Myeloid Sarcoma, FISH, Tissue
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.
A pathology report is required with each tissue specimen. Indicate if the patient has a previously diagnosed myeloid leukemia. The laboratory will not reject specimens that arrive without this information but will hold the specimen until a pathology report is received.
Forms: If not ordering electronically, complete, print, and send a Hematopathology/Cytogenetics Test Request Form (T726) with the specimen (www.mayomedicallaboratories.com/media/customer-service/forms/hematopathology-request-form.pdf).
Submit only 1 of the following specimens:
Specimen Type: Tissue
Container/Tube: Formalin-fixed, paraffin-embedded tumor tissue block
Collection Instructions: Include 1 hematoxylin and eosin (H and E)-stained slide.
Specimen Type: Slides
Specimen Volume: For each probe set ordered, submit 2 unstained, consecutive tissue sections cut at 5 microns and placed on positively-charged microscope slides, and 1 H and E-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.
Formalin-fixed, paraffin-embedded tissue block or for each probe set ordered, 1 unstained consecutive tissue sections cut at 5 microns and placed on positively charged microscope slides, plus include 1 hematoxylin and eosin (H and E)-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.
