A urine drug test, also known as a urine drug screen or a UDS, is a painless test generally administered by a health care professional who is trained in the proper procedures of collection and interpretation of results. The test cup strips analyze urine for the presence of drugs and prescription medications using an absorbent lateral flow membrane that reacts to the presences of drug metabolites in the urine. Depending on the configuration of the strips on the cup, a single test can screen for up to 18 substances from a single specimen. The urine drug test usually screens for drugs of abuse but can also be used to ensure compliance with prescribed medications. The UDS is a quantitative test. Quantitative testing measures the amount of a substance present in a urine sample. Each individual test strip has a cutoff level in most cases determined by the FDA. A “cutoff level” is the minimum amount of a detectable substance that will trigger the test strip to indicate a “Positive” result. It is critically important to remember that any “Quantitative” test will only indicate the presence of a substance. A “Definitive” test which is run on highly complex scientific equipment monitored and managed by Forensic Toxicologists is the only way to define exactly what levels of the substance are present in the sample provided by the donor. Definitive tests are much more expensive than a UDS but are necessary to confirm that the person providing the specimen has used a drug of abuse to a degree of 99.999% certainty.
A urine drug test can help detect potential substance abuse problems. After a drug test identifies drugs that may have been misused or abused, a loved one can help the individual start a substance abuse treatment plan. At home Urine Drug Test Kits are a safe, discreet and effective way to determine if a potential problem exists.
