For automated data analysis to be accepted in court, it has to be based on models that are reproducible, explainable, and testable. Test line contains pre-immobilized antigen (same analyte to be detected) which binds specifically to label conjugate. Like DNA, fingerprints found at a crime scene can be matched to a suspect by comparing them. The test depends on the type of sample collected from the crime scene. American Academy of Forensic Sciences | American Academy of Forensic . Forensic serology is the detection, identification, classification, and study of various bodily fluids such as blood, semen, saliva, and urine, and their relationship to a crime scene.A forensic serologist may also be involved in DNA analysis and bloodstain pattern analysis. These products are widely used in the rapid diagnosis and effective treatment monitoring of critical and severe diseases, chronic disease management, maternal and children healthcare, blood glucose monitoring, drug detection, alcohol testing, forensic expertise and other fields. The set-up of this test is on a chromatographic paper and the lateral flow of the sample is by capillary action.
