Flow Cytometry

Specimen Requirements

  • Peripheral Blood: 3-10 mL in green (sodium heparin) or lavender (EDTA) top tube

  • Bone Marrow Aspirate: 2-3 mL in green (sodium heparin) or lavender (EDTA) top tube

  • Malignant Fluids: 50-100 mL in collection pouch, depending on cellularity

  • Fresh Tissue Biopsy: In TRANSPORT MEDIA (RPMI)

  • Fine Needle Aspirate: in TRANSPORT MEDIA (RPMI)

  • Specimen must be refrigerated


Turn Around Time *

  • Approximately 24-48 Hours. TAT is variable as we do not perform this in-house


Special Instructions

  • Because Flow Cytometry is time sensitive, It is best to contact Central Oregon Pathology directly to schedule a pickup.

  • If you do not have RPMI, tissue may be submitted fresh (in saline) and we will place it in RPMI.








* Please note the information provided is intended as a guideline. Turnaround time is measured from the time of receipt of the specimen at our laboratory to the time the test result is made available to the client. As with all healthcare matters, the facts of a particular case may necessitate a turnaround time that is longer than stated above, the times mentioned above are our laboratory times for most, standard cases.
