Urine samples from 28 donors with known blood group and secretor status were concentrated by three different procedures, and ABO typing on the concentrated samples was successfully performed after 12 weeks of storage. The effects of storage with or without sodium azide on ABO typing and on the pH values at several different temperatures were also studied.
