Test Overview

Test Methodology

Fluorescence In Situ Hybridization (FISH)

Test Usage

This test detects aneuploidy of chromosomes 3, 7, and 17 via fluorescence in situ hybridization (FISH) in bile duct brushing and aspirate specimens. Detection of chromosomal gains is associated with malignancy. As an adjunct to conventional cytology this test may be useful in the assessment of pancreatobiliary strictures for malignancy.

Reference Range

Interpretive report provided.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Specimen Requirements

Collection

Obtain bile duct brushing or aspirate. Place brush directly into a ThinPrep (Non-Gyn) or conical tube containing CytoLyt solution, swirl the brush vigorously in the solution, then snip into the container, or place aspirate specimen into CytoLyt container. Refrigerate.
