Although we have endeavored to be thorough and discuss different circumstances that may arise, it is still important to note that Child Protection Practitioners may still require to discuss the results of specific screens with ACL directly.  \n1. What identification does a person need when they attend for a screen?  \n􀁸 Australian Driver’s License  \n􀁸 Passport  \n􀁸 Victorian Proof of age card  \n􀁸 Key Pass card (issued by Australia Post)  \n􀁸 Statutory Declaration with photograph-only valid for 4 weeks from date of issue  \n􀁸 Department of Health and Human Services letter with photograph – only valid for 4 weeks from date of issue  \n2. Why is urine the most commonly obtained specimen for drug testing?  \nDrug testing can be completed on various biological specimens including urine, blood, hair, saliva, sweat, and nails. However, urine testing is the preferred method for a number of reasons:  \n􀁸 Urine testing is noninvasive and easily to collected.  \n􀁸 Drug detection times are also longer in urine than in blood and can range from 1 day and up to several weeks.  \n􀁸 Both parent drug and metabolites can be detected in urine samples and are in higher concentrations than in blood samples. Parent drug refers to the broad class of which the specific drug belongs to; metabolite refers to the form of the drug after it has been processed by the body, also referred to as by-product. For example Codeine’s metabolite is morphine, therefore Codeine is the parent drug.  \n3. What is sample check and why has it failed?  \nA sample check is a system of steps the laboratory undergo before screening the sample, it includes checking creatinine levels, which are reported, checking temperature at time of production, colour of urine and oxidation levels. Sample check detects elevated amounts of oxidants in a urine sample. Oxidizing agents (i.e. a substance that has the ability to combine with other substances causing them to lose electrons) such as hydrogen peroxide, nitrite, glutaraldehyde and bleach are not found in normal human urine. Therefore any urine sample containing elevated levels of oxidants may indicate tampering (known as adulteration) and cause a failed sample check. Adulteration is the action of tampering with the sample or affecting the purity of the specimen. However it is important to note urine specimens from people who take supplements that contain concentrated cranberry extract or Vitamin C may also fail the sample check test, rather than the sample having been deliberately tampered with.  \n4. What does the creatinine result mean?  \nCreatinine is a by-product of muscle tissue. Under normal circumstances a consistent amount of creatinine is excreted in the urine per day. If a person is passing only a small amount of urine per day then the concentration of creatinine in the urine will be high. Conversely if a person is passing a large volume of urine, the concentration of creatinine will be low.  \nThe creatinine level can also be used as a marker to determine whether the sample is true human urine and whether the urine sample is diluted or has potentially tampered with. Diluted urine may occur for a number of reasons, including the following:  \n􀁸 Person may have recently drunk a large volume of fluid.  \n􀁸 Person may have a medical condition which results in the production of large volumes of urine e.g diabetes or other renal diseases.  \n􀁸 Person may be taking a drug such as a diuretic which cause an increase in urine output.  \n􀁸 Water may have been added to the specimen container to try and reduce the concentration of possible illicit substances.  \nIf the laboratory finds a creatinine result, which is lower than expected, then a comment is added to the report indicating this and advising this may result in a negative test results.
