Uhlenhuth test

{{Short description|Test for source species of blood}}

The Uhlenhuth test, also referred to as the antigen–antibody precipitin test for species, is a test which can determine the species of a blood sample. It was invented by Paul Uhlenhuth in 1901, based on the discovery that the blood of different species had one or more characteristic proteins. The test represented a major breakthrough and came to have tremendous importance in forensic science in the 20th century.Michael Kurland, Irrefutable Evidence: A History of Forensic Science (p. 200), Dee, 2009, {{ISBN|9781461662396}} The test was further refined for forensic use by the Swiss chemist Maurice Müller in the 1960s.Keith Inman, Norah Rudin, Principles and Practice of Criminalistics: The Profession of Forensic Science (p. 32), CRC Press, 2000{{cite web|url=https://prezi.com/ghkb2srvkk6s/the-precipitin-test/|title=The Precipitin Test|website=prezi.com|language=en|access-date=2017-12-17}}
