Clinical Info
|
Phenotyping by flow cytometry can aid in the evaluation of hematopoietic neoplasms in specimens including bone marrow, whole blood, tissue, or fluid. It facilitates lineage detection (i.e. B vs T vs myeloid) and in conjunction with morphologic and other ancillary findings, can provide a confirmatory diagnosis or differential diagnoses. Phenotyping may aid in monitoring response to therapy in individuals with an established diagnosis of hematopoietic neoplasms.
Markers are analyzed as needed, based on clinical evidence and history, as an initial screening panel. Additional markers are selected based on pathologist interpretation of the screening panel results to fully characterize any abnormalities identified by the screening panel.
Antigens included:
T/NK cell: CD2, CD3, CD4, CD5, CD7, CD8, CD16, CD56, CD57, TRCB-1, CD30, TCR gamma-delta, TCR alpha-beta, CD279, CD26
B cell: CD10, CD19, CD20, CD22, CD23, CD103, CD200, kappa, lambda, CD79b, FMC-7, CD103, cCD79a, cCD22
Myeloid/monocyte: CD11b, CD13, CD14, CD16, CD15, CD33, CD64, CD11b, CD117, myeloperoxidase, CD34
Plasma cell: CD138, CD38, cytoplasmic kappa and lamda, CD27, CD81, CD56, CD117
Miscellaneous: CD11c, CD123, CD41, CD61, CD71, TdT, CD36, CD42b, CD45, HLA-DR, TdT, CRLF-2
Poor cell viability may adversely affect antigens and compromise result accuracy and reliability.

Contact the Tumor Marker (Flow Cytometry) Laboratory at 516-562-4169 for collection instructions and consultation on selection of test(s).
Test for PNH is performed at Long island Jewish Flow Lab 718-470-3035 and requires two Lavender (EDTA) tubes - Done on Peripheral Blood Samples Only. Immediate Delivery to the Lab is recommended.
Submit only 1 of the following specimens:
Blood - Green-top (sodium heparin) tube or Lavender top (EDTA) tube. Recommended Amount: 3 mL whole blood (1 mL min)
Transport Temperature: Room Temperature Collection Instructions: Deliver specimen to laboratory within 12 Hours Note: 1. Indicate blood on request form . 2. Comment Rituximab Sensitivity on form
Bone Marrow - Obtain 3 mL of bone marrow in a green-top (sodium heparin) tube or lavender top (EDTA) tube. Forward promptly at ambient temperature. Deliver specimen to laboratory within 12 Hours
Note: 1. Indicate bone marrow on request form. 2. Label with Rituximab Sensitivity. Bone Marrow aspirate smears (recommend 4-6) must accompany all bone marrow specimens. Include Peripheral Blood Smear whenever possible.
CAUTION: If sending unstained slides as part of biopsy kit, please package slides separately outside of the biopsy box. Do not freeze.
CSF - 3mL desired in sterile container at Room Temperature. Do not freeze. Deliver to lab immediately is recommended. If needed, Refrigerate to
maintain 2-8°C.
Tissue - Obtain tissue in sterile Container and indicate the source - 0.5cm3 recommended. Recommended Storage medium - RPMI 1640 but Saline can be substituted. Transfer at Room Temperature. Do not
freeze. Deliver to the lab immediately. If needed, Refrigerate to maintain 2-8°C.
Body Fluid - Obtain 3-5mL Body Fluid in sterile container. Indicate Fluid type on the sample. Transfer at Room Temperature. Deliver to lab immediately is recommended. If needed, Refrigerate to maintain 2-8°C.
