Forensic medicine can help infer the cause of death of the deceased through anatomical examination, tissue biopsy examination, and poison examination. For some deceased patients, the drugs or drug residues in their bodies can be tested to infer the types of drugs they have taken, and then whether the disease is the cause of death. The use of drug & metabolite standards can be used for rapid qualitative testing through the instrument and shorten the identification time. I would like to know how to choose the right standards.
