T-Cell Panel

Additional Info

  • Methodology: Flow Cytometry
  • Test Description:

    Markers:  CD1a, CD3, CD45, TCRαβ, TCRγδ, TdT

    The T-Cell Panel by flow cytometry is used to aid in the diagnosis of T-cell leukemias/lymphomas. This panel is best used in combination with the Leukemia/Lymphoma Panel.

  • Specimen Requirements:

    Bone marrow aspirate:  2-3 ml in green top (sodium heparin) or purple top (EDTA) tub
    Peripheral blood:  5-7 ml in green top (sodium heparin) or purple top (EDTA) tube
    Incisional/excisional or core needle biopsy:  Ideally, 1 cm3 of tissue completely immersed in RPMI. Testing can be successfully performed on smaller specimens if the tissue has adequate cellularity. If RPMI is unavailable, tissue can be submitted wrapped in saline-moistened gauze but not submerged in saline.
    Fine needle aspirate (FNA):  1:1 ratio of aspirate and RPMI; minimum 2 ml total

  • Storage & Transportation:

    Specimens should be received within 24-48 hours from collection to ensure sample integrity and acceptable cell viability. Peripheral blood and bone marrow aspirate specimens should be stored and transported at room temperature. Other tissue biopsies and body fluids should be refrigerated but not frozen; please use a cold pack to transport these specimens, making sure the cold pack is not in direct contact with the specimen.
