Detection of ketamine in drug screenings is a function of the specific test administered and the timeframe since ingestion. Standard drug tests often do not include assays for ketamine. When present, it can typically be detected for a limited period post-administration, dependent on factors such as dosage, individual metabolism, and the type of sample collected (urine, blood, or hair).
The necessity to identify ketamine stems from various clinical and legal contexts. Its use as an anesthetic and analgesic, its potential for abuse, and its presence in cases of drug-facilitated assault underscore the importance of reliable detection methods. Historically, specific testing for this substance has been less common, but increasing awareness of its diverse applications and potential harms has led to greater demand for its inclusion in drug screening panels.
