A new study says some children previously diagnosed with peanut allergies may no longer be allergic, according to NBC News and The Washington Post. NBC described the finding as applying to many babies diagnosed with the allergy. The Post reported that children who received a diagnosis should be tested later, and said they are likely not to have an allergy after all.

The reports do not give the number of children in the study, the timing of follow-up testing or details about how the study assessed allergy. They also do not describe what tests should be used or say whether families should change a child’s care before testing. The reported recommendation is to have children retested later.
