Preferred Specimen
Peripheral blood: 5 mL collected in a sodium heparin (green- top) tube, ACD-A (yellow-top) tube, or EDTA (lavender-top) tube or
Bone marrow: 4 mL collected in a sodium heparin (green-top) tube, ACD-A (yellow-top) tube, or EDTA (lavender-top) tube or
Tissue or body fluids: Any type is acceptable
Bone marrow: 4 mL collected in a sodium heparin (green-top) tube, ACD-A (yellow-top) tube, or EDTA (lavender-top) tube or
Tissue or body fluids: Any type is acceptable
Minimum Volume
3 mL peripheral blood • 1 mL bone marrow
Other Acceptable Specimens
Bone marrow: Pediatric heparin tube
Instructions
Peripheral blood and bone marrow: The tube must be kept at room temperature and shipped to the lab immediately.
Tissue: Any tissue type is acceptable. Tissue size is dependent upon leukocyte cellularity. (The tissue is disaggregated into single cells so that a minimum of 50,000 cells of interest are harvested.) Ship tissue in a sterile plastic container with RPMI 1640 enriched with FBS (10% FBS RPMI). Absolutely no fixative should be added. Refrigerate and ship immediately.
Body Fluids: Any body fluid is acceptable. Sample size is dependent upon cellularity of the sample. (A minimum of 50,000 cells of interest in total volume of fluid). Place fluid in sterile plastic container. Absolutely no fixative should be added. Refrigerate and ship immediately.

(2) A Query Tool login for the signout pathologist(s) through their client account. (3) Access to the web data portal on the signout pathologist's computer system and ability to view flow cytometry data in the FCS Express file format.
Do not freeze. Send specimen to testing lab for viability determination. All orders for this code from clients that do not meet the above criteria will be converted to the interpretive version of this panel.
Note: Any request for additional marker(s) must be communicated to laboratory within 48 hours of submitting sample and will delay results. Contact Oncology Services (866-677-0742) for further information on the qualification process described above.
A clinical indication and specimen source are required with each specimen. If possible, submit CBC results with differential or an EDTA tube of peripheral blood.
Do not freeze and do not place in fixative.
Because of the critical nature of these specimens, the laboratory will attempt to process all specimens received, regardless of age of specimen
