Collection Processing Instructions

Acceptable specimens include: Fresh Tissue (in sterile RPMI-1640, Hank's Balanced Salt Solution, Cytogenetics Transport Media, or sterile saline); or Body Fluids (submit in sodium heparin). If tissue is large, cut into several smaller pieces.  Specimen must arrive in Flow Cytometry within 36 hours of collection. Notify Flow Cytometry (800-222-5835, ext. 16385) of specimen arrival in lab. Cells in specimen must be viable.​

 Blood and Bone Marrow: Notify Flow Cytometry Laboratory (800-222-5835, ext. 16385) before sending the specimen.  Specimen must arrive within 48 hours of collection.  Cells in the specimen must be viable.  

Provide CBC and Differential results and 1-2 (stained or unstained) EDTA slide(s) (preferably from within 1 week of collection of specimen for Flow Cytometry Immunophenotyping).  Markers are selected based upon available clinical history and morphology per pathology protocol.
