Plasma Cell Assessment, Blood
Method Description Describes how the test is performed and provides a method-specific reference
The plasma cell immunoglobulin (Ig) light chain restriction assessment is performed by 6-color flow cytometry using a single assay tube containing antibodies to kappa Ig light chain, lambda Ig light chain, CD19, CD38, CD45, and CD138. CD38 and CD138 are used to gate on the plasma cells and anti-kappa and anti-lambda are used to identify cytoplasmic Ig light chains. The flow cytometric screen will report the presence or absence of a detectable plasma cell population with Ig light chain restriction (clonality).(Unpublished Mayo method)

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
Specimens are processed Monday through Sunday and reported Monday through Friday.
