LabCorp utilizes internal and external systems to oversee the integrity of testing methods and accuracy of results at their facilities, including quality organization programs, proficiency systems and integrity testing. The Burlington, North Carolina-based laboratory expert tests approximately 470,000 specimens each day, according to the website.
Quality assurance managers at LabCorp implement and monitor quality management programs at each respective location. The programs entail specific protocol for laboratory technicians to follow at every step of the pre-analytical, analytical and post-analytical processes. Computer programs aid in testing samples to increase accuracy and are regularly evaluated for effectiveness.
LabCorp employs internal proficiency testing to further ensure the accuracy of results produced within each facility, with each location subject to a quarterly proficiency audit. LabCorp also engages in over 20 external proficiency tests, administered by nationally recognized authorities such as the College of American Pathologists.
LabCorp also uses a two-part Specimen Integrity System (SIS) to help ensure accuracy. The Front End System involves a meticulous set of steps technicians must take in the collection of specimens and entering data, while integrating several processes that minimize the potential for errors. The Storage and Retrieval System streamlines the storage, splitting and tracking of specimens in an effort to prevent mistakes and inaccuracies.
