The differentiation of an adult's bloodstain from that of a child using an indirect fluorescent antibody technique.
A procedure is described for the detection of specific antimicrobial antibodies in bloodstains. The technique is described and the relationship between antibody concentration and the age of the doner is reported. It is shown that, provided foetal blood can be excluded, an unknown bloodstain may be identified as that of a person over 15 years with a high degree of confidence.
