Test Code MSMRD Myeloma Stratification and Risk-Adapted Therapy with Reflex to Minimal Residual Disease, Bone Marrow


Ordering Guidance


This test should be ordered on patients treated for multiple myeloma to confirm remission has been achieved, as an annual follow-up of those in remission or in uncertain remission, or when MPCDS / mSMART, Plasma Cell Proliferative Disorder, FISH, Bone Marrow is desired.

 



Necessary Information


1. Include patient's disease state (untreated, treated, monoclonal gammopathy of undetermined significance, stable).

2. Indicate if patient is on anti-CD38 therapy.



Specimen Required


Specimen Type: Redirected bone marrow

Preferred: Yellow top (ACD solution A or B)

Acceptable: Lavender top (EDTA)

Specimen Volume: 4 mL


Secondary ID

616030

Useful For

Risk stratification of patients with treated multiple myeloma, which can assist in determining treatment and management decisions

 

Risk stratification of patients with newly diagnosed multiple myeloma

Reflex Tests

Test ID Reporting Name Available Separately Always Performed
CSMRT MPCDS Pre-Analysis Cell Sorting, BM No No
MPCDS mSMART Eval, PCPDs, FISH Yes, (Order PCPDS) No
MRDMR Multiple Myeloma MRD by Flow, BM Yes, (Order MRDMM) No

Testing Algorithm

Based on the flow cytometric analysis and the presence of greater than or equal to 0.1% monotypic plasma cells, pre-analysis cell sorting and fluorescence in situ hybridization for plasma cell proliferative disorders will be performed at an additional charge.

 

Based on the flow cytometric analysis and the absence of monotypic plasma cells, then minimal residual disease for multiple myeloma will be performed at an additional charge.
