Preferred test for confirming a diagnosis of X-linked agammaglobulinemia (XLA) in males with a history of recurrent sinopulmonary infections, profound hypogammaglobulinemia, and below 1% peripheral B cells
In females, this is the most useful test for identifying carriers of XLA.
By including protein and gene analysis, this test provides a comprehensive assessment and enables appropriate genotype-phenotype correlations.
