1.0 mL
  

Immediatley following collection, mix sample thoroughly by gentle inverting 8 - 10 times, to prevent clotting

  

Lavender (EDTA), 4mL

Varies; see Alternate collection instructions
  

Body fluid

  • Collect 20 mL (minimum 5 mL) of body fluid and place in a Falcon vial/tube - 15mL
    • Do not add anticoagulant or holding media
    • The volume required is dependent upon the white blood cell (WBC) count. Smaller volumes are sufficient if the cell count is high

Bone marrow

  • Collect 3 mL (minimum 1 mL) in a sodium heparinized (Na hep) syringe
    • Specimens collected in EDTA are acceptable, but not preferred
  • Transfer to an anticoagulant free sterile tube
  • If unable to collect a bone marrow aspirate, a bone marrow core placed in RPMI with Hepes, Pen Strep and FBS is acceptable

Cerebrospinal fluid (CSF)

  • Collect 5 mL (minimum 1 mL) in a sterile vial/container.
    • Do NOT add any anticoagulant or holding media
    • The volume required is dependent upon the white blood cell (WBC) count. Smaller volumes are sufficient if the cell count is high

Tissue

  • Immediately following collection, place the fine needle aspirate (FNA) or tissue in RPMI with Hepes/Pen strep/FBS -15 mL
