  3. By proper allergy care, as asthma is considered an allergic condition, these deaths can be avoided.   
  4. Allergy testing can determine which specific allergen such as pollen, mold, or other substance is responsible for the overreaction of an individual’s body. 
  5. Hence, proper and specific medication or treatment is planned based on the allergen to avoid allergy triggers.

On rare occasions, the test done for allergy produces immediate and severe consequences that require medical attention as soon as possible. Due to these reasons, Allergy Testing should be performed in a medical office or lab where all the medical facilities are available including epinephrine that is used to treat anaphylaxis shock and save the patient from a life-threatening acute allergic reaction.

After Allergy Testing is completed, the doctor will determine the allergen and make a treatment plan that can avoid the overreaction caused to the body and their symptoms as well. The doctor can also suggest a few medications to get the symptomatic relief from the allergens.
