Results of blinded sample Immuno-SRM analysis conducted by alternate laboratory. Complete process replication included DBS card punching, extraction, digestion, enrichment and MS analysis. Normal Controls (n = 25) and patients (n = 11) are compared against the diagnostic cutoff established by SCRI. Signature peptide values for WASP 274 (A) and CD42 128 (B), BTK 407 (D), DOCK8 1272 (E), and ADA 93 (F) are shown in normals and PIDD patients. Comparative diagnosis shows agreement in patient identification (C).
