The Division of Hematopathology in the Department of Pathology at North Shore-LIJ Health System is experienced in all aspects of the diagnostic evaluation of patients with hematologic disorders of the blood, bone marrow, lymph nodes and other tissues. This division uses immunohistochemical, flow cytometric and cytogenetic/molecular techniques to evaluate hematologic disorders. We also deliver the highest quality of clinical hematology laboratory services.

The Division of Hematopathology is committed to strong person-to-person working relationships with hematologists and oncologists. Our testing and consultation services assist treating physicians as well as hematopathologists confronted with difficult diagnostic problems in leukemia and lymphoma.

We are active in the teaching of hematopathology to pathology residents, hematology/oncology fellows (adult and pediatric), medical students and laboratory technologists. Our goals include expanding scholarly study of hematologic disorders and collaboration with those involved in research in this exciting subspecialty.


Many years of experience working closely with pathologists, as well as with the treating oncologists and hematologists, has enabled our hematopathologists to understand both the diagnostic complexities and the practical implications in this extremely complex area. We can help determine not only the most appropriate test for diagnosis, but also the circumstances in which additional costly testing may not be needed. We are always available to discuss the special features of any case.

Timely results

Test results generally can be supplied in one or two days from receipt of sample, depending on the nature of the workup performed. If requested, preliminary assessment can be given the same day. Flow cytometric results are available within hours, if needed. Phone reports are routine, and hard copy is usually available by fax the following day.

Special services

The Flow Cytometry Laboratory uses six-color multiparameter analysis to detect malignant hematopoietic cells in a manner most appropriate for classification.

The laboratory performs more than 5,000 tests per year on the flow cytometric analysis of hematologic disorders (performed on blood, bone marrow, lymphoid tissue, fine needle aspiration, body fluids and CSF, GI and skin biopsies). Other flow cytometric tests performed by the laboratory include routine lymphocyte subset analysis and CD34 enumeration.

Our hematopathologists also works closely with the Cytogenetics and Molecular Diagnostics Laboratories under the direction of Jordan Laser, MD, Associate Medical Director, Core Laboratory (Sr. Director, Division of Cytogenetics and Molecular Pathology) and Prabakaran Paulraj, PhD (associate director of cytogenetics).
