Many of the common techniques used to identify particular fluids have been around for decades. Some of these techniques have changed very little such as the luminol [2] and crystal tests [3] for blood and the microscopic identification of spermatozoa to confirm the presence of semen [4]. Others such as the presumptive tests to identify heme in blood, acid phosphatase in semen, and amylase in saliva have evolved over the years due to advances in technology, better understanding of the nature of the fluids, or even to prevent exposure to hazardous chemicals. A few new methods have been discovered, and the majority of these involve the detection of specific messenger ribonucleic acid (mRNA) markers to identify different body fluids [5], [6] and [7]. Over time they will possibly be expanded upon and become more accepted by the forensic community.
