Intended Use
Alternate test to detect prognostically important genomic abnormalities in CLL. The genomic landscape of CLL is very heterogeneous, lacking a unifying genetic lesion. The most frequent chromosomal aberrations are del(13q), del(11q), (del(17p), and trisomy 12.
Specimen Required
- Bone Marrow: Transfer 3 mL bone marrow to a Green (Sodium Heparin). (Min: 1 mL)
- Whole Blood: Transport 5 mL whole blood. (Min: 2 mL)
Patient Preparation
- Sample collection: Non-diluted bone marrow aspirate. Collect in a sodium heparinized Vacutainer.
- Specimen preparation: Do not freeze or expose to extreme temperatures.
- Storage/Transport Temperature: Room temperature.
- Unacceptable Conditions: Frozen specimens. Clotted specimens.
- Remarks:
- Stability: Ambient: 48 hours; Refrigerated: 48 hours; Frozen: Unacceptable

Interpretive Data
Probes include: KMT2A(MLL)/11q del, Trisomy 12, 13q del (DLEU/LAMP1), TP53/17p del, ATM
The most recent WHO classification of Tumours of Hematopoietic and Lymphoid Tissues (Revised 5th edition) is used for interpretation criteria for evaluation.
