What are Allergies?

Allergies are when the body’s immune system has reactions to a substance that seems harmful to the body. Allergy symptoms can cause reactions that impact your breathing, eyes, and skin.

Allergies can affect children and adults. Seasonal allergies, known as hay fever, are due to outdoor allergens like pollen.

What are Allergens?

Substances that trigger allergic reactions is an allergen and is in various sources, such as:

  • Animal dander
  • Bee stings
  • Cosmetics
  • Dust
  • Food
  • Grass
  • Latex
  • Medication
  • Mold
  • Pollen

The substances are harmless to most people, but the symptoms can range from minor to more serious, depending on your allergy.

Your First Appointment

Appointment for Children

Allergy Testing

Depend on our experts to help you diagnose and manage both seasonal and chronic allergies. Testing includes:

Allergy Skin Testing

Allergy skin testing helps determine what allergens may be causing your symptoms. Common allergens include airborne allergens like (pollen, dust mites, pet dander, and molds, food, stinging insects, and medications.

Spirometry

Spirometry is a lung function test to help diagnose and treat asthma. It provides essential information on lung volumes and whether the patient has an airway obstruction (a narrowing of the bronchial air passages).

Allergy Patch Testing

Allergy patch testing helps understand what contact allergens may be causing your rash. Some examples include preservatives, pigments, metals, dyes, and fragrances. We may ask you to bring personal care products from home to test for individual products. Many common contact allergens are available in our office.

Patch testing takes four days from start to finish. On Monday, the office applies small test patches to your upper back. You must return to the office on Wednesday to have your care team remove the patches. Thursday is your final patch testing appointment. Avoid getting your back wet during this entire testing period.

Immune Testing

The initial testing includes reviewing your medical history to determine appropriate testing, which may include a blood draw. This information about your immune system health will assist with your care and treatment options. One treatment option is immunoglobulin therapy. This involves the replacement of antibody levels through IV or home SQ (under the skin) infusions.
