Test Code LAB3823 Plasma Cell DNA Content and Proliferation, Bone Marrow

Important Note

This test is orderable by pathologists only.

Reporting Name

Plasma Cell Proliferation, Marrow

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.

 

For more information see:

-Amyloidosis: Laboratory Approach to Diagnosis

-Multiple Myeloma: Laboratory Screening

Performing Laboratory

Mayo Clinic Laboratories in Rochester

Specimen Type

Bone Marrow


Ordering 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.
