New peanut allergy tests points to great over-diagnosis in kids


Quote:
Peanut allergies often necessitate warnings, including this one that isn't so serious, so people know to stay away.

As many as 12 percent of kids test positive for allergies to some of the most common food allergens, like peanuts. But a new, more accurate test reveals that many of those allergies are actually to a pollen, and not the dangerous food allergy that parents fear.

New research finds that we may be over-diagnosing, and over-treating, food allergies in kids.

According to researchers at Stanford University, five to 12 percent of kids test positive for allergies to milk, shrimp, peanuts or eggs, but less than three percent actually have allergic reactions to those foods.

Deborah Kotz, a reporter for the Boston Globe, said a new blood test, the uKnow Peanut Molecular test, is given to kids suspected of having peanut allergies. It turns out, with the new test, doctors can determine they do have allergies, but more likely to a birch pollen, rather than peanuts.

The new test is wonderfully helpful for telling the difference between "true" food allergy and food reactions that relate to oral allergy syndrome.

But I don't like the "great over-diagnosis" angle and the implication at the top of the story that anyone's been suggesting 12% of kids are peanut allergic.

That's not true, it's almost always reported as 1 to 2 percent for peanut allergy, with up to 8 percent of kids having top 8 allergies.
