QUESTION & ANSWER

A drug screen may also be used to detect performance-enhancing drugs sometimes used by professional athletes such as steroids and HGH. Many different
types of drug screens exist for multiple purposes.
Types of Drug Screens
Urine Drug Screen
Urine drug screens are the most popular, making up 95% of the employment drug screenings conducted in the United States. Its popularity is due to its low cost and simple collection process. The specimen collection usually happens at a clinic or testing facility, and the sample is then sent to a lab for screening. Depending on the type of panel test, the results will show either false or positive for a specific set of drugs.
Testing for alcohol provides a scientifically proven method to monitor an individual's alcohol use over a period of time. EtG appears in the urine less than 60 minutes after alcohol consumption, and its maximum concentration is reached after 5.5 hours. These values are similar to those in the blood, but EtG can be detected in the urine 24 hours after the consumption of small amounts of ethanol and more than 5 days after the consumption of large amounts of ethanol.
