What do the IgE reactivity levels, classes, and ranges mean?

Modified on Fri, 09 Dec 2022 at 03:45 PM

Reactivity level: The clinical interpretation of your test results. IgE reactivity is what is being measured in the lab. Healthcare providers or other allergy test brands may refer to this section as sensitization.


Classes: Provides insights into the severity of a suspected allergen. Each result will fall in a class, and each class will fall within a reactivity level.


Intensity ranges: The cut-offs that define the classes. Ranges are specific to the instrument measuring your IgE concentration in the lab.
