Cutaneous Anaplastic Large Cell Lymphoma, 6p25.3 (IRF4) Rearrangement, 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.

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.


Submit only 1 of the following specimens:


Specimen Type: Lymph node

Preferred: Tissue block               

Collection Instructions: Formalin-fixed, paraffin-embedded (FFPE) tumor tissue block. Include 1 hematoxylin and eosin (H and E)-stained slide.


Acceptable: Slides

Collection Instructions: For each probe set ordered, 2 unstained consecutive tissue sections cut at 5 microns and placed on positively charged microscope slides. Include 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 2 consecutive unstained 5-micron thick sections placed on positive-charged microscope slides and 1 hematoxylin and eosin-stained slide.

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected

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.
