[A comparison of the Bluestar and luminol effectiveness in bloodstain detection].

The objective of the present study was to compare the effectiveness of two chemical agents--Bluestar and luminol--in detection of bloodstains. The experiments were performed to test for bloodstain detection sensitivity, chemical stability and to investigate the effect of both reagents on DNA typing. During this study, the authors prepared serial dilutions (1:2 to 1:10 000 000) of fresh blood, as well as dilutions of 25-year old blood on Whatman 3MM blotting paper.
