Clinical Laboratories

The Clinical Laboratories at Yale-New Haven Hospital (YNHH) provide an extensive menu of routine, specialized and state-of-the-art laboratory tests to the patients who seek care at YNHH, but also provide reference testing to local physician practices, and to other hospitals and institutions in Connecticut, New England, and beyond.


The Directors and Assistant Directors of the Clinical Laboratories are faculty at the Yale School of Medicine and leading experts in their fields. Consultations are available for testing performed at Yale New Haven Hospital laboratories. For specific questions, contact faculty in the individual laboratories.
