Hair analysis

Information on performing a hair analysis (scalp hair) as part of the abstinence control

(MPU, fitness to drive diagnostics)

Status: Dec. 2019

Dear client,

You have opted for a proof of abstinence with regard to alcohol or narcotics by means of a hair analysis. In order for this process to go smoothly, we need your name, your date of birth, your address and yours ID card / passport number capture. All data will be treated confidentially by us in accordance with the applicable data protection guidelines and medical confidentiality and will not be passed on to third parties. Please bring them in valid official identification document With. Expired or replacement documents (ID cards, public transport tickets, etc.) not accepted become.

I) What you should know before doing a hair analysis

Evidence of the consumption of alcohol or narcotics can be provided by examining hair. Proof that the hair is free from substances can therefore be used as evidence of abstinence (e.g. in the diagnosis of fitness to drive or for presentation to court). When interpreting the findings in the diagnosis of fitness to drive, an average growth of one centimeter per month is assumed for the scalp hair. This enables a retrospective assessment according to the examined hair length.

Hair is not substance-free immediately after the start of abstinence. In the growth phase (anagen phase), newly formed scalp hairs reach the surface of the scalp after about 9-14 days. For a proof of abstinence, this means that in the first month after the start of abstinence, a waiting time of approx. 2 weeks must be taken into account until "substance-free" hair has grown back. About 1 - 3% of the scalp hair is in the growth stop (catagenic phase) and 10 - 15% in the telogen status, i.e. the latter has not grown for about 6 months and then falls out. In the hair analysis, catagenic and telogen hair are the so-called "contaminated sites", as they contain the stored substances before the start of your abstinence and are included in the hair analysis.

(II) behaviors, final consumption

It should be noted that scalp hair is in a relatively "unprotected position". This means that they are exposed to environmental influences such as B. Exposed applications for dust (cocaine) or smoke (cannabis). It is also possible to apply substances to the hair matrix via sweat and sebum. The indication of passive consumption cannot be taken into account in the fitness to drive diagnostics. Therefore, adjust your behavior in the time before the planned hair removal. Before carrying out a hair analysis for narcotics, it must be clarified when the last consumption took place, as the storage of these substances from the body's own depots (e.g. fatty tissue) can take place a few weeks after the end of consumption. The assessment criteria for fitness to drive therefore recommend examining only those hair segments that correspond to a period of at least 3 months after the last consumption. In cases of chronic consumption, a longer period of up to 6 months can be useful.

1. Alcohol abstinence by means of hair analysis

1.1 Receipt of a alcohol-Abstinence

A hair segment with a maximum length of 3 cm is used to examine hair for the alcohol metabolite "ETG"
- measured from the scalp - accepted in accordance with the assessment criteria for fitness to drive [1]. This corresponds to a proof of abstinence of 3 months. If the hair is shorter, only a period of 1 month can be retrospectively assessed per centimeter of hair.

For a 6-month abstinence certificate, at least 2 hair analyzes are required, and if you have been abstaining from alcohol for a year, at least 4 hair analyzes are required (see figure). If, for example, a second hair analysis is to be carried out after the first hair analysis after 3 months as evidence of abstinence, the hair samples from the first and each subsequent collection must be examined separately. The collection of hair samples is not permitted.

1.2 Hair treatment: coloration, coloring, bleaching in case of alcohol abstinence

Important: Your hair can be tested for ETG from the scheduled examination NOT bleached, colored, dyed or otherwise treated be. This means that with a three-month certificate of abstinence from alcohol, your hair must not have been tinted, dyed or bleached for three months. In the case of highlights, we can remove untreated sections of hair (as far as practicable). If there are not enough sections of undyed hair available, an examination is not possible.

If a hair treatment is not specified and only proven during the analysis in the laboratory, a negative hair sample cannot be considered as evidence of abstinence. The cost of the examination is non-refundable.

