Test ID: TFE3
Alveolar Soft Part Sarcoma (ASPS)/Renal Cell Carcinoma (RCC), Xp11.23 (TFE3), FISH, Tissue
Specimen Type
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.
Container/Tube:
Preferred: Formalin-fixed, paraffin-embedded tissue block
Acceptable: 5 unstained, 5-micron thick sections
Collection Instructions: Include 1 hematoxylin and eosin-stained slide.
Forms: If not ordering electronically, submit a Cytogenetics Hematologic Disorders Request Form (Supply T607) with the specimen.
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.
Paraffin-embedded whole tissue or four 5-micron thick sections plus 1 hematoxylin and eosin slide
