  • 1.Why use random drug tests?
     

    Random, unannounced drug tests are a very effective deterrent. They are also an excellent complement to training and information about the company’s attitude towards and policy on drugs. Random drug testing keeps the drug policy fresh in people’s minds and helps to ensure assistance to those employees who have fallen into addiction.

  • 2.Why A- and B- samples?
     

    We always use A1, A2 and B samples for extra security. The drug test is done on the A samples. If the first test and the confirmation test both turn out positive for something you know you haven’t taken, you can always request an analysis of the B sample. The B sample is for the test subject’s security. B samples are stored in a freezer according to the lab’s routines (usually for one year) in case the A sample comes out positive.

  • 3.Is it possible to cheat on a drug test?
     

    If you really want to, you can cheat on any drug test. However, it is difficult to do, and skilled and experienced testers make it even more difficult. But it does happen, and the easiest tests to cheat on are scheduled drug tests. With random drug testing you never know when you will be called, so the only way to cheat on a random, unannounced drug test is to be prepared for one every single day.

  • 4.Do you see anything besides drugs when you analyse the test?
     

    No. The laboratory sees nothing but the specific drugs we analyse for. There is NO risk that we will see if the person is pregnant or has certain genes or diseases, nor are we interested in that.

  • 5.What type of drug test method is preferable?
     

    NDP have chosen to remain neutral on the issue, but we have tried most methods. So far, the National Board of Health and Welfare and all accredited Swedish laboratories (that deal with workplace drug testing) have defined urine as the “gold” standard for drug testing. This is also a cost issue – urine tests are much less expensive than, say, saliva or hair analysis. Another consideration is how long it takes to get the results. These days we also have a breath analysis method. A breathalyser test is easy to take and can be used in any environment. We can offer all of these tests, and we discuss with the client to arrive at the best solution for their situation and wishes, based on our experience.

  • 6.How many of our employees should we randomly test per year?
     

    For the greatest effect, a reasonable number is about 25% of the workforce, but this is something that we discuss and decide on jointly. Some companies want to test everyone, others fewer. Most of our customers test 25% and some have specific rules for how many to test.

  • 7.How do you test for alcohol?
     

    We use the same advanced fuel cell breathalysers that the police use. The difference is that we can document our results, as we always have printers connected to the devices. We calibrate the breathalysers frequently to be sure our equipment is accurate.

  • 8.How do you choose a random sample?
     

    We work only with non-name-related data (such as employee numbers). Shortly before a test, we receive employee numbers from the workplace and randomly select the agreed number of test subjects. Since NDP make this selection, there is no reason for anyone to suspect that someone at the company is “singling people out”. We are completely neutral and don’t know who the random number generator will select.

  • 9.How many positive drug tests do you find?
     

    The results are fairly constant from year to year: somewhere between 1 and 2% of confirmed positives annually.

  • 10.Do you use "rapid tests" for drug testing?
     

    No. We work only with the Karolinska Pharmacological Laboratory. Rapid tests for urine are not sufficiently reliable for workplace drug testing.

  • 11.Are medicines a problem?
     

    Medicines are drugs, and prescribed correctly to the right person for the right use, there is no problem. It is only when the drug is not used appropriately that it can become a problem. Certain narcotic drugs are highly addictive and can become a severe, hard-to-treat problem for the individual. Usually this is combined with abuse of other substances, for example alcohol and controlled medicines. Overuse of just one controlled pharmaceutical can lead to intoxication, making the person a potential hazard in the workplace. NDP always discuss with the client what type of drug testing panel they think is appropriate and what drugs should be included, depending on company policies and the type of activities.