1.3 Notes on alcohol in food, cosmetics and pharmaceuticals:

In addition to abstaining from alcoholic beverages, foods containing alcohol such as B. Tiramisu, wine sauces, various types of vinegar (especially balsamic vinegar), confectionery (pralines, etc.) are not consumed because we cannot determine the origin of the alcohol consumed. Mouthwash containing alcohol and over-the-counter herbal medicinal products based on alcohol (e.g. Iberogast®, Echinacin drops) must not be taken as they lead to the detection of ETG in the hair. Please note that so-called "non-alcoholic beer (including sparkling wine / wine)" and naturally cloudy juices (e.g. apple juice) may contain small amounts of alcohol.


2. Narcotics (BtM) abstinence by means of hair analysis

2.1 Evidence of abstinence from BtM

Screening for narcotics got to in accordance with the criteria for the chemical-toxicological examination (CTU) in the diagnostic of fitness to drive, be poly-toxicological - i.e. geared towards various narcotics. It includes the substance classes of cannabinoids, cocaine, amphetamine and derivatives, methadone, benzodiazepines and opiates.

In the case of previous opiate addiction, the research assignment must be extended to the group of opioids (buprenorphine, tilidine, oxycodone, tramadol and fentanyl including metabolites). Please let us know - if applicable - in front carrying out the hair analysis.

For the polytoxicological examination of hair for anesthetics, an untreated hair segment with a maximum length of 6 cm, measured from the scalp, is accepted. This corresponds to a period for the verifiability of a maximum of 6 months. For a one-year proof of abstinence, at least 2 hair analyzes are required (see figure). These hair samples must be examined separately, "collecting" hair samples for examination is not permitted.

2.2 Hair treatment: coloration, coloring, bleaching in the case of BtM abstinence

In contrast to proof of alcohol abstinence, proof of abstinence for narcotics is possible by examining colored / tinted hair. As with untreated hair, up to 6 cm can be examined for this. So that a total of one year of abstinence can be proven, the hair analysis from tinted / colored hair must be supplemented by a 6 - month urine control program prior to the assessment (see figure). Alternatively, a second hair analysis can be carried out. In any case, this must be done from untreated hair. If the hair of the second sample was treated anyway, a negative hair sample cannot be taken as evidence of abstinence. The costs of the examination cannot then be reimbursed.

2.3 Notes on the consumption of cough syrup and poppy seeds

Foods containing poppy seeds (poppy seed cakes, poppy seed rolls, poppy seed yoghurt) may contain small amounts of morphine. These foods must be avoided as they can produce a positive opiate test result. Codeine in cough syrups is converted to morphine by the body. Even when taking cough syrup, it cannot be ruled out that in addition to the storage of codeine, morphine will also be stored in the hair and that the hair analysis will test positive for opiates.

3. Type and number of (hair) analyzes in abstinence control

The graphic below gives you an overview of the evidence of abstinence by means of hair analysis for a one-year program in alcohol or narcotics abstinence, taking into account colored / dyed or untreated hair.


4. Taking a hair sample for forensic purposes

(Fitness to drive diagnostics (MPU), probation conditions, medical reports)

To obtain analysis material, the Scalp hair preferably in the area of Occipital hump one at a time pencil-thick strand of hair twisted together. Everyone who both Strands of hair (sample and Retention sample) are secured with a thread to prevent slipping on the head. The strands of hair will be just above the scalp truncated and pending analysis in Aluminum foil struck. The side near the scalp (proximal) is marked. The hair length to be examined (measured in centimeters) and the one on the head remaining hair length (measured in millimeters) are documented in the investigation order. Each hair sample taken must be from at least 100 mg of material consist. Please use our to send in the hair sample for examinationInvestigation order.



5. Forensically accredited analysis of hair, urine and blood samples

The laboratory of Prof. Enders MVZ is in accordance with DIN EN ISO / IEC 17025: 2018 for narcotic analysis from blood (serum, plasma), urine and hair for forensic purposes including aptitude tests accredited (certificate).
