Core Laboratory Phlebotomy

About Us

The Johns Hopkins Core Laboratory phlebotomy team is composed of approximately 70 well-trained phlebotomists, many of whom are nationally certified. This 24/7 team performs approximately 15,000 phlebotomies per month and provides centralized service for the 1,000-bed Johns Hopkins Hospital, the 550 phlebotomy site, and the Nelson 2 phlebotomy site.

Our Phlebotomists are an important members of the Johns Hopkins Healthcare Team whose primary function is the collection of peripheral blood samples from patients by venipuncture or a heel stick. The phlebotomist's responsibility is the collection and transportation of laboratory specimens, and is often the patient's only contact with the medical laboratory. We offer around the clock services to our patients to facilitate their needs. Through annual competencies and continuing education the department has helped to improve patient safety and patient care.
