Credentials with Practitioner Descriptions

Modern medicine would be impossible without the complex tests performed in the medical laboratory. Laboratory professionals are responsible for conducting tests that result in the diagnosis, treatment, and prevention of disease. The following practitioner descriptions provide brief insight into the many professionals for which the American Society for Clinical Pathology Board of Certification (ASCP BOC) provides credentials.
