Testing

At Shepherd Allergy, we have multiple different types of testing to help ensure an accurate diagnosis. Dr. Shepherd will guide you on the best tailored approach.

Tests Offered

Skin Prick Test (Scratch Test)

A small amount of allergen is scratched onto the skin with a plastic testing device.
Intradermal Test

A small amount of allergen is injected under the skin with a small needle.
Patch Test

A patch sticker with allergens is applied to the skin for 48 hours and then read over time.
Blood Testing

This can be used to measure the amount of IgE, or “allergic protein”, in the body for various things such as environmental allergens and food.
Oral Food or Medication Challenge Test

This is an observed test done in the office where you are given small amounts over time of the suspected allergen.
Food Elimination Diet

This is a type of diet that involves removing specific foods for various time frames and keeping track of your symptoms.
Pulmonary Function Testing (PFT)

Spirometry is done to assess how much air you can breathe in and out and is sometimes performed with an inhaled medication to see how you respond to it.
Esophageal String Test (EST)

A non-invasive test designed to assess the degree of eosinophilic esophagitis (EoE) inflammation in patients. This innovative method allows us to monitor your response to medications and dietary changes without requiring an endoscopy (EGD).
