Test ID: 19701    
Biliary Tract Malignancy, FISH Only

Specimen Type Describes the specimen type needed for testing

Mixed

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 aspirate, bile duct brushing, hepatobiliary aspirate, or hepatobiliary brushing

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

Specimen Volume: Entire collection

Collection Instructions:

1. If performing local cytology before processing specimen, aliquot half of the specimen into another ThinPrep vial.

2. Retain 1 aliquot for local cytology and submit the second aliquot for analysis at Mayo Medical Laboratories.

3. Submission of the residual specimen (after processing for cytology) may compromise the sensitivity of the test.

Forms: If not ordering electronically, submit a Pathology/Cytology Request Form (Supply T246) 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.
