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.

Provide a pathology report with each tissue specimen. The laboratory will not reject a specimen that arrives without this information, but will hold the specimen until a pathology report is received.


Specimen Type: Paraffin-embedded tissue block

Collection Instructions: Submit formalin-fixed, paraffin-embedded tumor tissue block and include 1 hematoxylin and eosin-stained slide.

Acceptable: 3 unstained, 5-micron-thick sections mounted on positively charged microscope slides.

Additional Information: Advise Express Mail or equivalent if not on courier service.

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.

Tissue: paraffin-embedded whole tissue block or or onefour 5- micron thick sections mounted on positively charged microscope slides plus 1 hematoxylin-and-eosin eosin (H and E)-stained slide/Bone marrow: 1 mL
