What Tests Are Done To Determine Hay Fever
What tests are done to determine Hay Fever?
Physicians usually conduct various tests to identify hay fever apart from other allergies or complications that result from inflammation and irritation symptoms. These medical tests are briefly discussed in the following:
- Skin tests are performed to establish sensitive pollens that may cause such disease. This is performed through applying drops that contains small quantities of possible allergy-causing substances to the patient’s arm or back using a small plastic toothpick. In case the skin shows redness, swell, and becomes itchy after 20 minutes, the test has already identified the sensitive allergens.
- Blood tests such as the radioallergosorbent test (RAST) may also be conducted to measure the quantity of IgE produced by the immune system of the body to block different types of allergens.
- X-rays and other imaging tests may also be conducted to determine any possible causes or rhinitis such as probable structural abnormalities and other complications.

What are the main and common causes of Hay Fever?
Hay fever is usually triggered when an individual comes in contact with certain airborne particles which he is allergic to. These proteins can come from different sources, but it usually includes the following:
- The pollens, or small grains that are responsible for fertilizing a flowering plant, can easily be carried in the air. It can trigger different allergies which includes hat fever. These pollens are released by trees, weeds, and grass.
- Like pollens, molds and mildews can be easily carried through air. They usually grow areas with humid weather and less air circulation such as damp basements and bathrooms.
- Dust mites also triggers hay fever. These are microscopic insects that dwell in household dusts. They are commonly found on locations with less air circulation and on surfaces such as carpets and stuffed toys.
Pollens and molds are usually the common causes of hay fever, which when inhaled generate an allergic reaction. Although less common, allergic reactions are also triggered when these allergens are ingested or come in contact with the skin.
