Know About Laboratory Urine Drug Test

Many types of drug testing techniques are available for detecting drug abuse. Urinalysis is one of the most commonly used urine based drug testing as it is a simple technique, and less expensive. Urine drug testing has been popular and employed successfully for testing drugs across the organizations, schools, at home etc.
Drugs tested Laboratory urine drug testing detects the presence of many drugs with accurate results. This drug testing can detect maximum of 10 most commonly used drugs at once. It detects the parent drug or its metabolites by demonstrating recent use of prescription medications like opioids, benzodiazepines, amphetamines, barbiturates and illegal substances like heroin, illicit cocaine, marijuana, phencyclidine (PCP). This test is used as a screening tool to determine the prior use and concentrations of drugs present in the body.
Procedure followed For laboratory urine drug test, collection and testing urine specimen is done under the presence of an authorized person. After this, tests are conducted on collected specimen for detection of drug tests by immunoassay screen followed by GS-MS confirmation test. Chemical highlighted test strip is used for this test. The test strip should be examined carefully with the help of lab testing devices depending upon the types of substances to be detected.
For each drug the detection periods and cut off levels depend on the nature and usage of the drug. The detection period of any drug through laboratory urine drug testing is from 6 hours to 3 days from the time of consumption. All screening tests are performed by the immunoassay based on the technology of the testing kit. Confirmatory tests are performed using either gas chromatography/mass spectrometry (GC/MS) or any other superior technique. The samples are treated with either the technical or all of these methods to verify the results. Confirmation results are reported as positive or negative based on SAMSHA cut off levels and all non-negative results are confirmed prior to any disclosure. Laboratory urine drug test is used as standard test for drug detection. Reliable results are possible with this laboratory drug testing and they can be used as a proof drug abuse. The above information gives you a helpful insight about the laboratory urine drug test, drugs detected through this and the procedure followed.
