05/13/1998

TETERBORO, N.J., MAY 13, 1998-Quest Diagnostics Incorporated (NYSE: DGX) announced today that its specialty testing laboratory and research and development center, Nichols Institute in San Juan Capistrano, California, is the first national clinical laboratory in North America to successfully achieve ISO 9001 certification.

The ISO 9000 series was first recognized in the European Community. It was developed by the International Organization for Standardization, located in Geneva, Switzerland, to define business processes which, if followed, ensure that organizations meet internationally agreed-upon standards of quality. After an organization applies for ISO registration, independent auditors conduct an exhaustive inspection to verify the applicant’s quality systems and documentation against the published standards for all business operations, including the organization’s non-technical functions.

The ISO 9001 designation awarded to Quest Diagnostics’ Nichols Institute is the most comprehensive level of certification, encompassing quality management and document control systems for design, development and performance of diagnostic clinical laboratory testing, information and services.

Kenneth W. Freeman, Chairman and Chief Executive Officer of Quest Diagnostics, said, "We are proud of the achievement our Nichols Institute team has attained, representing nearly two years of diligent effort. It further demonstrates our strong commitment to delivering the highest quality services to our customers. The certification is particularly important as demand grows for leading-edge molecular testing for infectious diseases, oncology and genetics."
