Cat. #140 Blood Typing
For 10 Groups. In human blood, there are two major antigens and antibodies designated as A or B and anti-A or anti-B. Blood type (A, B, AB, or O) can be determined using an agglutination assay where roughly equal concentrations of sample antigen and previously isolated antibodies are mixed and then moni - tored for precipitation. This test is often used to ensure safe blood transfusions. However, it can also be used in the field of forensics. Agglutination assays can confirm that collected evidence is human blood before more time intensive tests are performed. In addition, blood typing can screen potential suspects by blood group.
