Toxicology: Oral Fluid Drug Testing

Posted on by Lolita Tsanaclis

The analysis of drugs of abuse in oral fluid is becoming more widely used and accepted across a number of testing disciplines, particularly because it is so simple to collect in comparison to urine. Oral fluid testing is now practiced in a variety of settings such as the workplace, drug-treatment centres, health assessments, and in the legal arena.

How to choose the best hair sample collector

Posted on by Chris Bell

The degree of training varies tremendously from company to company yet it is this part of the drug & alcohol testing process that is most commonly the weakest link in the ‘chain of custody’ process and therefore the most liable to challenges if not performed correctly!

Not all sample collectors are the same!

When you are having someone come into your organisation to collect a hair sample it is very important that they know what they are doing and disrupt your normal activities as little as possible.

Workplace drug testing policy

Posted on by Lolita Tsanaclis

In the Workplace, drug testing has many benefits; it can have a deterrent effect on existing employees and can be used to screen new employees.

Random drug tests for existing employees

The main use of drug testing in the workplace is to be confident that people are fit to perform specific tasks and ensure that no drugs are present in the person’s system that may impair performance or put others at risk. These tests are usually performed randomly. Whilst these tests do not accurately reflect or predict fitness to work, they do detect recent drug use when the test is positive.

Urine test is the most commonly used sample for illicit drugs. It detects the use of drugs within the last few days and as such is evidence of recent use; but a positive test does not necessarily means that the individual’s performance was impaired at the time of the test. And abstention from use for 3 days will often produce a negative test result.

The use of saliva (oral fluid) is ideal in such cases, when drugs are present in oral fluid samples, they actually reflect the use of drugs in the last 24 hours and so are very relevant in assessing impairment.

Pre-employment drug tests for job applicants

For some industries it is important to have the assurance that a job applicant is not a regular user of drugs.

In these cases testing a 3-centimetre head hair sample covering a period of three months is ideal because the candidate will have to abstain from drugs for 3 months for the test to be negative.

Most industries, however, still require a negative urine drug screen test as a condition for employment. This can only provide a 3 to 5 day window of detection at maximum and if the candidate is pre-warned of the test, the candidate can abstain before the test, making the test useless.

Sometimes organisations choose urine tests because it is perceived that a hair test is expensive. However, this perception is inaccurate, for a sample of hair covering a period of approximately three months is equivalent to 20 urine tests in the length of coverage it provides.

Moreover, if the result of the test is important to the employer, there are clear advantages to using a test that will give clear results of drug use over an extended period rather than a test that will not detect drug use if the candidate abstains for a few days before the test.

The use of drug testing in the Workplace requires a clear, written policy that is discussed and agreed with all employees before testing starts. One of the main questions you will face is “what will you do when people test positive?” This process not only needs to be written up in your company policies and procedures, but also discussed in terms of succession planning if a person was to leave their role as a result.

Which sample to use in drug testing?

Posted on by Lolita Tsanaclis

Nowadays the use of the three biological samples, urine, saliva and hair, is widely accepted for the detection and monitoring of drug use. They are complementary and each sample type has different advantages depending on the purpose of the test. There is not a best sample for drug analysis, just the ideal sample for a particular purpose.

Drug and Alcohol screening in the workplace is like 'a gate'.

Posted on by John Wicks

You may like to think about drug and alcohol screening in the workplace in terms of a ‘gate’.

When people enter the workplace, you want to make sure they are fit for the job. This is especially true when people have to operate heavy machinery. As such, a drug (including alcohol) test on the morning before they start work acts like a ‘gate’ - if you pass, you enter. If not, you may simply be sent home and you can return the next day to ‘try again’.
