Castle Biosciences’ New Laboratory Receives Accreditation from College of American Pathologists


Expanded laboratory capacity addresses significant growth in test utilization

Friendswood, TX – January 17, 2017 – Castle Biosciences, Inc., a provider of molecular diagnostics to improve cancer treatment decisions, today announced that the Accreditation Committee of the College of American Pathologists (CAP) has awarded accreditation to its new state-of-the-art laboratory facility in Phoenix, AZ based on results of a recent onsite inspection as part of the CAP’s Accreditation Programs. CAP accreditation is awarded to facilities that meet the highest standards of quality in laboratory services. The 10,000-square-foot laboratory is also certified under the Centers for Medicare & Medicaid Services (CMS) Clinical Laboratory Improvement Amendments (CLIA).

“Our laboratory’s CAP accreditation achievement validates our commitment to providing high-quality molecular diagnostic tests to improve patient care in cutaneous melanoma, uveal melanoma and other underserved cancers,” commented Derek Maetzold, President and CEO of Castle Biosciences. “We expanded our lab capacity to help meet the rapid uptake by physicians of our innovative prognostic tests. Our DecisionDx-Melanoma test, which provides an individual risk of recurrence in patients with cutaneous melanoma, was used in more than 7,100 patients in 2016, a growth rate of more than 97% over 2015.”

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.
