Results on forensic application of the C3 system.

The results of the application of the C3 system to 155 cases of disputed paternity are presented. In this preselected material (none of the 234 accused men could be excluded by any of the usual markers of red blood cells and serum) 23 men were excluded. Of these 23 exclusions, 17 could be examined in the HLA-system and were confirmed by this system. In 211 mother-child pairs no theoretically impossible combinations were observed.
