Common Variable Immunodeficiency Confirmation Flow Panel
NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.
Screening for common variable immunodeficiency (CVID)
Identifying defects in TACI and BAFF-R in patients presenting with clinical symptoms and other laboratory features consistent with CVID
Evaluating B cell immune competence by assessing expression of BAFF-R and TACI proteins
Useful for assessing BAFF-R and TACI protein expression and frequency of B cells bearing these receptors. TNFRSF13C (BAFF-R) and TNFRSF13B (TACI) gene mutations have been described in a small subset of patients with humoral immunodeficiencies classified as CVID. The majority of TNFRSF13B mutations preserve TACI protein expression and require genetic testing to identify pathogenic or potentially pathogenic mutations/variants.
