Specimen Collection Guide – Lymph Node/Tumor

2-3 mm2 Lymph Node or Tumor Biopsy in RPMI

Aseptically excise a small piece of lymph node or tumor 2-3 mm2 and place it in a sterile vessel containing sterile RPMI media (or less preferably, sterile saline if RPMI is not available). The specimen should be sent to the lab immediately. If unable to transport immediately, store at 4oC and transport at room temperature (15-25oC) within 24 hours.

Karyotyping and full analysis is only performed upon receipt of an order from a clinical Pathology laboratory.

Contact Cytogenetics for aliquots of RPMI for specimen collection, 519-685-8500 ext. 78974.

Note: All specimens should contain at least two patient identifiers and a completed requisition.
