Summary

This study will measure normal blood clotting values in 240 children under 18 who are having surgery or a procedure with anesthesia. The goal is to establish reference ranges for the Quantra system, a device that checks how well blood clots. This information will help doctors better understand and manage bleeding or clotting issues in pediatric patients.
