Recent drug test rates show that positive workforce tests from 2021 climbed to the highest level since 2001, according to a new analysis released by Quest Diagnostics, a leading provider of preemployment and post-accident drug and alcohol testing.
Quest Diagnostics’ study was based on a total of more than 11 million deidentified urine, hair, and oral fluid drug test results from its testing index collected between January and December 2021. In 2021, the rate of positive drug test results among America’s workforce was found to be 4.6%, up from 4.4% in 2020. 2021’s positive test average is Quest Diagnostics’ highest recorded since 2001 and is up more than 30% from the all-time low of 3.5%, recorded 10 years ago.
