SERATEC® PSA Semiquant Test

The SERATEC® PSA Semiquant Test is a sophisticated forensic tool designed for the rapid and reliable identification of Prostate-Specific Antigen (PSA), a potent marker for human seminal fluid. While the PSA protein (also known as p30) was originally utilised for the clinical diagnosis of prostate cancer, it has become an indispensable instrument in forensic serology. It is particularly vital in cases where spermatozoa may be absent, such as in samples from vasectomised or azoospermic individuals, making it a critical component of any sexual assault investigation kit.

This test utilises high-affinity monoclonal antibodies to detect PSA with exceptional sensitivity. What sets the SERATEC® PSA Semiquant apart from standard qualitative tests is its ability to provide semi-quantitative data. By including a reference line on the cassette, investigators can estimate the concentration of PSA in a sample. This feature is crucial for assessing the age or dilution of a stain and helps forensic scientists determine the most viable areas for subsequent DNA extraction and profiling.

Engineered for both the rigours of the crime scene and the precision of the laboratory, this test is designed for robustness and ease of use. The immunochromatographic format ensures that results are available in just 10 minutes, allowing for real-time decision-making during evidence processing.

In the high-stakes environment of criminal justice, the SERATEC® PSA Semiquant offers the scientific validity required to withstand legal scrutiny. By confirming the presence of seminal fluid through a globally recognised marker, this test provides the objective evidence necessary to reconstruct events and identify perpetrators with confidence.
