There are a number of commercially available urine testing kits that give a guide to the presence of illegal/inappropriate drugs within 10 minutes. Over the past 2 years I have supervised 1,816 medical assessments in Queensland and NSW for a major project in Brisbane. The assessment included urine drug screening using a dipstick test. One hundred and seventy three (173) applicants tested positive and of these 90 (or 52%) failed a subsequent full pathology laboratory urine test. In other words 83 or 48% passed on further testing.
This program was completed without any industrial relations problems and no challenges to the testing procedures or results.
