Allergy testing and treatment are important components of managing allergic conditions, which occur when the body's immune system reacts abnormally to substances (allergens) that are typically harmless to most people. Allergy testing helps identify specific allergens triggering allergic reactions, while treatment aims to alleviate symptoms and reduce allergic reactions.

Allergy Q & A

How are allergies diagnosed? 

There are several methods of diagnosing allergies. The method depends on the kind of trigger your provider suspects you have. 

Skin Prick Test

This common allergy test involves placing small amounts of various allergens (such as pollen, dust mites, pet dander, or food extracts) on the skin, usually on the forearm or back. The skin is then pricked or scratched to allow the allergens to enter the skin surface. If an allergic reaction occurs (such as redness, swelling, or itching) at the site of a particular allergen, it indicates sensitization to that allergen.

Blood Test (Specific IgE Test)

Blood tests, such as the ImmunoCAP test, measure the levels of specific IgE antibodies to various allergens in the blood. Elevated levels of IgE antibodies to specific allergens indicate sensitization to those allergens.

Patch Test

Patch testing is used to diagnose allergic contact dermatitis, a type of delayed hypersensitivity reaction to certain substances (such as metals, fragrances, or chemicals) that come into contact with the skin. During a patch test, small amounts of potential allergens are applied to patches, which are then placed on the skin (usually the back) for a period of time. Any skin reactions that occur indicate sensitization to those allergens.

Elimination Diet

For suspected food allergies or intolerances, an elimination diet may be used to identify trigger foods. This involves temporarily removing suspected allergens from the diet and then gradually reintroducing them while monitoring for symptoms.

How are allergies treated? 

Avoiding exposure to known allergens is often the first line of defense in managing allergies. This may involve making changes to the home environment (such as using allergen-proof bedding, air purifiers, or avoiding pets) or dietary modifications (such as avoiding certain foods).

If you have "allergies," it means your body's immune system is responding to a foreign substance that's not usually harmful. This response can cause a variety of symptoms, including itchiness, rashes, congestion, wheezing, sneezing, watery eyes, inflammation, and more. If you suspect you might have allergies, make an appointment at RescueMD for testing to relieve any bothersome symptoms.

You may also benefit from medications to address your allergy symptoms:


These medications help relieve symptoms such as sneezing, itching, and runny nose by blocking the effects of histamine, a chemical released during allergic reactions.

Nasal Corticosteroids

These nasal sprays help reduce inflammation and relieve nasal congestion, sneezing, and runny nose associated with allergic rhinitis.


Oral or nasal decongestants may be used to temporarily relieve nasal congestion associated with allergies.

Allergy Shots (Immunotherapy)

Allergy shots involve regular injections of small amounts of allergens over time to desensitize the immune system and reduce allergic reactions. Immunotherapy is typically recommended for individuals with severe allergies or allergies that do not respond to other treatments.

Sublingual Immunotherapy (SLIT)

SLIT involves placing drops or tablets containing allergens under the tongue to desensitize the immune system and reduce allergic reactions. SLIT is an alternative to allergy shots and may be used for certain types of allergies.

Emergency Medications

For severe allergic reactions (anaphylaxis), emergency medications such as epinephrine (EpiPen) may be prescribed to quickly reverse symptoms and prevent life-threatening complications.

How does the team at RescueMD help manage allergies? 

Individuals with allergies should work with their provider at RescueMD to develop an allergy action plan, which includes strategies for managing allergic reactions, identifying triggers, and knowing when to seek medical help.

Education about allergens, triggers, and management strategies is important for those with allergies and their caregivers. Support groups or resources may also provide valuable information and emotional support for managing allergies.

Overall, allergy testing and treatment play a crucial role in identifying allergens, managing symptoms, and improving the quality of life for individuals with allergic conditions. It's important for those with allergies to work closely with their healthcare provider to develop a personalized treatment plan tailored to their specific needs and circumstances.
