Evaluation of Salivary Secretory Status of ABO Blood Group Antigens using Hemagglutination Inhibition Method

Abstract: ABO blood grouping is still a helpful test procedure in the early phases of criminal investigations, even though DNA profiling has emerged as the primary tool for individualizing biological evidence. Because a person's blood type remains constant throughout their lives, blood is regarded as one of the most crucial materials for crime scenes and disaster scenes. Antigens are produced from the body in a variety of ways in addition to blood, including saliva, nasal secretions, tears, semen, urine, sweat, etc. 40 Samples were used in the investigation and hemagglutination inhibition test was performed to detect the secretor status of blood. From the present study the percentage breakdown for each group of secretors and non-secretors assuming that A group has 80% secretors and 20% non-secretors, B group has 73.3% secretors and 26.7% non- secretors, AB group has 100% non- secretors, and O group has 90% secretors and 10% non- secretors. According to the study, blood group O has a higher secretory rate (90%) than other blood groups.
