carry this risk.
Skin tests are less costly than a blood test, which is helpful if you don’t have insurance or if your insurance won’t cover the cost of testing.
When a Doctor Might Order a Blood Test Instead of a Skin Test
A doctor may order a blood test if testing young children or infants, since a blood test only requires one needle prick. Skin testing requires several more pricks. This also makes blood testing more ideal for people with a fear of needles or particularly sensitive skin.
Blood tests help avoid the potential for strong allergic reactions, so a doctor might recommend them for people with a history of anaphylactic shock.
A blood test also might be recommended if a person is using medication that has the potential to interfere with a skin test, like antihistamines or skin-related medications.
If a person already has an existing skin condition like eczema or psoriasis, a doctor might recommend a blood test to avoid the potential of aggravating the condition further.
How to Tell If Allergic to Dog
If you suspect you have a dog allergy, you should take an allergy test to see if you’re allergic to dogs. How do you know if you’re allergic to dog fur and dander? A skin prick test can tell you.
Skin prick tests will tell you whether your skin reacts to dog dander, while a blood test will give you a more comprehensive look at your allergy reactions.
Dog Allergy Blood Test Cost
Blood tests for dog allergies tend to cost somewhere between $200 and $1,000. Whether your insurance will cover this depends largely on your insurance company and plan. If cost is a big concern, you’ll probably want to go with a skin allergy test, which has a much lower cost of somewhere between $60 and $300.
Dog Allergy Dander Blood Test Results
A blood test will look at your dog dander IgE levels to establish whether you have a dog allergy. If you have elevated levels of these antibodies, the test will indicate that you have a dog allergy as opposed to some other type of allergy.
Can You Be Allergic to Dogs But Not Show Up on Allergy Blood Test?
A blood test will check whether your blood has IgE antibodies that respond to specific substances. Specific IgE antibodies indicate a specific allergy. The original testing method, called RAST, has now been replaced by a different type of blood test called ELISA.
What’s the dog allergy blood test accuracy rating? This type of testing is considered to be very accurate by experts in the medical field. In some cases, skin tests might react with more sensitivity than a blood test. However, skin tests can be affected by medications a person is taking. Blood tests aren’t affected by this extraneous data, so they can be more accurate than a skin test.
Allergy Home Test Kit
In the past, people needed to go to the hospital or doctor’s office to get tests done. However, a new product called MyAllergyTest has been FDA-approved to diagnose allergies at home. This test can screen for 10 common allergies at once.
To do the test, you’ll prick your finger and draw out a bit of blood. The sample will then be mailed to the ImmuneTech partner lab, the lab belonging to the company that created the test. After the sample is analyzed, the results will become available online. In addition, you’ll have access to an individualized allergy management plan that helps with treatment and long-term prevention.
Whether your allergies are caused by your dog or some other environmental trigger, it’s important to understand the source. When you know where the symptoms are coming from, you can take the appropriate steps to combat them.
