Optimal Volume:Entire intact specimen
Container:Plastic leakproof container, sterile
Collection Instructions:If frozen section or special studies (e.g., immunohistochemistry, electron microscopy, tissue culture) are contemplated, contact Surgical Pathology for appropriate technique or fixative The volume of fixative should be 10-15 times the volume of tissue. The container should be large enough to allow specimen removal after hardening by fixative.

Biopsies taken in Patient Care Units and Clinics:
  • Place specimen in fixative immediately upon removal  10% neutral buffered formalin is suitable for most purposes.
  • When a special study is contemplated such as enzyme histochemistry, electron microscopy, immunohistochemistry, tissue culture, or biochemical determination, contact pathologist-on-call to identify the appropriate technique and fixative for the procedure. Some specimens for special procedures must be hand-delivered.

Biopsies taken in the Operating Room:
  • Deliver organ or tissue specimens removed during surgery intact and unsectioned to Surgical Pathology Laboratory.
  • When sectioning of the specimen in the Operating Room is deemed necessary, contact Surgical Pathologist who will perform or oversee sectioning of the specimen.
  • When portions of a resected specimen are required for investigative studies (electron microscopy, tissue culture, immunology research, etc.), the specimen should be delivered first to Surgical  Pathology.The pathologist will, upon request, provide segments of the specimen for special studies.
  • When a culture must be taken from a specimen, it should be performed in the Operating Room where a sterile field exists before delivering the specimen to the laboratory.
  • Any large specimen that must be transported in a basin should be covered with a biohazard plastic bag.
