Biliary Tract Malignancy, Cytology and Molecular Testing

Specimen Type Describes the specimen type needed for testing


Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Specimen Type: Bile duct brushing, bile duct aspirate, hepatobiliary brushing, or hepatobiliary aspirate

Container/Tube: Separate ThinPrep vial containing 20 mL PreservCyt or CytoLyt solution (Supply T536) for each specimen

Specimen Volume: Entire collection

Collection Instructions: Label with site specimen was collected from (eg, right hepatic duct or common bile duct).

Forms: If not ordering electronically, submit a Pathology Test Request Form (T246) with the specimen or complete, print, and send a Oncology Test Request Form (T729) with the specimen (

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

20 mL

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected








Pancreatic mass, cyst, or fine-needle aspiration (FNA)

Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
