Biliary Tract Malignancy, Cytology and Molecular Testing
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
When this test is ordered, biliary tract malignancy testing by FISH will always be performed at an additional charge.
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).
1. Pathology/Cytology Information (T707) in Special Instructions
2. If not ordering electronically, complete, print, and send 1 of the following forms with the specimen:
Pathology Test Request Form (T246) (http://www.mayomedicallaboratories.com/it-mmfiles/pathology-request-form.pdf)
Oncology Test Request Form (T729) (http://www.mayomedicallaboratories.com/it-mmfiles/oncology-request-form.pdf)
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.
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.
