Test ID: IABCS
B-Cell Phenotyping Profile for Immunodeficiency and Immune Competence Assessment, Blood
Secondary ID 
A test code used for billing and in test definitions created prior to November 2011
88800
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 TACI and 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 | Secondary ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|---|
| TBBS | 9336 | T- and B-Cell QN by Flow Cytometry | Yes | Yes |
| IABC | 87994 | Immune Assessment B Cell Subsets, B | No | Yes |
Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)
| Test ID | Secondary ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|---|
| CVID | 87993 | CVID Confirmation Flow Panel | Yes | No |
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
If immune assessment B-cell subsets is abnormal, CVID/87993 Common Variable Immunodeficiency Confirmation Flow Panel will be performed at an additional charge.
