Importance of Chemical Tests for Detection of Seminal Stains in Medico-Legal Investigations

Stains Other Than Blood-Stains as Medico-Legal Evidence

On one point an important difference of opinion may exist between medico-legal workers: should a positive chemical test, in the absence of finding spermatozoa under the microscope, be accepted a& evidence of semen ? Some are in favour of doing so (Bagchi, 1937), others against (Owens, 1935; Thomas, 1937; Kamath, 1938; Glaister, 1938; McNally, 1939; Modi, 1940; Rhodes, 1940) and yet others appea...

Examination of Seminal Stains in Medico-Legal Cases

Experiments on the Stability of Seminal Stains from a Medico-Legal Standpoint

Significance of Florence Test for Seminal Stains *Being a paper read (in modified form) at the medical section of the Indian Science Congress held at Hyderabad on the 2nd to 8th January, 1937.

The choline periodide, or Florence test, for seminal stains has been proved to be of immense value in medico-legal work and adopted as a routine test in all medico-legal laboratories. In this laboratory the seminal stains are always examined for the micro-crystals of choline periodide as well as the spermatozoa and the result is expressed in terms of spermatozoa, viz, positive or negative accor...

The use of Polilight in the detection of seminal fluid, saliva, and bloodstains and comparison with conventional chemical-based screening tests. J Forensic Sci 2006;51(2):361-70.

Biological stains can be difficult to detect at crime scenes or on items recovered from crime scenes. The use of a versatile light source may assist in their detection. The ability of Polilight to locate potential semen, saliva, and blood stains on a range of substrates and at different dilutions was tested. We also tested the use of Polilight in comparison with conventional chemical-based pres...
