The GML Anatomic Pathology Subspecialties

Steven C. Meschter, MD

Led by Dr. Steven Meschter, the Geisinger Medical Laboratories Cytopathologists provide:

• State-of-the-art thin layer cervical screening preparation
  Computer-assisted review and reflexive HPV-DNA testing on ASCUS cases
• Expert review
  Fine needle aspirates, body cavity fluids, urine, and cerebrospinal fluid
• Advanced ancillary techniques
  Including flow cytometry, immunocytochemistry, and fluorescent in situ hybridization (FISH) which aid in establishing specific diagnoses
• Prompt, personal consultations
  Direct contact with submitting physicians.  We also provide cytohistologic correlations and maintain an extensive quality assurance program.

The cytopathology laboratories of the Geisinger Medical Laboratories process more than 84,000 cytology cases per year, of which approximately 6,150 are non-gynecologic cases. 

Gynecologic testing has gone high-tech in GML Cytopathology. The laboratory is fully automated and incorporates computer-assisted primary screening using the FocalPoint computer. This significantly improves the ability to detect premalignant epithelial lesions.

The laboratory routinely processes SurePath and ThinPrep liquid based cervical specimens. These thin layer technologies help to reduce the false negative rate of cervical cytologic screening. The laboratory offers expertise in the interpretation of specimens from multiple collection systems in order to provide flexibility and choice for our many outreach clients. Ancillary testing for high-risk HPV-DNA is offered on both liquid-based platforms.
