Document Summary

Midterm 1 mycourses reading 2: food allergy, a test called an oral food challenge is the gold standard to rule out an allergy. Then after 20 minutes or so, if you don"t have any reaction, you can take a dose that"s a little bigger. And about 20% of kids outgrow peanut allergies: researchers studied the results of about 6,300 food challenges. The tests were done in adults and children whom doctors suspected had become tolerant to foods they"d once reacted to: we found that 14% of the patients challenged had mild or moderate allergic reactions. If the symptoms were treated with just benadryl or another antihistamine, they were considered mild or moderate. 2% of the reactions were more serious, requiring treatment with epinephrine. But the vast majority of patients, 86 percent, did not have an allergic reaction: many of the patients in the study may have outgrown their allergy.
