Test ID: SLL
Small Lymphocytic Lymphoma, FISH, Tissue
Testing Algorithm 
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
This test does not include a pathology consult. If a pathology consult is requested, PATHC / Pathology Consultation should be ordered and the appropriate FISH test will be ordered and performed at an additional charge.
Mayo Hematopathology Consultants are involved in both the pre-analytic (tissue adequacy and probe selection, when applicable) and post-analytic (interpretation of FISH results in context of specific case, when applicable) phases.
A charge and CPT code is applied for each probe set hybridized, analyzed, and reported.
If the patient is being tracked for known abnormalities, indicate which probes should be used.
Panel includes testing for the following abnormalities using the probes listed:
6q-, D6Z1/MYB
11q-, D11Z1/ATM
+12, D12Z3/MDM2
13q-, D13S319/LAMP1
17p-, TP53/D17Z1
t(11;14), CCND1/IGH
When an IGH rearrangement is identified, reflex testing will be performed to identify the translocation partner. Probes include identification of t(14;18)(q32;q21) IGH/BCL2 and t(14;19)(q32;q13) IGH/BCL3.
This assay detects chromosome abnormalities observed in paraffin-embedded tissue samples from patients with small lymphocytic lymphoma. For testing blood and bone marrow of patients with chronic lymphocytic leukemia, order CLLF / Chronic Lymphocytic Leukemia (CLL), FISH.
Specimen Type Describes the specimen type validated for testing
Advisory Information
This test is not appropriate for testing blood and bone marrow from patients with chronic lymphocytic leukemia, order CLLF / Chronic Lymphocytic Leukemia (CLL), FISH.
Shipping Instructions
Advise Express Mail or equivalent if not on courier service.
Necessary Information
A reason for referral and pathology report are required in order for testing to be performed. Send information with specimen. Acceptable pathology reports include working drafts, preliminary pathology or surgical pathology reports.
Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Submit only 1 of the following specimens:
Specimen Type: Lymph node
Preferred: Tissue block
Collection Instructions: Submit a formalin-fixed, paraffin-embedded (FFPE) tumor tissue block. Blocks prepared with alternative fixation methods may be acceptable; provide fixation method used.
Acceptable: Slides
Collection Instructions: For each probe set ordered, 2 consecutive, unstained, 5 micron-thick sections placed on positively charged slides, and 1 hematoxylin and eosin-stained slide.
Specimen Type: Solid tumor
Preferred: Tissue block
Collection Instructions: Submit a formalin-fixed, paraffin-embedded (FFPE) tumor tissue block. Blocks prepared with alternative fixation methods may be acceptable; provide fixation method used.
Acceptable: Slides
Collection Instructions: For each probe set ordered, 2 consecutive, unstained, 5 micron-thick sections placed on positively charged slides, and 1 hematoxylin and eosin-stained slide.
Forms
If not ordering electronically, complete, print, and send a Hematopathology/Cytogenetics Test Request (T726) with the specimen.
Specimen Minimum Volume Defines the amount of sample necessary to provide a clinically relevant result as determined by the Testing Laboratory
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the performing laboratory, alternate acceptable temperatures are also included
