ABO Blood Type Identification and Forensic Science (1900-1960) The use of blood in forensic analysis is a method for identifying individuals suspected of committing some kinds of crimes. The D (Rh0) antigen is the strongest antigen, leading to immunization if introduced to the other person. .recentcomments a{display:inline !important;padding:0 !important;margin:0 !important;} In the case of an incorrect reading of the results or interpretation will give false-positive or false-negative results. Your antigen makeup is the key factor in determining your blood type. Former is easier to perform and the latter is more sensitive. Can be used in emergency and blood camps for preliminary grouping. Rh system is second in importance to the ABO system. Red cells from the specimen are reacted with reagent antisera (anti-A and anti-B). However, these advantages are somewhat offset by the large size and high cost of the instruments. The A, B, and O antigens are present in most human body cells, including white blood cells and platelets. This can be done on whole blood or even on clotted blood. Grouping is at its very best when it bears directly toward a timely teaching goal, and for many teaching situations, group learning is more efficient. It is defined as using a known source of antibodies to detect the antigens on the red blood cells. Activate your 30 day free trialto unlock unlimited reading.
