Our Commitment to Quality and Six Sigma
As the world's leading provider of diagnostic testing, information and services, Quest Diagnostics is leading the charge to raise the quality of healthcare delivery in the United States. Quality is not just our commitment it is our passion.
"At the heart of Six Sigma is the process that identifies behaviors that drive results for customers.
Six Sigma is a rigorous, data-centered approach to process improvement with the goal of delivering "virtual perfection" — meaning consistently high quality. Motorola first introduced Six Sigma in 1979 and companies such as General Electric and Allied Signal use it to dramatically reduce errors by trying to prevent them from happening in the first place. Quest Diagnostics began its Six Sigma journey in 2000 and is committed to being a Six Sigma Company in the eyes of its employees, customers and shareholders.
Quest Diagnostics has a heritage of focusing on quality. We are proud that Quest Diagnostics Nichols Institute was the first laboratory in North America to achieve ISO 9001 Certification in 1998.
Through our relentless focus on quality, we strive to provide our customers the highest quality products and services available; continuous improvement; and an unyielding desire to meet their requirements first time every time.
