Ki-67 Tissue Assay, Paraffin : 0049270

Mnemonic: KI67 IP

Methodology: Immunohistochemistry
Performed: Mon-Fri
Reported: Within 5 days
Specimen Required: Collect:  Tumor tissue.

Transport:  Paraffin-embedded, formalin-fixed tissue block enriched with tumor at 20-25°C.  Protect paraffin block from excessive heat.  Ship in cooled container during summer months. Include surgical pathology report.

Unacceptable Conditions:  Paraffin block with no tumor tissue remaining; samples fixed in B-5 or Bouin's fixative.

Stability:  Ambient: Indefinitely; Refrigerated: Acceptable; Frozen: Unacceptable
Interpretive Data: The Ki-67 antigen is used to estimate the growth fraction of a tumor cell population.  In many malignancies, a high Ki-67 value generally correlates with an aggressive behavior. Results of this test should be interpreted with caution on the context of other data.
Assay is performed on paraffin-embedded, formalin-fixed tissue.  Antibody clone is MIB-1 and the detection system is LSAB.
