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.
A lot of different drugs can be found through these methods. The time frame of detection will vary based on many things, including: metabolic rate, drug class, age, body mass, overall health, urine pH, amount taken, and frequency of use. The metabolites are expected to stay in the system longer than most parent drugs. For instance, cocaine and heroin can only be found through these results for a few hours after the use, but their metabolites can stay in the urine for days.
Saliva and oral fluid test results are similar to that of blood, with a couple exceptions. Breath air can also mimic accuracy of blood tests. Generally speaking, most hair tests have a long detection period of days, usually between 2 and 90.
Urine tests are done to screen for both metabolites and parent drugs. These determine if these things are present in the system, but not when they were taken or the amount. This is the typical approach used by employers screening employees. Usually they will be sent to a collection lab where the sample will be taken. This is guarded to ensure there is no tampering done or other disruptions caused by employee mistakes.
Court systems often employ hair analysis. This is considered admissible evidence, legally and scientifically. Many drugs can be tested using samples of hair, such as cocaine, ephedrine, amphetamines and cannabis.
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.
