Hair Drug Testing

As the only lab in New Zealand to offer Hair Drug Testing, Hills Labs follows the Society of Hair Testing (SoHT) guidelines and uses European Workplace Drug Testing Society (EWDTS) cut-off recommendations to ensure accurate and reliable results. Hair drug testing is a reliable method used in a variety of contexts including family law cases, pre-employment screening, return-to-work investigations, and compliance monitoring.  

What substances do we test for in hair samples? 

This type of testing helps determine the consumption of drugs over time, offering a longer detection window than other biological samples. We offer testing for a wide range of drug groups and alcohol markers over various time periods. Drug groups available include but are not limited to: 

  • Amphetamine Type Substances (ATS) 
  • Cannabinoids 
  • Opiates and opioids 
  • Cocaine and metabolites 
  • Benzodiazepines 
  • Ketamine and metabolite 
  • Methadone and metabolite 
  • Alcohol markers: Ethyl Glucuronide (ETG) and Ethyl Palmitate (ETP)

What type of samples are used for hair drug testing?  

  • Head hair is the preferred sample type. 
  • Body hair may be used when head hair is unavailable. 
  • Alcohol marker testing is available only on head hair. 

How long does it take to get results for hair drug testing? 

We carry out testing on behalf of collectors based around New Zealand, and provide detailed reports within 10 working days of sample receipt.
