High-throughput DNA typing could facilitate support for patients undergoing long-term transfusion who are at high risk of alloantibody production, such as patients with sickle cell disease, thalassemia, or autoimmune hemolytic anemia.
Further laboratory results (direct antiglobulin test and bilirubin) were assessed and reported for five babies whose maternal alloantibody titre by IAT tube was less than 16, but equal to 16 by CAT.
Immunotoxicity testing showed that there was no treatment-induced alloantibody formation or induction of autoimmunity.
Maternal anti-K is the second most common alloantibody (anti-D is the first) and accounts for 10%45% of all patients with antibody-mediated severe hemolytic anemia (2).
21(p34)] Consequently, the CAP J-Survey data were analyzed based on whether the challenge sample contained an alloantibody (alloimmunized) or not (nonalloimmunized).

These false-negative antibody screening results pose a high risk for patients; (13) it has been well documented that the failure to detect weakly reactive red cell alloantibody can lead to a rapid anamnestic production of antibody and delayed hemolytic transfusion reactions.
