Allergy Testing

Why Choose Florida Hospital?

Allergy testing is used to determine what substances may be causing a person to experience an allergic reaction. Many substances may directly impact a person, so an allergy diagnosis can help a patient to understand what possible triggers are causing allergy symptoms to flare up. An allergy test uses three methods to screen patients with possible allergies, which may show how the skin directly reacts to allergens. If the patient is allergic to a particular substance or multiple particles, the skin may react within minutes for one test or take 3 to 4 days for another. Allergists and immunologists at Florida Hospital are trained to perform allergy testing and may locate substances that cause patients adversely respond.

Allergy testing is used to locate the allergens that may be causing a patient to experience symptoms such as sneezing, watery eyes, coughing, skin rash, itchy skin and a number of other reactions which can make this condition especially frustrating in common cases. However, allergy testing may determine if a patient has a reaction to any medication, has a food allergy or if there is a particular venom that poses a threat to developing a more serious allergic reaction that requires emergency medical attention.
 
Three allergy tests that are most common in allergy are skin-based and may include the following: 
  • The skin prick test - pricking the skin with a small sample of an allergen that is suspected of causing allergy symptoms. This substance is placed under the skin and may take 15-20 minutes to respond, if in fact the patient is allergic to this substance. 
  • The intradermal skin test - this test involves injecting a small amount of a particular substance using a needle that is positioned to only inject under the skin rather than inside the body. The allergist will monitor the patient for a reaction to the substance. This type of test is ordered when drug and venom allergies are suspected. If any allergy exists, then the patient will react within the initial testing.   
  • Patch testing - this test is performed by taping various substances to the skin for a period of 48 hours. A patient will return back to the Allergy/Immunization clinic in 72 to 96 hours (3-4 days) to determine if the test is positive. Typically, the skin will react to this substance and show signs of an allergy.
