About Hair Drug Testing

Hair strand testing involves collecting and analysing hair to detect the presence of drugs and alcohol. This method is particularly effective in identifying individuals who engage in prolonged drug use, as opposed to one-time users.

Unlike other drug testing methods, hair strand testing has a longer detection window, allowing for the assessment of an individual’s drug use history.

Hair strand testing provides the most accurate timeline. Head hair is the ideal option, however body hair (legs, arms, underarms) can be collected where there isn’t enough. Hair analysis can accurately detect drug use history for a year or more as long as the sample provided is long enough. Each 3.6cm hair sample provides a 90-day history of drug use.

About Fingernail Drug Testing

Did you know that if hair is dyed, it can compromise the integrity of drug tests?

Fingernail testing is a great alternative when hair is potentially compromised, meaning it has been coloured or treated. It’s also an option for those who don’t have hair long enough to be tested!

Fingernails, similar to hair, are made up of keratin. During their formation, substances can permeate the nails and become trapped within the keratin fibres from the underlying blood vessels. As the nails grow, the layers serve as a historical record of substance use.

Nails serve as a secondary method when there is inadequate hair available for the required time period.

Fingernails provide approx. 6 months detection, toe nails provide approx. 12 months. Nail testing is less accurate on the timeline as nail growth rates have greater variability.
