Urine Drug & Alcohol Tests

The drug metabolites tested for in urine drug screening kits are stored in the kidneys and excreted from the human body via urine. Urine drug screening kits test for the level of drug in the urine specimen and will indicate a presumptive positive if the level is above the prescribed cut-off level recommended by Australian Standards AS/NZS4308:2008. Some metabolites may be stored in the kidneys for up to 2 months eg. THC and therefore remain detectable during this time.
Oral Fluid (Saliva) Drug & Alcohol Tests
Oral fluid drug test kits detect up to the past 12 hours of drug use and are used for Random drug screening in workplaces to identify whether someone is currently under the influence of drugs or alcohol.
Oral fluid tests detect metabolites and parent forms of drugs in oral fluid via the mouth. Metabolites (broken down form of a drug already processed by the body) are present in saliva and are said to be a 1:1 ratio of the level in the blood. The Parent form of THC is also tested for which is the unprocessed form of the drug and would be present in the oral cavity after having recently smoked a joint.
