In 1901, Karl Landsteiner announced one of the most significant discoveries of the 20th century, the typing of blood. This finding 29 years later earned him a Nobel Prize. Out of Landsteiner's work came the classification system that we call the A-B-O system. By 1937, the Rh factor in blood had been demonstrated, and shortly thereafter, numerous blood factors were discovered. More than 100 different blood factors have been identified. However, the the A-B-O system and Rh factor continue to be the most important for properly matching blood donors and recipients for transfusions, as well as in forensic science for linking or excluding individuals to crime scenes. The advent of DNA technology has dramatically altered the approach of forensic scientists toward individualization of bloodstains and other biological evidence. But with the expensive nature of DNA testing, simple blood typing is an inexpensive way to exclude suspects. Forensic serology is the detection, identification, classification, and study of various bodily fluids such as blood and their relationship to a crime scene. Serology involves a broad scope of laboratory tests that use specific antigen and serum antibody reactions. An antibody reacts or agglutinates only with its specific antigen. This project will allow students to discover their own blood type using antisera. Students will be able to either perform their test at home or visit our School Based Health Clinic to get assistance from a Nurse Practitioner.
