Necessary Information
1. Pathologist's name, address, and phone number are required.
2. Include accompanying pathology report stating the final diagnosis.
Specimen Required
Supplies: Pathology Packaging Kit (T554)
Specimen Type:
Preferred: Formalin-fixed, paraffin-embedded tissue block containing carcinoid/atypical carcinoid tumor of the lung including metastases.
Acceptable: 2 Unstained sections containing carcinoid/atypical carcinoid tumor of the lung including metastases on charged slides cut at 4 microns <1 month ago. Tissue on the slides should have been fixed in 10% neutral buffered formalin.
Container/Tube: Pathology Packaging Kit
Collection Instructions: Submit formalin-fixed, paraffin-embedded tissue block.

Clinical Information
Ki-67(MIB-1 clone) is a monoclonal antibody that reacts with cells undergoing DNA synthesis by binding to the Ki-67 antigen, a marker known to be expressed only in proliferating cells. By measuring the amount of tumor cells expressing Ki-67, an estimate of DNA synthesis can be determined. Studies suggest that Ki-67(MIB-1) analysis of paraffin-embedded tissue specimens may provide useful prognostic information in various tumor types.
Reference Values
Varies by tumor type; values reported from 0% to 100%
Cautions
The paraffin block analyzed must be representative of the patient's tumor.
Test results should be interpreted in the context of clinical findings and other laboratory data.
