Allergy Testing Q & A

What causes allergies?

Allergies occur when your immune system reacts to a substance in your environment and has decided that a particular allergen is harmful to you. Your immune system reacts to destroy it, causing allergy symptoms. Many allergies develop from repeated exposure to the allergen, and allergic reactions may increase in severity over time. If you find you react differently to changes in seasons or specific foods, it may be time for an allergy test.

What are common allergens?

Environmental allergies, including pollen, dust mites, mold, and animal dander, are especially common and can occur both indoors and outdoors. Other common allergens include:

  • Specific foods (peanuts, tree nuts, soy, eggs, milk, shellfish, fish, wheat)
  • Insect stings
  • Latex
  • Medications


How are allergies diagnosed?

Some allergies are easily diagnosed by paying attention to your surroundings when you feel the start of an allergic reaction. Other allergies are harder to identify and need professional insight. 

At Avant Allergy, Dr. Ho discusses your symptoms, including when and where they occur, along with taking a family history of allergic reactions. Allergy tests determine your specific allergens and diagnose common conditions such as allergy-induced asthma, hay fever, eczema, and food allergies. Common allergy tests include:

  • Patch tests
  • Skin prick tests
  • Drug tests
  • Food tests
  • Insect allergy tests


If you suspect you have an allergy, schedule an appointment with Avant Allergy to diagnose the allergens and determine an effective treatment.

What are the symptoms of allergies?

Allergic reactions occur when you come into contact with an allergen. The severity of allergy symptoms range from a seasonal nuisance to life-threatening anaphylaxis. The most common allergy symptoms include:

  • Inflammation
  • Sneezing
  • Runny nose
  • Skin rash
  • Itchy, watery eyes
  • Swelling
  • Shortness of breath 
  • Vomiting or diarrhea
  • Anaphylaxis



How do you treat allergies?

Antihistamines are the most popular treatment for allergies and many are available over the counter. Severe or chronic allergies benefit from a treatment method tailored to your allergen. Custom treatment plans may include prescription medication and immunotherapy, which exposes your body to the allergen in small amounts over an extended period. 

If you or your child is experiencing allergy symptoms, a diagnosis and treatment plan can significantly increase the quality of life and reduce symptoms. Call Avant Allergy or use the online booking tool to schedule an appointment for indoor and outdoor allergy testing today.
