Test ID: RBCS    
Relative B-Cell Subset Analysis Percentage, Blood

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This test should be ordered only when percentages (relative distribution of B cell subsets within the total B-cell population) are needed for the reportable B-cell subsets. If both percentages and absolute counts are needed for the reportable B-cell subsets, order IABCS / B-Cell Phenotyping Profile for Immunodeficiency and Immune Competence Assessment, Blood.
