Allergy Testing in Palm Harbor, FL

The initial step in the treatment of an allergy is an accurate diagnosis by an allergist or immunologist. It involves deciding whether the patient's symptoms are caused by an allergy and, if so, determining what triggers the allergy as accurately as possible. The resulting diagnosis will target the appropriate treatment or clinical intervention to allow avoidance of the allergic trigger which will help to eliminate or minimize symptoms.

Common Allergy Tests

Skin Prick Allergy Test - The skin is pricked by the allergist and a multitude of different allergens are placed on each part of the skin that gets pricked so it can get under the skin. You will wait 20 minutes and Dr. Berrios will look for swelling, redness, itching, or other signs of an allergic reaction. This is the most common test.

Intradermal Allergy Test

The intradermal allergy test is a specialized diagnostic procedure in which an allergen is injected just beneath the surface of the skin to assess whether a patient has an allergic reaction. This test is typically recommended for evaluating allergies that are not easily detected with other methods, such as the skin prick test.

When is an Intradermal Allergy Test Used?

This test is particularly useful for detecting allergies to:

• Certain medications, such as antibiotics (e.g., penicillin).
• Insect venom, including bee or wasp stings.
• Other allergens that might require deeper skin exposure to provoke a response.

It is often performed if:

• The skin prick test results are inconclusive.
• The allergist, such as Dr. Jose A. Berrios, suspects an allergy that wasn’t detected during initial testing.

What to Expect During the Test

• Preparation: Your skin is cleaned, usually on the forearm or upper arm.
• Injection: A small amount of the suspected allergen is injected just under the surface of the skin using a fine needle.
• Observation Period: After the injection, you will wait approximately 15–30 minutes for the allergist to monitor your skin for any signs of a reaction, such as swelling, redness, or a raised bump (wheal).

Benefits of the Intradermal Test

• Provides a more sensitive test for certain allergens compared to skin prick tests.
• Can help confirm allergies when symptoms or history strongly suggest a reaction but initial testing is negative.

Risks and Considerations

While generally safe, the intradermal allergy test carries a small risk of side effects, such as:

• Mild discomfort or itching at the injection site.
• Rarely, a more severe allergic reaction, which is why this test is always conducted in a medical setting with emergency care readily available.

Results and Next Steps

Dr. Berrios will review the results of the test and determine whether you have an allergy to the substance tested. Based on the findings, he will develop a personalized treatment plan, which may include allergen avoidance strategies, medications, or immunotherapy to manage your symptoms effectively.

Patch Allergy Testing

 This test is usually used to test skin reaction to allergens that touch the skin. Allergens are taped to the skin by an allergist for 48 hours, and Dr. Berrios will look at the area in 72-96 hours to look for reactions.

Blood Allergy Test

This test actually looks for changes in IgE antibodies, which are specific to allergic reactions, rather than just skin reactions.

An accurate diagnosis is obtained using a combination of approaches and tests that can include skin pricks and blood tests to identify and confirm a diagnosis. Treatments can include:

Controlling Symptoms of Allergies with Medication

These treatments can be self-administered and do not necessarily need to be based on an accurate diagnosis by an allergist. Examples include the use of over-the-counter medications such as antihistamine creams and steroid creams for eczema and antihistamine pills for nasal symptoms that include rhinitis and seasonal allergies. More serious conditions can be treated with inhalers for asthma, skin creams for eczema and auto injectors for anaphylaxis resulting from, among other causes, insect bites, without having identified whether the condition is truly an allergy.

Avoiding Allergens

This approach is used mainly for allergies caused by food, drugs, venom, latex, and animal dander. This can also include occupational allergies, and to a lesser extent, depending on the suspected cause, asthma, rhinitis, and eczema. When using allergen avoidance, it is important to know that there may be interactions resulting from cross reactions between, to name a few, latex and fruits and vegetables as well as tree pollen and fresh fruits. While it may appear simple, avoiding allergens may be difficult to achieve, costly, and may not be completely successful.

Rescue Medications

This approach is often part of an individual's emergency self-treatment plan for acute attacks such as acute tongue swelling or anaphylaxis that can result from insect bites.

Immunotherapy in Palm Harbor, FL

By administering an allergen either via a beneath the skin (subcutaneous) injection or under the tongue (sublingual) an allergist or immunologist can try to reintroduce a patient's immunological tolerance to a particular allergen. These procedures are typically used to treat allergies caused by pollen rhinitis, venom, asthma and cat allergy. On occasion, the use of drugs to desensitize a patient to a particular allergen can also be used.
