 About Us

Flow CytometryOur Clinical Flow Cytometry Laboratory provides professional consultation and testing services to the UMass Memorial Medical Center and central Massachusetts Hospitals for the evaluation of potential leukemias, lymphomas, immunodeficiency, autoimmune disease, and a variety of other genetic, immunologic, hematologic, oncologic diseases and disorders.

The laboratory performs over 2150 tests per year.  Our routine tests include full leukemia / lymphoma panels and minimal residual disease testing, routine lymphocyte subset analysis, CD34 enumeration and PNH diagnosis.

Test results generally can be supplied in one or two days from receipt of sample, depending on the nature of the workup performed.  Flow cytometric results are available within hours if needed.
