Quality Policy
QUALITY POLICY
Nothing comes before quality. We are acutely aware that our patients and physicians are depending upon us to produce accurate, complete and timely laboratory results. We meet this need because we never forget that each specimen represents a person awaiting a laboratory report that they can trust to help in making important healthcare decisions. Proficiency testing, quality control, document control and quality assurance exercised at the pre-analytical, analytical and post-analytical stages ensure that each specimen receives the best quality testing that laboratory medicine offers.
Our commitment to quality is genuine and strong. Similarly, our commitment to compliance is based upon our belief that each person in our company will do the right thing every time, without compromise. We are pledged to this philosophy of ethical behavior and know that while this encompasses adherence to all applicable regulations and standards, it goes beyond what the law requires. Our commitment to our patients requires no less.
