Expected Turnaround Time

5 days
Stated turn-around-times (TATs) are for clinical use only and subject to change based on biopharma protocol requirements. Final TATs will be specified in the biopharma study contract.

Clinical Information

FISH testing on paraffin-embedded cells for detection of IGH::BCL2 gene fusion. This fusion, associated with t(14;18), is frequently observed in B-cell malignancies, including follicular lymphoma and diffuse large B-cell lymphoma (DLBCL). Often ordered as part of the FP BURKITT Panel test.

Specimen Requirements

FFPE Tissue Block
Unstained FFPE tissue: 5 slides preferred (3 slides minimum) cut at 3-5 μM and mounted on positively charged slides.

Specimen Stability

Stable indefinitely

Storage Requirements

15°C to 25°C

Shipping Conditions

Ambient

Shipping Recommendations

AMBIENT, Use a refrigerated (NOT FROZEN) gel pack in the shipment to protect from extreme temperatures. Separate gel pack from specimen. Do not freeze.

Specimen Rejection Criteria

Improper fixative; Tissue not fixed; Insufficient tissue; Specimen exposed to extreme temperature

Synonyms

IGH/BCL2; t(14;18)(q32;q21)

Test Method

Fluorescence in situ hybridization (FISH)

Methodology Category

Regulatory Status

ASR

Special Considerations

Tissues should be fixed in 10% neutral buffered formalin (NBF). Tissues preserved in B+ fixative or decalcified are usually not suitable for FISH. Assay requires 3 unstained slides minimum (two for each probe) and one H&E stained slide. If unstained slides are sent, cut FFPE tissue sections at 3-5 μm thickness, mounted on positively charged slides.

Associations

B-cell lymphoma (BCL), Non-Hodgkin lymphoma (NHL), Follicular lymphoma (FCL)
