Dk green Sodium heparin (Na hep), no gel

  
Bone marrow
EDTA whole blood (a chromosome analysis study is not recommended for this specimen type
  

EDTA whole blood:

Lavender (EDTA), 4mL

 

  
Bone marrow - 10 mL (minimum 5 mL)
  

Bone marrow

Collect bone marrow aspirate in a sterile Sodium heparin (Na hep) syringe and transfer to a sterile vial/tube

  

- or -

Collect bone marrow in sterile syringe (non-heparinized) and transfer to a Dk green Sodium heparin (Na hep), no gel

 

  • Only one specimen tube is required to perform all ordered cytogenetics testing.
  • The more testing requested, the closer to the optimal volume requirements is required.

Normal or Abnormal with interpretation

Standard Risk mSMART 3.0 abnormalities include:

  • a trisomy result of 5, 9, or 15 (or a combination of these)
  • a t(6;14) (CCND3/IGH) rearrangement
  • a t(11;14) (CCND1/IGH) rearrangement.

High Risk mSMART abnormalities include:

  • a t(4;14) (FGFR3/IGH) rearrangement
  • a t(14;16) (IGH/MAF) rearrangement
  • a t(14;20) (IGH/MAFB) rearrangement

Of note, one high risk abnormality may be ameliorated by a trisomy finding.

Double Hit Myeloma: Any 2 high-risk abnormalities present

Triple Hit Myeloma: 3 or more high risk abnormalities present
