Toxicokinetics (often abbreviated as 'TK') is the description of both what rate a chemical will enter the body and what occurs to excrete and metabolize the compound once it is in the body.

A toxicology screen is a test that determines the approximate amount and type of legal or illegal drugs that youâve taken. It may be used to screen for drug abuse, to monitor a substance abuse problem, or to evaluate drug intoxication or overdose. Toxicology screening can be done fairly quickly. The test is most often done using a urine or blood sample. In some cases, a sample of saliva or hair may be used. The results can show the presence of one specific drug or a variety of drugs at once.
