The cytopathology division of the Department of Pathology at North Shore-LIJ Health System offers state-of-the-art technologies and a complete test menu including conventional and ThinPrep Pap Test, fine needle aspirations and circulating tumor cell search. The pathologists in the department play a vital role in the diagnosis, treatment and monitoring of gynecologic, urologic, thyroid, pulmonary and pancreatic conditions, AIDS, and infectious diseases.


For more than 25 years, the cytopathology laboratory has provided accurate diagnoses for the community, serving patients and physicians. More than 80,000 specimens are processed and analyzed every year by highly skilled laboratory personnel, cytotechnologists and experienced board certified cytopathologists with vast diagnostic experience. Our staff is involved in the education of residents and fellows, forging the new generation of pathologists.

The cytopathology division staff works as a team in providing excellent patient care by offering personalized customer service to patients and physicians and by continuous quality improvement.

Timely results

The diagnosis of fine needle aspiration and non-gynecologic specimens is completed in 24–48 hours and the Pap tests are completed in three days.

Special services

Fine needle aspiration (FNA) of palpable lesions is performed by cytopathologists offering the advantage of rapid preliminary diagnoses in the majority of cases. The nature of some specimens may require additional studies such as immunohistochemistry and flow cytometry. The organs most commonly aspirated are the lymph node, thyroid, salivary gland and breast. On-site microscope adequacy assessment is also offered to radiologists and endoscopists to ensure proper collection, triaging and cellular adequacy. The cytopathology faculty is expert in thyroid, pediatric, urologic and pulmonary disease, among others. Circulating tumor cells – FDA-approved testing used to monitor treatment response helps predict survival in patients with breast, prostate or colorectal cancer, prior to a new course of therapy and at follow-up.

We offer ThinPrep Imaging System, a semi-automated screening device that increases pap test accuracy. Specimens are collected in liquid-based fixative and processed as monolayer preparation. We also offer a complete non-gynecologic test menu for virtually any cytopathology specimens: urine, effusions, cysts, washings and brushings.

Second opinions are available to physicians and patients to confirm previously diagnosed cytopathology specimens.
