Many markers of clinical values for liver disease, sexually transmitted diseases, cardiac markers as well as markers for mens and womens reproductive health can be rapidly detected by immunochromatographic assay. In cases where those samples are highly degraded, however, they often turn to the more powerful DNA sequencer, which allows them to analyze old bones or teeth to determine the specific ordering of a persons DNA nucleobases, and generate a read or a unique DNA pattern that can help identify that person as a possible suspect or criminal. In this article, we shall discuss everything about forensic serology including its history, how it works, what samples it uses, and how it helps to solve criminal investigation challenges. Although this forensic technology is not considered the most reliable, it is definitely one of the most interesting available to forensic pathologists, forensic anthropologists, and forensic scientists. In forensics, immunochromatography tests detect substances in subjects bodily fluids, such as drugs and medications. At test line, analyte-labeled antibody complex is captured by another antibody which is primary to the analyte. This can include blood, as well as saliva, semen and urine.
