Welcome to Longmont United Hospital (LUH) Laboratory’s combined “Services Directory.” Developed in conjunction with Mayo Medical Laboratories, our directory is intended to be a resource for anyone using our services. It was designed to provide complete information in the most accessible format, and we hope you find it an effective tool. LUH is dedicated to providing high quality laboratory services in the most responsive way. By providing timely and accurate laboratory results, LUH strives to assist healthcare professionals in delivery of quality patient care. Our three anatomic and clinical board-certified pathologists lead the laboratory staff of 65 medical technologists and laboratory assistants. We encourage comments and suggestions from all who use our services. It is this type of information that will allow us to further develop our systems and assure that our service is in line with the needs of our clients. We look forward to your continued input as we grow, expand services, and add new laboratory technology.
