Advanced technologies are making it possible to test drugs or blood samples rapidly. According to a recent report, four leading screening companies – Alere, Synergy Health, LGC Group and BioClinics – said that workplace drug testing has increased significantly in the UK.
Two companies saw rises of 100% and 470% in number of tests carried out annually over a period of four years. While traditional requests are for amphetamines, cocaine, cannabis, opiates, more requests are now seen for ketamine, steroids and new psychoactive substances. An important factor driving the growth for drug testing in offices is greater employer awareness about drug use among workers.
In September 2014, Quest Diagnostics reported that the percentage of positive drug tests among American workers increased for the first time in more than a decade, spurred by the rise in the use of marijuana and amphetamines. The report was based on an analysis of 8.5 million urine, oral fluid and hair workplace drug test results. Compared to 3.5 percent in 2012, the Drug Testing Index (DTI) showed that the positivity rate for 7.6 million urine drug tests in the combined US workforce increased to 3.7 percent in 2013.
According to the DTI analysis of urine drug tests, marijuana continues to be the most commonly detected illicit drug. Marijuana positivity in the combined US workforce increased 6.2 percent, to 1.7 percent in 2013 compared to 1.6 percent in 2012.
The development of quality diagnostics for the detection of drugs-of-abuse and measurement of therapeutic drug levels by leading companies like Siemens Healthcare Diagnostics have made drug testing fast, accurate and efficient.
