Allergy Testing Services

Allergy testing plays a critical role in identifying the substances that trigger allergic reactions and chronic symptoms. From seasonal allergies and food reactions to skin rashes and respiratory issues, understanding what your body is reacting to is the first step toward effective treatment and long-term relief.

At Schweiger Dermatology and Allergy, our board-certified allergists provide allergy testing services to help patients pinpoint triggers, reduce symptoms, and improve quality of life. Using evidence-based diagnostic methods, we evaluate allergies across all ages and develop personalized treatment plans based on accurate results.

Understanding Allergies and Why Testing Matters

Allergies occur when the immune system overreacts to substances that are typically harmless. These substances, which are called allergens, can be inhaled, ingested, injected, or absorbed through the skin. When exposure occurs, the immune system releases chemicals such as histamine, leading to symptoms that range from mild irritation to severe reactions.

Without proper allergy testing, symptoms are often misattributed to infections, stress, or environmental changes. Identifying the exact cause allows allergists to treat the root problem rather than just managing symptoms.

Common Allergy Symptoms

Allergy symptoms vary depending on the allergen and how the body is exposed. Common symptoms that may indicate the need for allergy testing include:

• Chronic nasal congestion, sneezing, or runny nose
• Watery, itchy, or burning eyes
• Persistent coughing or wheezing
• Skin rashes, hives, eczema, or itching
• Digestive discomfort after eating certain foods
• Reactions to insect stings or medications

If symptoms are recurring, worsening, or interfering with daily life, allergy testing can provide clarity and direction for treatment.

What Allergens Can Be Tested?

Allergy testing can identify reactions to a wide range of substances, including:

• Environmental Allergens: Pollen (trees, grass, weeds), mold, dust mites, cockroaches, and air pollutants.
• Food Allergens: Milk, eggs, wheat, soy, peanuts, tree nuts, shellfish, fish, and other foods.
• Animal Allergens: Pet dander, saliva, and proteins from cats, dogs, and other animals.
• Insect Allergens: Bee, wasp, hornet, yellow jacket, and other insect venom.
• Contact Allergens: Metals, fragrances, preservatives, cosmetics, chemicals, rubber, and topical products.
• Medication Allergens: Certain antibiotics and medications, evaluated under close medical supervision.

Types of Allergy Testing We Offer

Our allergists select the most appropriate testing method based on symptoms, age, medical history, and skin condition.

Skin Prick Allergy Testing

Skin prick testing is one of the most common and reliable allergy tests. Small amounts of allergen extracts are placed on the skin (typically the forearm or back) and the skin is lightly pricked. Results are evaluated within 15 to 20 minutes.

This test is commonly used to diagnose:

• Environmental allergies
• Food allergies
• Pet allergies

Skin prick testing is minimally invasive and well-tolerated by most patients.

Intradermal Allergy Testing

Intradermal testing involves injecting a small amount of allergen just beneath the skin’s surface. This method is more sensitive than skin prick testing and is often used when initial results are unclear.

Intradermal testing is commonly used for:

• Insect venom allergies
• Medication allergies

Because it is more sensitive, intradermal testing is performed selectively and under expert supervision.

Patch Testing for Contact Allergies

Patch testing is designed to identify contact allergies that cause delayed skin reactions. Small patches containing allergens are applied to the back and worn for 48 hours. The skin is then examined over multiple visits to detect delayed responses.

Patch testing is especially helpful for patients with:

• Chronic rashes
• Allergic contact dermatitis
• Suspected reactions to metals, fragrances, or chemicals

Blood Allergy Testing

Blood allergy testing measures specific IgE antibodies in the bloodstream that indicate allergic sensitivity. This option may be recommended for patients who cannot undergo skin testing due to widespread skin conditions, certain medications, or age considerations. Blood testing provides valuable insight into complex allergy profiles and may be used alongside skin testing.

What to Expect During an Allergy Testing Appointment

Your visit begins with a detailed consultation and medical history review. Our allergists discuss symptoms, timing, severity, family history, and environmental factors that may contribute to reactions.

A focused physical exam is performed, followed by allergy testing based on clinical findings. Testing is conducted in-office, and results are reviewed with you to ensure a clear understanding of what is causing your symptoms.

Allergy Treatment Plans

Once allergens are identified, our providers develop individualized allergy treatment plans designed to reduce exposure and control symptoms.

Treatment options may include:

• Prescription or over-the-counter medications
• Allergy immunotherapy (allergy shots or allergy drops)
• Environmental control strategies
• Emergency preparedness planning for severe allergies

Immunotherapy may be recommended for patients with persistent or severe allergies, helping reduce sensitivity over time and improve long-term outcomes.
