Abstract

Forensic Biology is the study of biological evidences which found at the crime scene & their study and examination for the purpose of justice. And in regards with the same of serological evidences, is known to be Forensic Serology. Blood is biological evidence which is a common type of evidence found at most of the crime scenes. Blood is a bodily fluid which consists of cellular & non-cellular components. In this review article we will discuss about the two types of preliminary tests for blood detection which may found at the possible crime scenes, here we will analyze through the TMB (i.e., Tetra Methyl Benzidine) and Phenolphthalein Assay (also known as Kastle Mayer’s test) and differentiate between those & will come to the conclusion which is the best method or test for the preliminary blood stain detection amongst the both while conducting the assays for blood samples.
