A method of rapid Rh typing employing the capillary tube technique and papainized incomplete anti-D sera

The application of the capillary-papain technique to the rapid matching of blood for transfusion

“…The object of this paper is to describe the application of the capillary-papain technique for rapid Rh typing (Gilbey, 1961) to emergency cross-matching and to offer experimental evidence of its reliability in comparison with the indirect Coombs test and certain albumin techniques. EXPERIMENTAL The technique employed was essentially similar to that previously described for rapid Rh typing, the serum of the recipient being substituted for the anti-D typing serum.…”
