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 reason for referral with each specimen. The laboratory will not reject testing if this information is not provided, but appropriate testing and interpretation may be compromised or delayed.
Advise Express Mail or equivalent if not on courier service.
Forms: If not ordering electronically, submit a Hematopathology/Molecular Oncology request form (Supply T241) with the specimen.
Submit only 1 of the following specimens:
Specimen Type: Tissue block
Collection Instructions: Submit formalin-fixed, paraffin-embedded tumor tissue block.
Specimen Type: Slides
Collection Instructions: Submit 2 consecutive, unstained, 5 micron-thick sections placed on positively-charged slides and 1 hematoxylin and eosin-stained slide.
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.
1 Hematoxylin and eosin-stained slide and 1 unstained slide
Note: No specimen should be rejected. If specimen not received at appropriate temperature, include note to laboratory. If questions, contact laboratory.
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
