Reduced Exhaled Breath Condensate pH and Severity of Allergic Sensitization Predict School Age Asthma.

Background: We previously reported that deaerated breath condensate pH (dEBC pH) can identify preschool children with recurrent wheezing at high asthma risk.

Objective: To assess the ability of preschool dEBC pH to predict asthma risk at school age.

Methods: Children of the baseline cohort were recontacted for follow-up.
