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: Tissue
Preferred: Formalin-fixed, paraffin-embedded tumor tissue block
Acceptable: Seven consecutive, unstained, 5 micron-thick sections placed on positively-charged slides
Collection Instructions: Include 1 hematoxylin and eosin-stained slide.
1. New York Clients-Informed consent is required. Please document on the request form or electronic order that a copy is on file. An Informed Consent for Genetic Testing (Supply T576) is available in Special Instructions.
2. If not ordering electronically, complete, print, and send a Oncology Test Request Form (T729) with the specimen (www.mayomedicallaboratories.com/media/customer-service/forms/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.
Formalin-fixed paraffin-embedded tissue block or 3 consecutive unstained tissue sections cut at 5 microns placed on positively charged microscope slides and 1 hematoxylin and eosin stained slide
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
