Toxicology test, any of a group of laboratory analyses that are used to determine the presence of poisons and other potentially toxic agents in blood, urine, or other bodily substances. Most commonly, biomarkers of exposures to stable compounds, such as metals, comprise measurements of the metal concentrations in appropriate samples, such as blood, serum or urine. It studies the detection and treatment of poisons, as well as the effects these chemicals have on the body. The invention of atomic absorption spectrophotometer by Alan Wash for the detection and analysis of trace metal elements has helped in the detection of poisons like cadmium and arsenic. They were often used as a ‘silent killer’ because some poisons leave few or no external traces, and their side effects – such as stomach cramps, vomiting, diarrhea or headaches – appear as regular symptoms for a host of other illnesses. The deposited drug is much stable and can be detected after a longer period of time as compared with other biological samples, e.g., saliva, blood, and urine. The discripline requires high level skills in analytical techniques with a solid knowledge of pharmacology and pharmacokinetics.
