ABSTRACT

A simple method using a vacuum diffusion technique for concentrating limited quantity bloodstains and seminal fluid stains is outlined. Bloodstained materials washed under various conditions were tested using the Hemochromogen test and the Anti-Human Globulin test before and after concentration. Seminal fluid stains were typed in the Glo I and PGM1 systems before and after concentration. This concentration technique can be applied to casework situations.

RÉSUMÉ

L'article décrit une méthode simple de concentrer une quantité limitée de taches de sang ou de sperme au moyen d'une technique de diffusion à vide. Diverses matières tachées de sang ont été lavées de différentes façons et testées au moyen de l'épreuve à hémochromogène et du test à l'anti-globuline humaine, avant et après concentration. Les taches de sperme ont été classifiées dans les systèmes Glo I et PGM1 avant et après la concentration. Cette technique de concentration peut servir pour l'étude de cas pratiques.
