Test Comments:
Help
The neutrophil alloantigens HNA-1a, HNA-1b, HNA-1c, HNA-3a, and HNA-4a have all been reported to cause neonatal alloimmune neutropenia (NAN). Antibodies against HNA-1a, -1b, and HNA-3a have all been implicated in cases of TRALI, with HNA-3a antibodies being the most frequent cause of fatal TRALI reactions. Population studies suggest the HNA-1c …
