RSID-Semen
Definition
Rapid Stain Identification of Semen: an immunochromatographic lateral-flow strip from Independent Forensics that detects semenogelin I and II with sensitivity to approximately 1 in 10,000-100,000 dilution of semen. Remains positive on aged and degraded samples independently of PSA results.
