As a leading provider of UKAS-accredited drug and alcohol testing, and a trusted training partner of the Judicial College, AlphaBiolabs recently had the opportunity to deliver a session on drug and alcohol testing to over 80 members of the judiciary.
Among the many insightful discussions that took place, there was a noticeable interest in alternative testing methods to complement hair testing – particularly nail testing.
Here, we take a closer look at nail drug and alcohol testing, its evidential value and how it can be used to support or enhance other toxicology evidence.
Nail testing is a toxicological method used to detect drug use or, in the case of nail alcohol testing, to monitor abstinence or chronic and excessive alcohol consumption over an extended period.
When a person consumes drugs or alcohol, these substances and their metabolites enter the bloodstream and become embedded in the keratin fibres of the nails as they grow.
Once deposited, these markers remain stable, providing a retrospective overview of substance use.
Nail testing is especially useful when hair testing is unavailable or unsuitable. Common scenarios include:
In such instances, nail testing provides a robust alternative. It is also highly relevant in child protection cases, where long-term patterns of drug or alcohol use need to be evidenced swiftly to inform safeguarding decisions.
While nail testing can be conducted independently, its evidential power is amplified when used in conjunction with other testing methods. Combining nail drug or alcohol testing with hair, blood, urine or oral fluid analysis allows legal professionals to:
In alcohol testing, nail samples can complement blood biomarker testing – such as phosphatidylethanol (PEth) – to build a multi-source profile of alcohol use (proof of abstinence or supportive of chronic and excessive use). This is particularly valuable in care proceedings where establishing long-term parental behaviour is critical.
As toxicological science evolves, it’s essential for the legal profession to remain up to date on the full range of testing options available, particularly when decisions in court can have far-reaching consequences for families.
Nail testing offers a reliable means of evidencing long-term substance use and is effective as:
