Lymph node core biopsies
Unfixed lymph node samples can be sent either FRESH or in formalin. Lymph node cores, where lymphoma is suspected, the sample should be sent FRESH in an appropriately sized, labelled, dry container. Arrange in advance with the laboratory, telephone ext.58212 and arrange for the specimen to be transported to Histopathology immediately by a theatre porter. Routine specimens should be sent in formalin, immersed in six to ten times the volume of neutral buffered formalin (10%) in an appropriately sized container and the lid secured properly. The pot should be labelled with a formalin hazard label.
