Preferred Specimen
3mL Lavender EDTA
Minimum Volume
Whole blood: 3 mL
Bone marrow: 0.5 mL
Bone marrow: 0.5 mL
Instructions
Whole blood/bone marrow: Collect whole blood or bone marrow in an EDTA (lavender-top) tube and ship refrigerated or room temperature. Stability of whole blood and bone marrow samples at room and refrigerated temperature is 7 days. Fixed tissues (acceptable): 1 paraffin block (preferred) or 12 unstained sections on glass slides labeled with surgical case number (pathology report required, indicate if fixative is not formalin). Paraffin blocks are to be shipped at room temperature. Stability for paraffin blocks is indefinite. Do not freeze. Fresh/unfixed tissue samples (acceptable): Ship frozen on dry ice in tube labeled with specimen source and surgical case number; include preliminary pathology report. Frozen tissue is stable for approximately 1 year at -70°C. For tissue samples, fresh frozen tissue is preferred and to be shipped frozen. Frozen tissue is stable for approximately 1 year at -70°C. Tissues in formalin fixative or RPMI are to be shipped at room temperature or refrigerated. Needle washings (acceptable): In alcohol based fixative (eg. CytoLyt) are acceptable. Please include pathology report for all fresh FNA, frozen tissue and FFPE cases (partial/preliminary reports acceptable).
