SLUCare's hematopathologists offer a broad range of diagnostic services, with specialized techniques available through the extensive laboratory resources of Saint Louis University. We utilize state-of-the art equipment and extensive antibody resources to provide comprehensive diagnostic testing and achieve excellence in diagnosis.
As the oldest hematopathological service in the St. Louis area and an academic-based hemopathology service, our diagnostics are based on a continuous review of published reports about the latest clinical technologies.
Flow Cytometry: The Flow Cytometry Laboratory maintains an extensive panel of monoclonal antibodies.
The service utilizes state-of-the-art Beckman Coulter Cytomics FC 500 flow cytometers and recently updated software. Studies can be performed on peripheral blood, bone marrow, body fluids, fine needle aspirates or fresh tissue. A smear, cytospin or touch preparation is made of each specimen to confirm a suitable specimen and to tailor a specific antibody panel. A preliminary clinical diagnosis is required on the requisition.
Immunohistochemistry: Immunoperoxidase stains are available for immunophenotyping of lymphoproliferative processes, as are enzyme cytochemical stains for use in subtyping of acute leukemias.
Related Studies Available in Pathology at SLUCare
Gene rearrangement and translocation studies, which may be needed to detect monoclonality, are completed in the DNA Diagnostic Laboratory.
Ultrastructural studies may be useful to define cell origin of a malignancy. This advanced service is done in the electron microscopy laboratory.

Blood samples should be drawn in green top sodium heparin tubes, kept at room temperature and sent ASAP within 18 hours.
Bone marrow should be drawn in a heparinized syringe, placed in a green top sodium heparin tube, kept at room temperature and also sent within 18 hours.
Body fluids should be drawn in sodium heparin tubes and sent at room temperature.
Fresh tissue (0.5 cm) should be kept cold (on ice) and moist with saline soaked gauze, and transported within two hours; otherwise, it should be transported in RPMI media on wet ice to preserve the tissue. Please call for information on RPMI if needed. Flow cytometry cannot be performed on frozen or fixed (evenly briefly) tissue.
