ABO(H) isoantigens in bladder tumors: a new technique of quantitative analysis

The specific red cell adherence test appears promising to predict which superficial bladder tumor(s) ultimately will become invasive. However, presently the test cannot be quantitated and, thus, cannot be standardized. We describe a technique for the quantitative analysis of ABO(H) isoantigens in bladder tumors, which should help to standardize the test for prospective clinical trials.
