[Interpretation of the tuberculin test in children].

Tuberculosis is a resurgent disease in Spain. One of the most important reasons is immigration from countries in which this disease is highly endemic. The pediatric population is especially susceptible to adults with tuberculosis and an infected child represents a sentry event of recent transmission in the community. The tuberculin test is an essential instrument in the evaluation of this disease and therefore a determining factor in the therapeutic approach adopted. This document aims to clarify and unify criteria related to the techniques and interpretation of the tuberculin test in children in our environment.
