•  Atopy Patch Testing:  (APT) Atopy Patch testing is a diagnostic tool used by some allergists to test reactivity for Non-IgE allergies by applying small disks with the food allergen placed under it on the surface of the skin (often the back). APT has not been universally accepted at this time and should be considered for use as a research tool rather than a standard test; it is not commonly used. Please see section 4.2.2.5 of the 2010 Guidelines for the Diagnosis and Management of Food Allergy in the United States for more details on patch testing in allergies.  More

  • Endoscopy: A procedure performed by a gastroenterologist to exam the upper gastrointestinal tract with a small scope: esophagus, stomach, upper small intestines; this may ordered to rule in/rule out specific medical conditions.  More
  • Food trialA food trial is a term used to refer to the process of offering a specific single-ingredient food to an infant/child for the first time. Generally, the food is given for a set period of days (i.e. for a full week, etc.) and in increasingly larger amounts with each day of the trial. The goal is to offer a full, age-appropriate serving of the food on the final day of the trial. If the infant/child does not appear symptomatic in relation to the food by the end of the trial, the food is generally considered safe. An infant/child’s doctor can help parents to determine an appropriate food trial length for him/her based on his/her age and reaction history.
  • Oral Food Challenge (OFC): A test, to be completed under medical supervision, to find out if a food is tolerated to either: a) confirm presence of allergy to suspected food; or b) to assess if allergy has been outgrown. More
  • RAST: An acronym that stands for radioallergosorbent test (also known as the Allergenspecific IgE antibody test), this is a blood test done to evaluate IgE antibody responses in the blood in regards to specific allergens. A detailed description can be found in section 4.2.2.4 of the 2010  Guidelines for the Diagnosis and Management of Food Allergy in the United StatesMore
  •  Sigmoidoscopy: Procedure performed by a gastroenterologist to exam the lower colon; this may be  ordered to rule in/rule out specific medical conditions. More

  • Upper GI Series: A test ordered by a doctor to rule out anatomical abnormalities in the upper gastrointestinal (GI) system that may be contributing to symptoms.  The patient ingests a barium solution and undergoes a series of x-rays to exam various components of the upper GI system. More
