Editing Drug test (section)

===Diagnostic screening===
In the case of life-threatening symptoms, unconsciousness, or bizarre behavior in an emergency situation, screening for common drugs and toxins may help find the cause, called a ''toxicology test'' or ''tox screen'' to denote the broader area of possible substances beyond just self-administered drugs. These tests can also be done post-mortem during an autopsy in cases where a death was not expected. The test is usually done within 96 hours (4 days) after the desire for the test is realized. Both a urine sample and a blood sample may be tested.<ref name=webmd>[http://firstaid.webmd.com/toxicology-tests WebMD --> Toxicology Tests] {{Webarchive|url=https://web.archive.org/web/20120115101950/http://firstaid.webmd.com/toxicology-tests |date=January 15, 2012 }} </ref> A blood sample is routinely used to detect [[ethanol]]/[[methanol]] and [[Acetylsalicylic acid|ASA]]/[[paracetamol]] intoxication. Various panels are used for screening urine samples for common substances, e.g. ''triage 8'' that detects [[amphetamines]], [[benzodiazepine]]s, [[cocaine]], [[methadone]], [[opiates]], cannabis, [[barbiturates]] and [[tricyclic antidepressants]].<ref>{{Cite web|url=http://www.surrey.ac.uk/MDA/Pages/GuildfordEvaluations/PreviousReports/Reports/Drugs%20of%20abuse%20report.htm|archiveurl=https://web.archive.org/web/20110811080853/http://www.surrey.ac.uk/MDA/Pages/GuildfordEvaluations/PreviousReports/Reports/Drugs%20of%20abuse%20report.htm

Similar screenings may be used to evaluate the possible use of [[date rape drug]]s. This is usually done on a urine sample.<ref name=webmd/>
