Choosing a sample to analyse
The following samples are most commonly used to screen for drugs of abuse in the workplace:
- Urine: Around 75% of the organisations that SYNLAB works with utilise urine testing as their sample of choice. Within the workplace urine is considered to be the gold standard across the industry as it’s highly reliable and easy to collect and analyse. Urine is also the easiest sample medium used for cannabis detection – the most commonly abused substance within the UK.
- Saliva: Particularly useful in situations where toilet facilities are not readily available, saliva testing is an unobtrusive method, commonly used within the workplace to screen for drugs of abuse. With a narrower window of detection, saliva is used to look for use within the past day or less.
- Hair: Collecting a hair sample to screen for drugs of abuse is not commonly used as a front line method within the workplace, but is more commonplace in the medico-legal sector such as child custody cases. In the workplace if an employee has come forward and says they have a drug or alcohol problem, hair testing can be used during the rehabilitation process for a longer term assessment as it has the largest detection window, and can look at historic drug abuse over a number of months, as well as being used as as tool to prove abstinence.
