Test ID: CTCP    
Circulating Tumor Cells (CTC) for Prostate Cancer by CellSearch, Blood

Specimen Type Describes the specimen type needed for testing

Whole blood

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 must be shipped immediately to ensure processing can be completed within 96 hours of draw. Send specimen Monday through Friday only and not the day before a holiday.

 

Container/Tube: Circulating Tumor Cell Collection Kit (Supply T630) containing CellSave tubes

Specimen Volume: 15 mL in 2 CellSaves tubes each containing 7.5 mL

Collection Instructions: Send specimen on same day of draw.

Additional Information: Date and time of draw are required.

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.

7.5 mL
