Test ID: RBCS
Relative B-Cell Subset Analysis Percentage, Blood
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Screening for humoral or combined immunodeficiencies, including common variable immunodeficiency (CVID), hyper IgM syndrome, among others, where B-cell subset distribution information is desired
Assessing B-cell subset reconstitution after hematopoietic cell (HCT) or bone marrow transplant
Assessing B-cell subset reconstitution following recovery of B cells after B-cell-depleting immunotherapy
Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| CVID | CVID Confirmation Flow Panel | Yes | No |
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.
