Quest Lab Stewardship

Empowering health systems to optimize laboratory testing and deliver high-value care

Laboratory testing is the single highest volume medical activity in the United States with somewhere in the range of 4-5 billion tests performed each year in the U.S.1 Too often, an inappropriate test is selected, redundant tests are ordered, or a needed test is omitted.2,3

That lab testing activity represents US$73 billion of the US$3 trillion spend on healthcare in the United States—about 2.5%.1

With laboratory tests guiding up to 70% of all medical decisions, improvements in appropriate test selection in compliance with evidence-based guidelines have the power to radically improve patient outcomes and reduce healthcare costs.3

Quest Lab Stewardship powered by hc1 can help.
