Cytogenetics, Corewell Health Advanced Technology Laboratory – Grand Rapids, is now offering in-house testing for Biliary Tract Malignancy by FISH.
Bringing this testing in-house will reduce turn-around time for results by eliminating the travel time for send out testing.
Biliary Tract Malignancy testing by fluorescence in situ hybridization (FISH) is useful in assessing bile duct brushing or hepatobiliary brushing specimens for biliary tract malignancy. FISH can be used to detect cells with chromosomal changes (eg, aneuploidy) that are indicative of malignancy. Studies have indicated that the use of FISH to detect malignant cells in biliary brush specimens is useful as a screening tool, in addition to conventional cytology.
