Test ID: IABCS
B-Cell Phenotyping Profile for Immunodeficiency and Immune Competence Assessment, Blood
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Screening for common variable immunodeficiency (CVID) and hyper-IgM syndromes
Assessing B-cell subset reconstitution after stem cell or bone marrow transplant
Assessing response to B-cell-depleting immunotherapy
Identifying defects in transmembrane activator and calcium modulator and cyclophilin ligand (CAML) interactor (TACI) and B-cell-activating factor receptor (BAFF-R) in patients presenting with clinical symptoms and other laboratory features consistent with CVID
Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| TBBS | QN Lymphocyte Subsets: T, B, and NK | Yes | Yes |
| IABC | Immune Assessment B Cell Subsets, B | No | Yes |
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.
If immune assessment B-cell subsets test is abnormal, then confirmation will be performed at an additional charge.
When multiple specimen types are required to perform a panel of tests, the laboratory will perform the tests for which the appropriate specimen type was received and the laboratory will cancel those for which the appropriate specimen was not received. Please be advised that this may change the degree of interpretation received with the report. If only the refrigerate EDTA sample is received, this test will be canceled and converted to RBCS / Relative B-Cell Subset Analysis Percentage which provides the relative B-cell subset values without quantitation.
