Test ID: IABCS    
B-Cell Phenotyping Profile for Immunodeficiency and Immune Competence Assessment, Blood

‹ Back to Pediatric index

NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.

Yes

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 IDReporting NameAvailable SeparatelyAlways Performed
TBBST- and B-Cell QN by Flow CytometryYesNo
IABCImmune Assessment B Cell Subsets, BNoYes

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 IDReporting NameAvailable SeparatelyAlways Performed
CVIDCVID Confirmation Flow PanelYesNo

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 test is abnormal, then common variable immunodeficiency (CVID) confirmation flow panel 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.
