Dorevitch Pathology operate a network of Laboratories throughout Victoria and South Australia which have been NATA Accredited to AS4308 and AS4760 standards. As part of the Healius network, we can provide a national solution to employers from design of the drug and alcohol testing program through to the interpretation of results.
There are several sample types which are suitable in some circumstances for drug monitoring programs. All have their strengths and weaknesses and the choice of the particular matrix is best determined in consultation between employers, employees/unions, and WHS staff or consultants.
If the industry has no previous experience with this testing, it is often advisable to contact an occupational health consultant or an accredited laboratory to obtain specific guidance regarding setting up and managing testing procedures.

Instant Drug Devices available through Healius Pathology are verified and validated by the Laboratory as fit for purpose in accordance with AS4308 for Urine Devices or AS4760 for Oral Fluid Devices. These can be purchased directly for use by the employer, the individual for home self testing or can be used for testing at your workplace by certified Healius collection staff.
If the screening test (instant or laboratory screening) indicates the possible presence of a drug (a non-negative result), a liquid chromatography mass spectrometry (LCMS) confirmation test is performed. It is a more sensitive and specific method with the purpose of eliminating any false positive results , to define which specific member(s) of the drug class is (are) present, and to determine how much is present.
Advantages and disadvantages of Urine Vs Oral fluid
What's best for your company?
Urine
Oral fluid
Drugs detected (screening)
Urine
Opiates
Amphetamines / Methamphetamines
Cannabis
Cocaine
Benzodiazepines
Oral fluid
Opiates
Amphetamines / Methamphetamines
Cannabis
Cocaine
Benzodiazepines*
Oxycodone
Benzodiazepines are not specifically listed in the oral fluid Standard but they are commonly requested and legitimately reported because of an expectation arising from urine testing as well as requirement in the Australian Government Building Code 2013
Detection times
Urine
Generally 3-4 days
Oral fluid
Generally 3-12 hours
Positives
Urine
Generally 3-4 days.
Longer window of detection which will detect drug use when behavioural risks are significant.
Adulterant checks in place for urine i.e. temperature, creatinine, pH, Oxidants and visual inspection.
Takes between 4-7 minutes to collect and perform instant test.
All persons produce urine.
Less expensive for both screening and confirmation testing.
One void is sufficient for all testing.
Oral fluid
Generally 3-12 hours.
Less invasive.
Do not need special collection facilities.
Testing for parent drug versus metabolite in Cannabis, thus less historical.
Negatives
Urine
Special collection facilities required.
THC looks at metabolite which can give historical use after quitting use for up to 3 months.
Oral fluid
Shorter window of detection which align more closely with more recent use which may fail to detect drug use when behavioural risks are significant.
Salive may be diluted, corrupted or neutralised by brushing teeth/mouth, using mouthwash, smoking.
