Hair testing by HASTA

Extend your window of detection.

HASTA is pleased to introduce Hair Testing to our human drug testing portfolio. The advantage of hair testing is that it can detect drug use over an extended period, compared to the traditional urine or oral fluid tests, and provide evidence of chronic use. Drugs are detectable from 1 week up to 6 months after use. The methods are highly sensitive, and results are admissible for medico/legal proceedings.

HASTA offers two comprehensive screening tests:

Drugs of Abuse: we can test hair for over 60 common drugs of abuse, including both illicit substances and prescription medication.

Anabolic Steroids: we can also now test hair for over 45 known steroids


Workplace Drug Testing

Maintain the integrity and reputation of your workplace


Having an effective drug testing program protects both the reputation of your company and the safety of your workforce.  Through RASL, HASTA can provide fast and efficient testing for illicit drugs in urine and oral fluid. Drug screening and confirmation are performed to AS/NZS 4308:2008 and AS/NZS 4760:2006 standards. We can also provide specialty services, such as comprehensive testing for synthetic cannabinoids and designer drug variants.

What should be tested -

Hair, oral fluid or urine?

Drugs are detected in a number of sample types for different lengths of time, so it is important to test the right sample. Depending on your Drug and Alcohol policy, you may want to test to control drug use in the workplace, or ensure complete abstinence from illicit drug taking.


Oral fluid has the shortest detection window and indicates the most immediate evidence of drug use, with detection from 6 hours to 24 hours, depending on the drug.


Urine offers longer detection windows, with some drugs detected for up to 10 days after use.


Hair can detect drug use over an extended period, and provides evidence of chronic use. Traces can be detected after 7 days and can remain for up to 6 months, depending on the length of hair.

HASTA is NATA accredited for testing human urine, oral fluid and hair giving your workplace clients a full range of testing options
