Like many other immunological tests, this method works by the antigen-antibody reaction. This allows scientists to extract multiple sets of DNA from the same sample. 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. Immunochromatography is a method to test for diseases by dropping a small sample onto a prepared test strip. The dependent variable was death due to COVID-19, and .

This means if someone is being questioned by a police officer and he or she happens to pick up a newspaper off a table, the officer can take the paper and obtain DNA simply from where the paper was touched by the suspect. At test line, analyte-labeled antibody complex is captured by another antibody which is primary to the analyte. At conjugate pad, target analyte is captured by the immobilized labeled antibody and results in the formation of analyte-labeled antibody complex. Like DNA, fingerprints found at a crime scene can be matched to a suspect by comparing them. Specifically, immunochromatographic methods are combined with Gas Chromatography (GC) and Mass Spectrometry (MS) techniques to detect traces of methamphetamine and amphetamine. This is called physical fit and is a well-recognized method of determining that two pieces are from the same source.
