Ante- and post-mortem bloodstains prepared from the blood of volunteers and corpses were analysed for ATP and its related compounds by reversed-phase high-performance liquid chromatography (HPLC). The results showed that (1) ATP was present in a large amount in antemortem bloodstains but not in postmortem stains, (2) AMP, adenosine, inosine, hypoxanthine, xanthine and uracil either were not detected or were detected in smaller amounts in antemortem than in postmortem bloodstains, and (3) ADP was present in both ante- and post-mortem bloodstains. These differences suggest that quantitation of these compounds may be useful in identifying whether bloodstains are ante- or post-mortem.
Identification of the gender of an individual(s) from whom a bloodstain is derived represents important evidence in medicolegal cases. The efficacy of fluorescence in situ hybridization (FISH) using chromosome X and Y centromeric probes was tested to determine its ability to identify correctly the gender of extracted dried bloodstains. In this preliminary study, FISH correctly identified the gender of 2-week-old dried bloodstains in prepared mixtures of male-to-female blood as low as 1%. The technique is accurate, rapid, sensitive, easily performed and readily available. This application of FISH as a forensic laboratory technique holds great promise.
