How Can Hay Fever Be Diagnosed
How can Hay Fever be diagnosed?
A physician usually conducts a physical examination and a review of medical history of the patient. This will reveal history of other allergies, asthma, and eczema which can raise the likelihood of a patient having hay fever. It will also show his family history and trace any instances of allergic rhinitis or other airborne allergies.
During the physical examination, the patient will be asked of the symptoms he is experiencing as well as the time of the year he experience such symptoms. It is relatively important since the season of the year affects the severity and existence of the disease.
The physician will also take into account the patient’s home environment, work environment, and hobbies as well. It will help him identify the allergens that trigger the symptoms. In addition, blood tests such as the radioallergosorbent test (RAST Test) are conducted in order to rule out any other potential causes of rhinitis such as 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.
