HelpTest Code BILAO Biliary Tract Malignancy, FISH, Varies
Specimen Required
Supplies: PreservCyt Vial (T536)
Specimen Type: Bile duct brushing, bile duct aspirate, hepatobiliary brushing, or hepatobiliary aspirate (fine-needle aspiration is not acceptable)
Container/Tube: Separate ThinPrep vial, containing 20 mL PreservCyt or CytoLyt solution for each specimen
Specimen Volume: Entire collection
Collection Instructions:
1. If performing local cytology in addition to fluorescence in situ hybridization testing, aliquot half of the specimen into another ThinPrep vial before processing the specimen.
2. Submission of residual specimen (after processing other testing) may compromise the sensitivity of the test.
3. Label each specimen with specific source (eg, right hepatic duct or common bile duct).
