In Reply: Drs Kirrane and Hoffman raise concerns about the validity of TESS data. TESS was used to identify most of the acute pesticide poisoning cases associated with school exposures that we reported. TESS data consist of telephone reports made to US poison control centers (PCCs). A vast majority of these calls are made by the patient or a family member. In our study, among the 2187 cases identified by TESS, only 7.5% involved reports made by health care professionals.
