Study ABO Blood Grouping of Forensically Important Saliva Samples through Assessment of Surface Materials-an Effective Parameter
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 12
Abstract
Detection of saliva stains encountered in forensic investigation is one of the primary objectives for forensic serologist as saliva may be an important source of DNA. Blood grouping can be done from the saliva if the person is secretor in status. Saliva is one of the vital fluids secreted in human by salivary glands, which may be deposited on the human skin through biting, sucking, licking, kissing, and possibly through other behaviors and often found in various types of crime scenes, such as hanging, sexual harassment, rape, homicide, suicide. Saliva stains may be found on any surface at the scene of crime as vital evidence. In study saliva stains were prepared on different fabric materials and metals in the laboratory as such the mimic of crime scene was created. Blood grouping examination was done for the piece of different fabric materials between the time intervals of 24 hours. The present study was undertaken to find out the maximum duration for which blood grouping is possible for respective blood group when the stains are obtained from different fabric materials and metals and also to determine the affection on blood grouping by different surfaces of fabric materials.
