Since its inception in 1993, results from seven mailings of the joint American Association of Blood Banks/College of American Pathologists parentage testing survey program, PI, have been analyzed. Results were reported in six red cell antigens (RCA), 14 serum proteins (SP) and 11 red cell enzymes (RCE) genetic systems. The total number of laboratories reporting results, the number of results reported and the number of non-consensus answers are listed in Table 1.
