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 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 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)

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 is abnormal, CVID confirmation flow panel will be performed at an additional charge.
