Top-notch laboratory services

As an academic medical center, we are held to a higher standard of care and service.

Our progressive laboratory services deliver a comprehensive test menu, state of the art diagnostic methods, rapid turnaround, and expert consultative services not generally offered by commercial laboratories.

Delivering these services locally ensures continuity of care to the patients we serve. In addition, these services are available to the medical community at large through our outreach services.


We provide Phlebotomy Services at University Physicians Center. Home phlebotomies can be arranged when necessary.

Anatomic Pathology laboratories and services

Our Division of Anatomic Pathology provides a full spectrum of surgical pathology and cytopathology services. Special histochemical, immunofluorescent, and immunoperoxidase staining (e.g., staining for estrogen and progesterone receptors and Her/2 neu on breast biopsies; panels of antibodies for evaluation of tumors of unknown origin; lymphoma panels) and electron microscopy are available.

Cases are welcome for expert consultation or second opinion in the areas of hematopathology, dermatopathology, neuropathology, pediatric, pulmonary, renal, gynecologic, head and neck, bone, breast, and gastrointestinal pathology.

Decedent Care Services (DCS) is devoted to handling a decedent's affairs in a sensitive, confidential, and efficient manner.

The Decedent Care team is dedicated to providing support and assistance during the most difficult time for families and staff. Founded in 1970, the PSHMC DCS was modeled after programs at the University of Iowa and Case Western Reserve. DCS has provided support for the Department of Pathology and the hospital at large for more than 40 years. Through DCS, services that might be performed by as many as six other hospital units are combined into one central service, providing control and efficiency over the death care process.

We strive to provide guidance and support for family members and hospital staff, ensuring that all actions in the continuum of care are administered with confidentiality and respect. We provide technical and logistical support so that all parties have positive outcomes within an efficient time frame.

The team consists of a medical director, administrative manager, supervisor, and two full-time and four part-time decedent care associates (DCAs). Our 24 hours a day, 365 days a year operation provides quality services around the clock.

The DCAs are trained professionals who provide a calm and supportive presence during an emotional and potentially stressful time. Each DCA has mortuary- or science-related backgrounds and degrees.

The DCS team works collaboratively with multiple departments and organizations to communicate information that’s essential to the process that takes place after a death.

Prior to family contact, a DCA reviews the patient's medical record and demographic data to become familiar with information such as who is the legal next of kin. If necessary, the DCA will contact the County Coroner to determine and assist with jurisdiction.

The DCA meets with the clinician to discuss death certification and case options, which may include autopsy consent.

Autopsy services

An autopsy is a dignified and detailed surgical examination of the body after death that provides diagnostic information to the family and treating physicians. Autopsy findings usually validate major clinical diagnoses and may refine or clarify clinical data. Occasionally, an autopsy reveals important unexpected information about a patient's disease or condition. Autopsy information is a vital component of education and continuous quality improvement.

Autopsies are performed without charge to family members of a deceased in-patient. An autopsy may be performed without charge on an established Hershey Medical Center patient who passed away at home or in a care facility. All autopsies are performed by pathologists, physicians with specialized training in laboratory medicine. A typical autopsy requires three to six hours and should not delay or restrict funeral arrangements.

If an autopsy is requested, the DCA will assist the next of kin in completing an informed consent and discussing any limitations they wish to impose on the autopsy.  Autopsies are also performed for contracted hospitals.

Other services we provide include assistance with:

  • Organ/tissue donation: In accordance with PA Act 102, DCAs report the death to an organ/tissue donor agency and assist in the initial screening to determine donor suitability and maintain a record of the event. If donation consent is obtained, the DCA often assists the agency and the next of kin in the completion of the consent and then coordinates transfer of the patient for the procedure.
  • Family agent interaction: The DCA will meet with the next of kin to obtain contact information and identify who the family's agent for disposition will be: funeral home, cremation or body donation service. They will assist with initial contact and coordinate timely release of the patient's remains.
  • Research support service: DCS provides technical support for research programs within and outside of the medical center and is a regional neural tissue harvest center.
  • Liaison service: DCS provides referral, communication and assistance with various organizations including but not limited to: Coroner, Police Department, State Department or Foreign Embassy, Pennsylvania Department of Health, Bureau of Vital Statistics, Military Commanding Officer, Red Cross, Center for Medicare and Medicaid Services.  In house communication includes but not limited to: Medical Records, Infection Control, Bed Management, Risk Management and Quality Services.
  • Education: The Decedent Care Center staff and pathologists are dedicated to enhancing knowledge of families, physicians, nurses, health care students, chaplains and other allied health personnel.
