Sorrento Therapeutics’ Clinical Laboratory Receives Accreditation From the College of American Pathologists

Sorrento has received accreditation from the American College of Pathologists, which allows Sorrento to bill to Medicare and MedicaidSAN DIEGO, Dec. 07, 2021 (GLOBE NEWSWIRE) — Sorrento Therapeutics, Inc. (Nasdaq: SRNE, “Sorrento”) today announced the Accreditation Committee of the College of American Pathologists (CAP) has awarded accreditation to Sorrento’s Clinical Laboratory, located in San Diego, California, based on results of a recent on-site inspection as part of the CAP’s Accreditation Programs. Sorrento’s clinical laboratory was advised of this national recognition and congratulated for the excellence of the services being provided. The clinical laboratory is one of more than 8,000 CAP-accredited facilities worldwide. This accreditation expands Sorrento’s previously announced CLIA capabilities to include billing to Medicare and Medicaid for the analysis of patient samples. Additionally, with the CLIA certification and CAP accreditation of its clinical laboratory, Sorrento has the capability to conduct timely clinical studies to support its product pipeline across all stages. The U.S. federal government recognizes the CAP Laboratory Accreditation Program, begun in the early 1960s, as being equal-to or more-stringent-than the government’s own inspection program. During the CAP accreditation process, designed to ensure the highest standard of care for all laboratory patients, inspectors examine the laboratory’s records and quality control of procedures for the preceding two years. CAP inspectors also examine laboratory staff qualifications, equipment, facilities, safety program and record, and overall management. About the College of American Pathologists As the world’s largest organization of board-certified pathologists and leading provider of laboratory accreditation and proficiency testing programs, the College of American Pathologists (CAP) serves patients, pathologists, and the public by fostering and advocating excellence in the practice of pathology and laboratory medicine worldwide.
