| Abstract: | Gm- 1-, 2-, and Inv 1-factors can be demonstrated in semen and saliva. For the examination of traces it is necessary to verify the suitable dilutions for the different charges of antisera and to test the eluates of the samples if they have a sufficient concentration. We observed some incorrect negative results in seminal and saliva stains which were apparently caused by insufficient material. The demonstration was independent of the secretor type. Haptoglobin could not be determined in semen and saliva. |
