Specimen
Immediately following collection, mix sample thoroughly by gently inverting 8 - 10 times, to prevent clotting
Dk green Sodium heparin (Na hep), no gel
EDTA whole blood (a chromosome analysis study is not recommended for this specimen type
Bone marrow
Collect bone marrow aspirate in a sterile Sodium heparin (Na hep) syringe and transfer to a sterile vial/tube
- or -
Collect bone marrow in sterile syringe (non-heparinized) and transfer to a Dk green Sodium heparin (Na hep), no gel
- Only one specimen tube is required to perform all ordered cytogenetics testing.
- The more testing requested, the closer to the optimal volume requirements is required.
EDTA whole blood:
Lavender (EDTA), 4mL
Bone marrow:
Sterile vial/tube
Dk green Sodium heparin (Na hep), no gel
- AHL Cytogenetics oncology request
Ambient
- Improper label (unlabeled or mislabeled)
