Describes the specimen type needed for testing
Tissue
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: 7 consecutive unstained 5-micron thick sections placed on positively charged slides
Collection Instructions: Include 1 hematoxylin and eosin-stained slide.
Forms: 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
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
