Pathology & Laboratory Medicine

Pediatric Pathology

The division of Pediatric Pathology, under the direction of Jason Jarzembowski, MD, PhD, has a full-time faculty of seven board-certified pathologists, six of whom have subspecialty boards in Pediatric Pathology, and one Neuropathology. Three clinical PhDs serve as directors of Microbiology/Virology, Immunology, Clinical Chemistry, and Molecular Diagnostics. The division’s faculty also includes four PhD basic scientists.

In addition to excellence in general pediatric anatomic and clinical pathology, the CHW/CSG Division of Pediatric Pathology has nationally and internationally recognized expertise in a number of fields, including diagnosis of pediatric solid tumors, perinatal and placental pathology, pediatric and adult vascular anomalies (vascular tumors and malformations), pediatric cardiac and gastrointestinal pathology, pediatric cytopathology, nerve and muscle pathology, pharmacogenetic testing, biochemical genetic testing, and molecular diagnosis of infectious and inherited disease.

Clinical Service

The division provides a full range of subspecialized pediatric testing through the Children’s Hospital of Wisconsin (CHW) Clinical Laboratories, under the accreditation of the College of American Pathologists:

  • The CHW Clinical Chemistry Lab performs comprehensive biochemical testing for metabolic disorders as well as routine chemical analyses.
  • The CHW Microbiology Lab utilizes state-of-the-art MALDI-TOF identification of organisms and molecular detection of pathogens in collaboration with the CHW Molecular Diagnostics Lab, which also performs pharmacogenetic analysis as well as unique assays for coagulopathy and congenital hearing loss.
  • The CHW Hematology Lab includes routine blood counts and testing incorporating automated screening through Cellavision technology, bone marrow analysis including flow cytometry for leukemias and lymphomas, and coagulation assays such as rapid thromboelastography (TEG).
  • The CHW Histology Lab performs a variety of routine, special, immunohistochemical, immunofluorescent, and in situ hybridization staining for surgical pathology, cytopathology, and autopsy cases. Comprehensive muscle and nerve biopsy analysis are performed in the CHW and MCW Neuromuscular Laboratories.
