Uhlenhuth test

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.^[1] The test was further refined for forensic use by the Swiss chemist Maurice Müller in the 1960s.^[2][3]
