| Abstract: | The efficiency of detection of blood in stains on material evidence by spectrofluorometry and fluorescent hemotest developed at Bureau for Forensic Medical Expert Evaluations of the Leningrad region and by traditional methods used in Russia and abroad is compared. The proposed methods are 1000 times more effective than the methods routinely used in Russia; moreover, they allow objective computer recording and processing. These methods are 50-70 times cheaper than the methods used in foreign countries and are virtually as sensitive. Fluorescent hemotest persuasively proves the presence of blood in stains on material evidence under laboratory conditions, at the site of accident, and even under field conditions (express analysis). |
