Sentinel Lymph Node Biopsy
See Specimen Submission Instructions for test requisition, specimen labeling and specimen packaging requirements.
If a sentinel lymph node procedure using radioactive isotopes is performed, please contact histology at (402) 465-1933 at least 24 hours prior to the procedure to ensure proper handling procedures for radioactive specimens are followed.
Specimens should be submitted in 10% neutral buffered formalin solution. Formalin containers must have a formalin hazard label on the outside of the container. The time the specimen is placed in formalin must be recorded on tissue requisition in the appropriate location. The amount of formalin should be ten times the volume of the specimen.
If the sentinel node is being sent for rapid intra-operative consultation at a hospital location then the specimen should be brought down to the pathology lab STAT by the Surgery staff. The specimen should be submitted fresh.
