Eureka AlertThe Eureka Alert website has recently published an article explaining that siblings may not necessarily share the same food allergies. It has been a common mindset that when one of the siblings has a food allergy, chances are the others would have the same too. According to a new research, this is not entirely the case.

This article was published on their website:

SAN ANTONIO, TX (November 5, 2015) – If one child in a family has a food allergy, the reasoning sometimes goes, chances are good that siblings might also have food allergies. Not necessarily, according to new research which shows that 53 percent of siblings of children with food allergies had a food sensitivity, but only 13 percent had actual food allergy.

According to a study presented at the American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting, food allergy testing in siblings of kids with food allergies should be limited to decrease the negative consequences of a potential misdiagnosis.

“Too often, it’s assumed that if one child in a family has a food allergy, the other kids need to be tested for food allergies,” said Ruchi Gupta, MD, MPH, lead study author and ACAAI member. “But testing for food allergies if a reaction hasn’t taken place can provide false-positives, as we saw in our research. More than half the kids in the study had a sensitivity to a food, but they weren’t truly allergic. Kids who have a food sensitivity shouldn’t be labeled as having a food allergy.”
