Forensic serologists conduct examinations of suspected biological evidence in order to identify the material positively. 1: establish that it is of human origin. 3. try to associate it with particular individuals as possible source. 2 types of test: presumptive test : good negative, confirmatory test : good positive presumptive test inexpensive, simple. 2: safe, easy to perform, very sensitive, use of very small amount of material, no adverse effect on the downstream dna tests (presumptive) test of blood. A positive result from the kastle-meyer(phenolphthalein test) color test is highly indicative of blood a deep pink color. Alternatively, the luminol test(3-amino-phathalhydrazide) is used to search out trace amounts of blood located at crime scenes (produces light (luminescence) in a darkened area)
