What is a urine drug test?
A urine drug test is a test for detecting an illicit substance of abuse by sampling urine. This method detects specific drugs of abuse in various options and formats. Options vary from a single panel–one drug to a fourteen panel–fourteen drugs. Current formats are an analysis dip card or an analysis specimen cup.
Most tests are designed to detect the parent drug or a metabolite of the consumed substance. When a drug is consumed, the body metabolizes that drug into a modified form. For example, Cocaine is metabolized by the body into benzoylecgonine, and Opiates are metabolized into Morphine. A urine test is designed to detect these metabolites to determine abuse.
How does it work?
The first stage of a test starts with the screening process. The image ‘above’ shows a basis of what a screening device looks like. It comprises two parts; chemically coated strips and the case or card which encapsulates it. Each strip is unique and detects a specific substance. The most popular substances are Cocaine, Amphetamines, Methamphetamine, Opiates, and Marijuana.
Screening devices come in two variants; a dip card or a cup. Each works the same, but the process is slightly different. A dip card has external test strips which are dipped directly into the urine. A cup has internal strips located around the inside wall of the cup. With this method, the person urinates directly into the cup, and then the collector/administrator observes the analysis as it progresses.
In conclusion, so you now you know what is a urine drug test–a low cost method for detecting the abuse of many different illicit substances from an individual by sampling their urine.
