5q-, -5 (5p15, 5q31, 5q33)
7q-, -7 (Cen 7, 7q22, 7q31)
Trisomy 8 (Cen 8)
p53 (17p13.1)/NF1 (17q11)
20q- (20q12, 20qter)
RPN1, MECOM (3q21, 3q26.2)
Optional Reflex (available with Global cases only):
ETV6 (12p13)
MLL (11q23)
+19 (19p13.2, 19q13)
when the main panel is negative.

Bone Marrow Aspirate: 1-2 mL in sodium heparin tube. EDTA tube is acceptable.
Peripheral Blood: 2-5 mL in sodium heparin tube. EDTA tube is acceptable.
Fresh, Unfixed Tissue: Tissue in RPMI.
Bone Marrow/Peripheral Blood Smear or Fresh Tissue Touch Preparation Slides: Minimum 4 slides, labeled with specimen type.
Fluids: Mix in equal parts with RPMI (specimen volume to RPMI ratio of 1:1).
Fixed Cell Suspension: A client-prepared fixed cell suspension is acceptable if received in 3:1 Methanol:Glacial Acetic Acid.
