Scientists identify evidence-based predictors of biphasic reactions in kids

As a parent I find it damn scary that this can happen, and that I had no idea that this could happen. Granted, my kids only have minor allergies, so that may be it, but wow - two reactions to the same stressor, but one delayed compared to the other? Not something you like to have on your mind.

Children are more likely to have a repeat, delayed anaphylactic reaction from the same allergic cause, depending on the severity of the initial reaction.

A study led at the Children`s Hospital of Eastern Ontario (CHEO) Research Institute looked at the frequency and severity of biphasic allergic reactions.
