How do you get tested for cat allergies? - briefly
To determine if you have cat allergies, you can undergo skin prick tests or blood tests. These methods help identify specific antibodies produced in response to cat dander, providing a clear diagnosis of your allergy status.
How do you get tested for cat allergies? - in detail
To determine if you are allergic to cats, several diagnostic methods can be employed. The most common approach involves a combination of medical history assessment, physical examination, and specific allergy tests.
Firstly, your healthcare provider will gather a comprehensive medical history. This includes details about your symptoms, their onset and duration, any known exposure to cats, and the severity of your reactions. They may also inquire about any family history of allergies, as this can provide additional context for your condition.
Next, a physical examination is conducted. During this examination, the healthcare provider will look for signs of allergic reactions such as itchy or watery eyes, sneezing, runny nose, skin rashes, and any respiratory issues like wheezing or shortness of breath. Observing these symptoms can help in the initial diagnosis of cat allergy.
The most definitive way to confirm a cat allergy is through specific allergy tests. There are two primary types of tests commonly used: skin prick tests and blood tests.
Skin prick tests involve applying a small amount of an extract containing common allergens, including those from cats, onto the skin, usually on the forearm or back. The skin is then gently pricked with a sterile probe to allow the allergen to penetrate. If you are allergic to cats, you will develop a raised, red, itchy bump (wheal) at the test site within about 15-20 minutes. This reaction indicates a positive result for cat allergy.
Blood tests, on the other hand, measure the amount of immunoglobulin E (IgE) antibodies in your bloodstream. These antibodies are produced by your immune system in response to allergens. A blood sample is taken and sent to a laboratory where it is tested for the presence of IgE antibodies specific to cat allergens. The results, typically available within a few days to a week, will indicate whether you have an allergy to cats.
In some cases, your healthcare provider may also recommend a patch test. This involves applying a small amount of the allergen onto a patch that is then secured to your skin for a prolonged period, usually 48 hours. If you are allergic, a reaction will occur at the site where the patch was placed.
It's important to note that while these tests can provide valuable information about your allergy status, they should be interpreted in conjunction with your medical history and physical examination findings. Your healthcare provider will use this comprehensive approach to diagnose and manage your cat allergies effectively.
