Test ID: BTKK    
Bruton Tyrosine Kinase (BTK) Genotype, Known Mutation, Blood

Useful For Suggests clinical disorders or settings where the test may be helpful

As a follow-up confirmatory genetic test for relatives of X-linked agammaglobulinemia (XLA) patients with a previously identified Bruton tyrosine kinase gene (BTK) variant, after abnormal Btk protein expression has been previously demonstrated (eg, BTK / Bruton Tyrosine Kinase [Btk], Protein Expression, Flow Cytometry, Blood)
