title: Albumin autoagglutinating phenomenon as a factor contributing to false positive reactions when typing with rapid slide-test reagents.
abstract: A case of albumin autoagglutination has illustrated the point that this phenomenon may be a further source of false positive reactions when typing with rapid slide-test reagents. As agglutination only occurred with the bovine albumin solution and slide-test reagents from a single manufacturer, it is evident that control tests must be performed not merely with a high protein solution duplicating the formulation of the slide-test reagent itself, but with one from the same commercial source as the reagent.
