HelpTest Code PCPRO Plasma Cell DNA Content and Proliferation, Bone Marrow
Performing Laboratory
Mayo Clinic Laboratories in Rochester
Reporting Name
Plasma Cell Proliferation, MarrowSpecimen Type
Bone MarrowOrdering Guidance
This test can be ordered at diagnosis or follow-up of a plasma cell neoplasm (plasma cell proliferative disorder).
If CSMRT / mSMART Plasma Cell Proliferative Disorder, Pre-Analysis Cell Sorting, Bone Marrow or MPCDS / mSMART, Plasma Cell Proliferative Disorder, FISH, Bone Marrow is desired to be performed at Mayo, order MSMRT / Mayo Algorithmic Approach for Stratification of Myeloma and Risk-Adapted Therapy Report, Bone Marrow.
The Multiple Myeloma: Laboratory Screening algorithm will allow plasma cell fluorescence in situ hybridization (FISH) testing to be added, based on this test's flow cytometry results.
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.

Useful For
Establishing a diagnosis of a plasma cell proliferative disorder
Providing prognostic information for newly diagnosed multiple myeloma and other plasma cell proliferative disorders
Assessing response to therapy and detecting disease relapse and progression in treated plasma cell proliferative disorder patients
Determining plasma cell DNA content and proliferation
Testing Algorithm
When this test is ordered, flow cytometry interpretation will always be performed at an additional charge.
