Statistical Evaluations

Each year LabToxx and the Laboratory Krone make a statistical evaluation of their drug testing results in the context of MPA (Medical Psychological Assessment).

Between 2014 and 2019 the percentage of positive test results for amphetamine and its derivates, methadone and benzodiazepines in urine samples has not changed significantly. However, there is a noticeable increase in samples tested positive for cocaine in 2016 which was confirmed in 2017, 2018 and 2019.
When looking at the differentiation of amphetamine and its derivatives in urine, no significant changes can be observed within the relative proportions of amphetamine, methamphetamine, MDA and MDMA.
The hair samples analysed between 2014 and 2019 show neither for amphetamines nor for cannabinoids, cocaine, opiates, methadone and benzodiazepines clear trends.
In contrast to the urine test results, the differentiation of amphetamines in hair showed an increase in amphetamine, MDA and MDMA. However, the numbers for methamphetamine stayed the same in comparison to previous years.
Comparing urine samples to hair samples, the later showed a larger percentage of positive test results for amphetamine, cannabis/THC, cocaine/benzoylecgonine, opiates and methadone.
The same is true for ethyl glucuronide (marker for alcohol consumption). The percentage of positive test results in hair samples was significantly higher than it was in urine samples.

Only positive results confirmed using GC-MS, GC-MS/MS or LC-MS/MS are displayed above.

Further information on relevant topics

MPA Fitness to Drive

In most industrial countries if a driver loses his driving license as a result of drug or alcohol offense he has to prove abstinence for several months up to one year. The exact conditions of drug testing in urine or hair are different from country to country and depend on the individual situation.

Alcohol and Drug Tests

Here you will find information about the analytical techniques used for the detection of drugs, the cut-off values used and the chain of custody which is of particular importance in forensic toxicology.

Workplace Drug Testing

During the last few years workplace drug testing has been gaining rapidly importance in many countries. Human failure is often the origin of accidents at the workplace rather than technical defects. Consumption of alcohol, drugs and medications play offen a significant role.

Child Custody

In the context of adjudication of child custody the youth welfare service or court of justice can require a drug or alcohol test of one or both parents to objectively prove their allegations.
