Histocompatibility

Phone:  717-531-5118

Medical Director: Ronald E. Domen, M.D. 
Associate Director: Hiroko Shike, M.D.

  • The Histocompatibility Laboratory performs all Histocompatibility testing required for solid organ and bone marrow transplant programs. This testing consists of state-of-the-art serological and molecular typing for all W.H.O. recognized antigens of the HLA A, B, C, DR and DQ loci. In addition, various types of white cell crossmatching and antibody screening are performed to determine whether or not a potential transplant recipient has antibodies directed against HLA antigens, and in particular, those of a specific donor.

This laboratory provides centralized Histocompatibility services for the entire region served by the Gift of Life donor transplant program.

  • HLA typing (at a nominal cost) for individuals that volunteer as potential donors for the National Marrow Donor Program. HLA tissue typing is also requested for Disease Association studies, when the presence or absence of a particular antigen is informative, e.g. HLA B27 in ankylosing spondylitis.

 

Virology

Phone:  717-531-5121

Medical Director: Wallace H. Greene, Ph.D., D(ABMM)

  • The Clinical Virology Laboratory offers a comprehensive service for viral isolation, rapid direct detection with viral diagnostic assays and viral serologies.
  • The lab offers technical and scientific expertise and support by working closely with the health care provider to determine the most appropriate and cost effective course of action. The laboratory is in operation Monday through Friday, 0800 - 1630 hours, Saturday 0800 - 1200 hours and Sunday 1300 - 1600 hours.
  • All positive results are telephoned to the requesting physician. Special instructions in collection techniques are provided by the virology staff. In addition all viral collection supplies provided at no cost.
  • We offer isolation and identification for the following viruses: adenovirus, cytomegalovirus, enterovirus, herpes simplex virus, influenza virus, parainfluenza virus, mumps, measles, rotavirus, respiratory syncytial virus, and varicella-zoster virus.
  • Molecular diagnostic assays for chlamydia and Neisseria gonorrhea are available.
  • Because our virology lab is within the medical center we achieve optimal sensitivity with viral cultures due to decreased transport times. We are also readily available for on-site or phone consultations.
