Most Common Drugs Detected in Urine Drug Testing and What They Mean

Urine Drug Testing

When it comes to urine drug testing, certain drugs are tested more often than others. Opioids, sedatives, stimulants, barbiturates, benzodiazepines, and other controlled substances are among the most commonly tested medications. Hydrocodone and oxycodone are some popular opioids tested.

The length of time a drug stays in the body varies based on its class. Opioids remain detectable for up to three days. However, benzodiazepines can be detected up to four weeks, and stimulants like amphetamines for up to seven days. Furthermore, barbiturates last even longer. It’s hard to hide small traces of drugs, as laboratory tests can detect even small amounts. However, it’s always important that the person being tested lets the lab know any OTC medications and other medications they are taking. This will help with giving the most accurate results possible.

Alcohol consumption, anabolic steroid use, and cancer treatments can also be detected through urine and blood testing in certain circumstances. Keystone Lab’s’ stringent standards regarding accuracy and precision, combined with cutting-edge technology and trained professionals, guarantee accurate, reliable results. We have strict protocols to ensure our clients get the most accurate results possible. If you have a business that needs to have its employees tested, we would be happy to help.
