The toxicological analysis of your hair is carried out in our high-tech laboratory in France.

LC-QTOF: Liquid chromatography analyzer coupled with quadrupole time-of-flight tandem mass spectrometry.

ICP-MS: Inductively coupled plasma mass spectrometry.

Any questions?

How can analysing my hair enable me to find out my chronic exposure to pollutants?
Hair constitutes a sort of biological memory which allows for the identification and dating of a possible exposure to one or several toxic substances.
Pollutants, absorbed by our bodies, are carried in our blood.
Hair uses blood to grow, and the pollutants are automatically captured in the hair.
Why does a toxSeek analysis need a 3 cm length of hair?
We advise you to carry out a toxSeek analysis on a 3 cm length of hair, starting from the root. This is equivalent to about 3 months’ exposure to pollutants.
It is, however, possible to analyse a length of hair as short as 1cm; the results will indicate exposure over 1 month. To summarise, the test remains effective on 1cm but a 3cm length will provide more information.
What will happen to my hair sample? Will it be kept? And my DNA?
The hair undergoes two extractions (solvent and mineralisation), thus altering its protein structure. The DNA is simply broken down.
Once the hair has been prepared, the altered residue is destroyed in specific containers for clinical waste, which are in turn incinerated.
Can hair dyes, capillary treatment or external pollution affect toxicological analyses?
Hair dyes and treatments using oxidisers such as hydrogen peroxide have a direct influence on the quality of the analysis of organic pollutants, as they are distorted by the oxidising substances and therefore made impossible to detect.
However, these oxidisers have no effect on our toxicological metal analysis. Other types of treatment, for example simple ammonia-based hair colouring, have no impact. Our procedures are not affected by external pollution sources because the cleaning of the outer part of the hair is an integral part of our procedure.
How is the sample of my hair taken?
It’s very simple. You receive a hair sampling kit to use at home, at your convenience. You need to cut a strand of a diameter of 1 mm (around 50 to 70 hairs) from the root, a process made easier with our sample measuring tool. We provide you with precise instructions in our tutorial, from cutting the hair to inserting it into the toxSeek tube contained in the kit.
How long will it take to receive the results?
After we receive the samples, it takes around 20 days for your toxicological analysis report to be sent to your customer account. (The protection of your personal data is optimised on our secure site, hosted on a special server approved for storing health data). You will be informed by mail when your report becomes available.
I have several children, should I test them all?
Even if they live close together, children all have their own habits, schools, clothes, and favourite food and drink. It’s also worth noting that different children won’t have the same reaction to being exposed to various toxins. Toxic absorption is very often different for each child of the same family. We therefore recommend you carry out the toxSeek test on each of them to identify any shared and individual sources of exposure.
