Food Allergy Testing
& Assessment

Schedule a Food Allergy Assessment

Do you have a severe food allergy that requires safety precautions and specialized care, or are you potentially restricting foods that are safe and that you love? There is much confusion around food related reactions and what it actually means. Is it an allergy? Is it an intolerance? Is it a sensitivity? The best way to truly understand what you are experiencing is by seeking an accurate diagnosis with a board certified allergist.

At Latitude, we clear up this confusion using a comprehensive approach that combines historical data, skin tests, blood tests, and — when necessary — oral food challenges to get the most accurate diagnosis possible.

What does the process look like?

Skin Prick Test

A very safe and low risk test where the skin is lightly pricked with an allergen. Our clinicians observe and measure the skin reactions to determine possible allergens. The reactions typically present as hives or bumps. The larger the hive, the more likely it is to be a true allergy. Skin testing can cause itchiness.

Blood Test

A test that measures the levels of IgE antibodies in the patient to a specific food. Blood draws can be done on site at some Latitude locations and will be sent to an off-site lab for processing. Our phlebotomist can see patients of all ages and specializes in blood draws for babies and children. Blood draws can also be done at a local Quest or LabCorp lab.

Component Test

A blood test that can also be used to help diagnose food allergies such as peanut, tree nuts, milk and egg. Peanut components help determine the different protein fragments and reactions to each protein such as ARA H1, ARA H2, and ARA H3 and can provide more clarity to the clinician. Milk and egg components help determine if a patient can tolerate baked milk or egg.

Oral Food Challenge

This is considered the gold standard for diagnosing a food allergy. After analyzing all the data including patient history, skin test and blood test, our allergist might determine that a food allergy has been outgrown or is not present and recommend a food challenge to help the patient determine, with certainty, if they are or are not allergic to a specific food. The challenge will only be done if the clinician believes that it is safe and that the patient is likely to pass. Under close observation, very small amounts of the food are given in increasing amounts over a 3 to 4 hour time period. This test is especially important if you have an unclear medical history or if your skin and blood tests are not conclusive.

In combination with your patient history, a physical examination, and food allergy tests, Latitude’s board certified allergists can help provide you with an accurate diagnosis.
