Preferred Specimen
3 mL bone marrow collected in a sodium heparin (green-top) tube, ACD-A (yellow-top) tube, or EDTA (lavender-top) tube or
>0.3 cm fresh tissue in a sterile plastic container with RPMI 1640 enriched with FBS (10% FBS RPMI)
Minimum Volume
Other Acceptable Specimens
Instructions
Whole 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. 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. Place fluid in sterile, plastic container. Absolutely no fixative should be added. Refrigerate and ship immediately.
Do not freeze. Send specimen to testing lab for viability determination. Do not reject.
Note: Additional markers may be performed based on the pathologist review. These markers will be performed at an additional charge. Any request for additional marker(s) must be communicated to laboratory within 48 hours of submitting sample and will delay results.
A clinical indication and specimen source are required with each specimen. If available, submit CBC report with differential.
Because of the critical nature of these specimens, the laboratory will attempt to process all specimens received, regardless of age of specimen. Specimens received frozen or in fixative will be rejected.
