A facility can offer a rapid class screen while relying on a separate process for a quantitative toxicology result. Otani and colleagues asked Japanese emergency departments about both kinds of testing.
Of 546 designated teaching institutions invited, 246 responded. The study reported which qualitative drug screening kits facilities used and separately asked whether specified toxicants could always be analyzed immediately. Only 2.4% of responding facilities reported that benzodiazepine analytical results were always immediately available in that part of the survey.
Check whether the result is a qualitative class screen, a targeted identification or a quantitative concentration. Confirm the specimen type and whether the test was completed in-house or sent out. The survey describes responding hospitals in the study period. It cannot establish what a particular laboratory offered on the date of an individual case.
