Castle Biosciences Receives Accreditation from the College of American Pathologists for its Pittsburgh Clinical Laboratory

Castle Biosciences, Inc. (Nasdaq: CSTL), a company improving health through innovative tests that guide patient care, today announced that the Accreditation Committee of the College of American Pathologists (CAP) has accredited its clinical laboratory facility in Pittsburgh. This achievement follows a recent on-site inspection as part of the CAP’s Laboratory Accreditation Program.

“This important accreditation is reflective of Castle’s commitment to excellence, safety and quality, driven by our dedicated laboratory team,” said Kristen Oelschlager, chief operating officer of Castle Biosciences. “We are proud that clinicians and patients can use our innovative tests knowing that our clinical laboratories have received this accreditation reserved for laboratories operating under the high standards required by CAP.”

The CAP Laboratory Accreditation Program was started in the early 1960s and is recognized by the U.S. federal government as being equal to or more stringent than its own inspection program. During the CAP accreditation process, inspectors examine the laboratory’s records and quality control procedures for the preceding two years. CAP inspectors also examine laboratory staff qualifications, equipment, facilities, safety program and record, and overall management. CAP accreditation is then awarded to facilities that meet the highest standards of quality in laboratory services. Once achieved, on-site inspections occur every two years to assess ongoing compliance with the CAP accreditation program requirements.

Castle acquired its laboratory in Pittsburgh through the acquisition of Cernostics, Inc. in December 2021, and subsequently initiated ongoing process improvements and laboratory expansion efforts. With this accreditation, all of Castle’s laboratories are now CAP accredited, reflecting the Company’s commitment to high-quality standards and excellence in patient care.
