What To Know About Drug Testing Brisbane

By Olivia Cross


Varying situations may call for the testing for drugs in a person. A drug test is the analysis of biological samples to check for the absence or presence of metabolites or their parent drugs. This might be done using different specimens taken from a person, including: saliva, sweat, urine, breath, blood or hair samples. Drug testing Brisbane is available through many sources for those living in this area of Australia.

Testing could be done to check for steroid that enhance performance in athletes. Employers may also screen current or potential employees to see if there are illegal drugs present in their system, including cannabis, cocaine and heroin. Often police officers will test for alcohol presence, as well as the concentration of alcohol within a person. This is also known as BAC and most of these tests are issued through breathalyzer. Urinalysis is often reserved for sports or workplace testing.

Many different drugs might be detected through the process. There are certain windows of detection that might be based on certain things, such as: frequency of use, metabolic rate, age, amount taken, drug class, body mass, urine pH and overall health. The time of detection for metabolites is often longer than the parent drug. For example, heroin and cocaine are only detected through the system for a few hours after they have been used, but the metabolites might stay in urine for days.

Saliva and oral fluid test results are like those one by blood, although there are some differences. Breath air can also produce similar results to blood tests. Generally, many of the hair tests will have the longest period of detection, with results showing for two to 90 days after the initial drug use.

Urine tests screen for parent drugs or their metabolites. These simply detect whether or not these things are present in the system, not how much or how long. This is commonly the approach used by employers who want to screen their employees. Generally, these people will be sent to a special collection site to have the test performed and will be given instructions on what to do. The sample given is watched over to ensure there is no tampering or invalidation that occurs by any parties involved.

Analysis of the hair is commonly done by the court systems. This is recognized as legally and scientifically admissible evidence. Numerous drugs can be tested through samples of hair, including cannabis, cocaine, ephedrine and amphetamines.

Presumptive substance testing is also available. This is often available through over-the-counter kits and does not require professional labs. It involves using materials, surfaces or substances to detect trace amounts of illegal substances. This can be done rather than testing the biological specimen of a person. To perform this, the suspicious material is mixed with a chemical. If the response is a certain color change, drugs are considered present.

This kind of presumptive testing is ideal because the person who is being tested does not need to know. In fact, only a small amount of material is needed to get results. The tests are for screening purposes only and offer generic results. Nonetheless, they can be used to detect a number of drugs. It is essential to employ professional labs and testers to get the most accurate results.
