Test Overview
Fluorescence In Situ Hybridization (FISH)
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.
