Our Services


An Important Department Behind The Scenes

The Queen of the Valley medical laboratory is recognized as having a significant role in our delivery of quality patient care. Since medical laboratory professionals often work out of the public eye, few people know much about the critically important testing that the laboratory staff performs every day. It is estimated that approximately 85 percent of all physician decisions regarding diagnosis and treatment are based on laboratory test results.
