Trisomy 12
Use
FISH test on hematologic specimens for detection of Trisomy 12. Trisomy 12 is a common recurring chromosomal defect in chronic lymphocytic leukemia (CLL). It has been reported in 15–30% of cases and is correlated with atypical morphology.
Special Instructions
All attempts will be made to process and report samples received > 72 hours post-collection. Bone marrow is the sample of choice in most heme malignancies.
Limitations
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. Specimens are subject to rejection if they are clotted, exposed to extreme temperatures, contain anticoagulants toxic to cells, or have an insufficient number of cells.
