Types of Testing

Pre-Employment TestingThis is used as an indicator of candidate suitability, it forms an essential part of a company’s recruitment process, and helps maintain the safety of the firm’s current workforce.

Random TestingWith knowledge that a test could be conducted with anyone at any time, random testing is the most effective deterrent of drug or alcohol misuse among employees. It ensures integrity of staff across all levels and can be conducted with employees at any level from temporary staff to directors.

With-Cause TestingThis is conducted when there is suspected drug or alcohol abuse in the workplace, whether allegations are made, suspicion arises, if drugs and alcohol have been found in work or following an accident.

Post-Incident TestingPost-Incident testing occurs after an accident or incident in work to determine if drugs or alcohol may have contributed to the cause.

Abstinence TestingThe process of this testing is conducted in circumstances where an employee, having tested positive for a previous drug or alcohol test is monitored to ensure they remain abstinent from drug or alcohol misuse.
