Hair Testing

How does it work?

Hair testing identifies drug and alcohol markers both inside and outside a shaft of hair. When the sample arrives in the laboratory for testing, it is first washed to remove external contamination before any testing takes place. Then, as well using cut-offs, the detection of metabolites is further confirmation of actual consumption every bit opposed to contamination. In the example of drugs, the examination allows the lab to measure the number of drugs and their metabolites in the hair shaft. For alcohol, it establishes whether certain biomarkers of booze consumption are nowadays in the hair. Learn more about the process here .

Substances are able to pass into the nail as it is formed and from the blood vessels under the nails into the keratin fibres of the nails themselves and become trapped. As the nails grow longer and thicker, the layers provide a history of substance apply. Testing can exist conducted in 2 different ways, either using immunoassay screening followed by a confirmation test, or with liquid chromatography and mass spectrometry .

Sampling all ten fingernails could produce a sample weight of 100mg. If the fingernails are non sufficiently long, samples can be taken from the toenails instead.

The donor clips the samples in front of a trained collector, using clippers that have been cleaned and after washing their hands and cleaning under their nails. The sample is secured in a conspicuously labelled envelope, before beingness sent to the lab for analysis.

What are the benefits of fingernail testing?

Fingernail testing - unlike urine and blood testing - can exist used to test within a timeframe of months, rather than days. A three millimetre sample of nail can provide an exposure history of up to (approximately) 8 months. A 3 millimetre fingernail clipping might represent half-dozen months and the same from a toenail 12 months.
