Drug & Alcohol Testing

Workplace Testing

YCDI D&A Testing Services provides drug and alcohol testing for various safety-critical workplace industries. To ensure reliable results, our drug and alcohol screening procedure is coherent with strict chain of procedures to ensure sample integrity and traceability from point of collection to result reporting.

The 7 panel saliva drug test just requires the person being tested to put the test under their tongue for ~3 mins. Not only is this the easiest and most accurate drug test to use. It is also, as best we know, the only oral drug test that is specifically produced for the UK market and covers the 7 main street drugs found in the UK. The following substances can be detected with the 7 panel saliva drug test: COC/AMP/OPI/THC/BZO/MTD/MET/ALC

Below outlines the process of testing for those in the safety-critical industries.

Throughout sample collection, sample integrity is maintained following strict chain of procedure criteria. Unique identification numbers are assigned to employees to ensure employee names or department information is not known, the end report, will all relevant details, will be sent to the companies designated colleague.

5. Sample Analysis

All analysis is completed on site and the results report will be issued 24-48 Hours post test.

Upon analysis of employee samples, required actions will differ depending on the result:

How do drugs get into the saliva?

The salivary glands are only separated from the surrounding blood vessels by a thin skin. Active ingredients such as drugs and medicines penetrate this membrane and pass from the blood into the saliva. For this reason, test results in blood and saliva are very similar. This is why the saliva 7 panel drug test is very effective.

What are the differences between the 7 drug saliva test and urine tests?

The saliva test is, in contrast to the blood test, non-invasive and therefore easy to perform everywhere. The results are almost identical to the results of blood analyses as the transition from blood to saliva is very successful. Although THC enters the saliva to a lesser extent, as THC accumulates in the oral cavity during smoking, so it also provides reliable evidence.

What advantages does the 7 drug saliva test offer in contrast to a urine test?

The saliva drug tests are a very effective, efficient and reliable method of detecting drugs due to their high level of agreement with the confirmation analysis in the blood. In contrast to urine tests, a manipulation of saliva samples is almost impossible because the test can be monitored at any time without harming the privacy of the test person.

What are the guidelines for testing in the Workplace?

Our testing fully complies with the European Workplace Drug Testing Society Guidelines (EWDTS) which can be found here:
