Is a category 1 wheat allergy dangerous?

Can't tell: Allergy blood tests (rasts) are often ranked by class 1, class 2 and so forth, usually up to 6. This reflects the amount of allergic antibody present. However, many other things go into determining whether you will react when eating the food, or how severe the reaction will be. Predicting the severity of the reaction depends on your history, and may require a food challenge.

Wheat allergy: If you mean you received a class i grade on an allergy blood test, probably not. Most significant food allergies have a class iii or higher grade. The readings don't always relate precisely to severity, though. With most mild food allergies(no history of anaphylaxis), we advise the person to try eliminating the positive food for 1-2 weeks and then try eating it to see if symptoms can be provoked.
