Objectives While DNA profiling has become the principal technique for individualization of biological evidences, ABO blood grouping is still a useful test method in the initial stages of crime investigation. Objectives of the study were blood group determination using slide agglutination method, blood group determination from saliva using absorption inhibition method, and comparison of slide agglutination method with that of absorption inhibition method from saliva sample.

Materials and Methods A total of 60 subjects were taken randomly with their age ranging from 20 to 60 years. Sixty subjects were divided in to two groups, study group and control group. 5 to 10 mL of unstimulated saliva was collected from 60 patients and Wieners agglutination test was performed to detect the secretor status of blood using absorption inhibition method and compared with that of slide agglutination method

Results Out of 60 subjects, 52 subjects showed secretors of antigen in saliva with percentage value of 86.66% and eight subjects were nonsecretors (13.33%). Slightly higher percentage of secretor status was seen in males 84.6 and 88.2% in females.

Conclusion Evaluation of secretor status of blood group antigen from saliva using absorption inhibition method can be useful method in identification of medicolegal cases.
