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.
