How do you know if you are allergic to cats?

Cat lovers tend to live with their allergies

When people know that the reason causing their allergies is from cats they love, undoubtedly they will be challenging to accept this truth. Therefore, instead of giving up taking care of their cats, they will choose to suffer symptoms.

Determining reason causing allergy to cats in the family may be quite difficult as other allergens like dust will cause similar symptoms. So, to determine the reason causing allergy, the essential thing is seeing a doctor.

Reason causing allergy

Allergy experts said that protein in cats’ furs, saliva, or dead skins is the reason causing the allergy. In other words, the problem causing allergy is not cats’ furs. Our immune system creates antibodies to fight against substances hurting bodies like bacteria and viruses. To people catching allergy, their immune system mistakes some allergens with something harmful and produces antibodies to fight. This is the reason causing allergy symptoms such as the runny nose, being itchy, asthma, rash, or sneezing.

According to researchers, in allergy development, being genetic plays a quite important role. It is the element increasing the risk of cat allergy. This means that if there are any members catching allergy in your family, you are more likely to be allergic. 

In the case of cat allergy, allergens can come from saliva, fur, or even urine of cats. Touching with allergens or breathing in cats’ hairs can cause an allergic reaction. Allergens can stick to air, clothing, bed, and furniture as well as stay in an environment like dust.  

Cats’ bodies often produce allergens (kinds of protein having the ability to cause allergy). These allergens appear on cats’ skins, furs, and saliva. Also, all researches prove that all allergens from cats can cause allergy to humans’ bodies. Meanwhile, all kinds of cats produce allergens.

Besides clinical symptoms, to diagnose cat allergy, doctors usually ask patients to implement these two subclinical tests. There are two types of skin tests. They are tests in skin and skin allergy tests. They not only give a result more quickly but also have a lower cost than the blood test. To know which test is the best for you, you should talk to the doctor.

  • Blood test: Doctors will ask patients to have a blood test if the skin allergy test does not bring any diagnostic results. The blood test can help to determine the sensitivity level of patients’ bodies with allergens. Moreover, this kind of test brings blood screening.
  • Skin test: This test helps to determine the reason causing allergy exactly. Doctors will use a small amount of pure allergic substances extracted from animal protein and inject it into the skin surface, usually on back or arm. After about 15 minutes, the medical staff will observe whether there are any signs of allergy reactions on the skin or not. They will see itchy and red swelling bumps on patients’ skins in case of cat allergy.
