Urine Drug Testing

What is urine drug testing and how is it performed?

Urine drug testing is the most common type of drug test performed today. Urine testing is typically performed to show recent or current drug use. Depending on the drug and frequency of use, detection times can vary from a few hours to over a month.

Urine samples are typically collected in a closed bathroom or bathroom stall while the collector waits outside of the bathroom unless the test is to be observed. In observed testing, a trained observer of the same gender will accompany the donor into the bathroom or bathroom stall and will ensure that the donor does not tamper with or substitute their sample.

Who should choose urine drug testing?

Urine drug testing is usually performed when recent drug use is suspected. Because each drug varies in detection time with urine testing, it is important to know what those approximate detection times are so that testing can coincide with suspected use times. Our staff can help you determine these detection times.

How we can help.

We can provide a wide array of urine tests that are confidential and court defensible. Urine drug testing services are available to concerned parents, attorneys, corporations and private individuals. Results can be released to multiple individuals if necessary and in some cases can even be performed anonymously.

In situations where donors are living in other states or even overseas, we can coordinate the collection of their samples where each donor resides.

Frequently Asked Questions
Do I need an appointment for a urine test?

It depends. Appointments are required for urine testing if the test is to be observed. If the test isn't observed, then no appointment is necessary, walk-ins are welcome.

How long will the collection take?

Urine collections where the donor is able to provide an immediate sample take approximately 10 minutes.

I take a lot of vitamins, will this affect my result?


I'm supposed to take an observed collection, does that mean someone will be watching me while I provide my specimen?

Yes. Specific details about observed collections can be viewed here so you know what to expect. You can also ask the collector or observer at any time what the guidelines are.

Should I drink a lot of water before my test?

You should drink the same amount that you would normally drink.

What is a testing panel, and how do I know which one to pick?

A testing panel is simply a drug or a class of drugs that should be tested for. The best option for help selecting a panel is to call us at (636) 916-0050. If you prefer, you can view a list of the most common urine testing panels in our online reference library.

In some cases, testing may already be set up. To check if testing has already been set up for you, call us at (636) 916-0050.


If testing hasn't been set up already, it will need to be set up before any appointments or specimen collections can be made. To make the set up process quick and accurate, make sure that you have all of the necessary information first.


To set up your test you will need:


  • If the test is to be observed or not
  • The test panel to be performed or a complete list of drugs that should be tested for (trade names such as Adderall are acceptable for prescription drugs)

If you do not have all of the information, or are unsure about the information that you do have, please let us know this when setting up your test.

Appointments are suggested but not required.

Payment is required at this time unless arrangements have already been made. Prior to arriving for your appointment, please be sure to bring with you:

Discussing your results with the doctor

Some results may require a doctor to contact you prior to releasing the final result.

In some cases where a donor is taking a legitimate prescription drug, a false-positive may occur. Instead of releasing the result as positive, you have the option of having a special medical review officer (MRO) contact you to discuss your result for an additional fee. If you decide to have your result reviewed, you should take this opportunity to provide any prescription medication information to the doctor that may explain a positive result.


At the end of the conversation, the doctor should be able to provide you with their final determination and will then release the results for reporting.


If any positive results are explained by valid prescription use, the final result will show "Negative" for that drug instead of positive. If no prescription information is provided, or the prescription provided would not have affected the result, the final result will still show "Positive" for that drug.


You will not need to worry about contacting the doctor directly. If you decide to have your test reviewed, the doctor will contact you first.


If you miss the doctor's call, or are unable to discuss the information with the doctor when they call, they will leave a call back number on any voice-mail or answering machine service. It is important that you call the doctor back as soon as possible. If you fail to return the doctor's call within 72 hours, the doctor may release the result without giving you the opportunity to provide any information.

Obtaining your results

Test results are normally available 1 to 2 business days after collection.

Telephone and fax results are typically available 2 days after the specimen is collected. A mailed test result is provided and typically arrives in the mail 7 to 14 days after the specimen is collected. Donors can also request to hold results at our Saint Charles office for pickup. Results are typically available for pickup 7 days after the specimen is collected. If you would like to pick up your result instead of having it mailed, please tell your collector during your appointment.


For help interpreting your results after you receive them, please call (636) 916-0050 and one of our staff would be happy to discuss your result with you.

Have Questions?

Drug testing can be embarrassing to discuss. We understand.

Normally drug testing is performed for reasons that can be embarrassing. Simply knowing that you need to take a test, or that you need to have someone test, can be stressful before you even pick up the phone to call for information. After providing your sample you have the added anxiety of waiting for the test result to come back. We understand that you will have questions and concerns. We want you to know that we will be here each step of the way to help you, even after the test results are back. If you have any questions about the testing process, help interpreting your results or would like information on where substance abuse treatment can be obtained, please give us a call.
