TO THE EDITOR, Evidence suggests that laboratory resources are being inappropriately used, resulting in avoidable costs for the healthcare system. Inappropriate testing can harm patients by causing hospital-acquired (iatrogenic) anemia and increasing the risk for transfusion, infections, missed or delayed diagnosis, additional unnecessary interventions, and incidental findings. Overuse of testing can also cause discomfort and stress for patients while creating additional workload for staff, increasing costs, and having an environmental impact. In this context, numerous interventions have been published aiming to improve the appropriateness of laboratory testing, including gatekeeping interventions. [...]
