Evaluation of an AutoAnalyzer method for quantitating anti-A and anti-B haemagglutinins in factor VIII preparations

The continuous flow principle employed in the Technicon AutoAnalyzer has been adapted for the assay of anti-A and anti-B. The method has an acceptable degree of reproducibility and has been used, principally, for the quantitation of anti-A and anti-B in factor VIII concentrates of intermediate activity. It is, however, a method that can be applied to the assay of these antibodies in serum samples.
