Toxicology Testing

A toxicology test (“tox screen”) checks for drugs or other chemicals in your urine. Drugs can be swallowed, inhaled, injected, or absorbed through the skin or a mucous membrane.

A tox screen may check for one certain drug or for up to 30 different drugs at once. These may include prescription medicines, nonprescription medicines (such as aspirin), vitamins, supplements, alcohol, and illegal drugs, such as cocaine and heroin.

Testing is done on urine instead of blood. Many drugs will show up in a urine sample and urine and tests are usually easier to collect than blood tests.

Urine toxicology does more than provide useful results, it can also protect your medical or clinical practice from legal action. We provide comprehensive urine toxicology services you can use for many reasons, including carefully monitoring of patients who are prescribed opiate (narcotic) pain medications.

There are many potential reasons why a medical professional may order a urine drug screen (UDS) for a patient. A primary care physician (PCP) may order a UDT if it’s suspected that a patient may have a substance abuse problem. An emergency room doctor may order a UDT if a patient is acting erratically. Drug and alcohol rehabilitation centers may require participants in inpatient or outpatient programs to have periodic tests. Additional reasons could include:

  • Monitoring a patient’s medication adherence
  • Screening for possible drug interactions
  • Patients coming to their doctor for a routine employment-related urine screen
