1. Indications

Intracutaneous (intradermal) allergy tests are indicated for the evaluation of immediate hypersensitivity reactions to specific allergens. These tests are commonly performed in patients who exhibit symptoms suggestive of allergic conditions, including but not limited to:

• Allergic Rhinitis Symptoms such as sneezing, nasal congestion, and itchy eyes that may indicate an allergic response to environmental allergens.
• Asthma Patients with asthma may undergo testing to identify specific triggers that exacerbate their condition.
• Urticaria Individuals experiencing hives or skin rashes may require testing to determine the underlying allergens responsible for their symptoms.
• Food Allergies Testing may be indicated for patients with suspected food allergies to identify specific food allergens.
• Insect Venom Allergies Patients with a history of severe reactions to insect stings may be tested to identify specific venom sensitivities.

2. Procedure

The procedure for conducting intracutaneous allergy tests involves several key steps, which are outlined as follows:

• Step 1: Patient Preparation The physician begins by reviewing the patient's medical history and any previous allergic reactions. The skin is then prepared, typically by cleaning the area with an antiseptic solution to minimize the risk of infection.
• Step 2: Selection of Allergens The physician selects the specific drugs, biologicals, or venoms to be tested based on the patient's history and symptoms. The number of allergens tested is specified, as this is a critical component of the procedure.
• Step 3: Administration of Tests Using a fine needle, the physician injects small amounts of the selected allergens intradermally, which means just beneath the skin's surface. Each injection site is carefully marked to ensure accurate observation of reactions.
• Step 4: Observation After the injections, the physician monitors the test sites for a specified period, typically 15 to 20 minutes, observing for any immediate allergic reactions such as swelling, redness, or itching.
• Step 5: Interpretation of Results Following the observation period, the physician assesses the reactions at each test site. The results are documented, noting the presence or absence of reactions and their severity.
• Step 6: Reporting Finally, the physician compiles a written report that includes the number of tests performed, the specific allergens used, and a detailed interpretation of the reactions observed. This report is essential for guiding further management and treatment of the patient's allergies.

3. Post-Procedure

After the completion of the intracutaneous allergy tests, patients may experience mild reactions at the injection sites, such as localized redness or swelling, which typically resolve within a few hours. The physician may provide instructions for post-procedure care, including recommendations to avoid scratching the test sites and to monitor for any delayed reactions. Patients are advised to contact their healthcare provider if they experience significant discomfort or any unusual symptoms following the tests. The results of the tests will guide the physician in developing an appropriate management plan for the patient's allergies, which may include avoidance strategies or potential treatment options.
