Instant Urine Drug Testing

What is instant urine drug testing and how is it performed?

Instant urine drug testing is typically performed to show recent or current drug use and to provide a result instantly. Depending on the drug and frequency of use, detection times can vary from a few hours to months.

Urine samples can be collected in a clinical setting, a workplace or in a private residence. The urine is collected in a test kit cup and results are read within a few minutes.

Who should choose urine drug testing?

Instant urine drug testing is usually performed when recent drug use is suspected and a laboratory test isn't necessary or cost prohibitive. Because instant tests are not as reliable as laboratory based testing, any positive drug result should be confirmed through laboratory testing. Since detection times vary with urine testing, it is important to know what those approximate detection times are so that testing can coincide with suspected use times.

Instant urine testing requires that the donor provide approximately 45 milliliters of urine (about 1½ ounces), so individuals who are undergoing certain medical treatments or problems may not be able to test if the treatments or problems affect their ability to provide a valid urine specimen.

Instant urine drug testing cannot be used in legal proceedings.

Information for Purchasers

Prior to purchasing

Make sure you understand what an instant test is and isn't.

Before ordering an instant test kit, it is important that you understand what an instant test kit is and what an instant test kit isn't.


An instant test kit can be useful in many situations, but there are many limitations and items that you should be aware of before purchasing and using your testing kit.


Some of the limitations and items to be aware of include:


  • Since testing kits are physical items, they are subject to damage from water, extreme temperatures and aging.
  • If you are an employer and intend to use instant test kits for hiring or periodic testing purposes, it is important to understand your state's laws. Some states may specifically prohibit their use, others may require additional testing if a result is non-negative.
  • Instant test kits cannot provide you with an accurate "positive" result. Results are either negative or are non-negative, sometimes called a presumptive positive. Non-negative results should be confirmed with a laboratory test to ensure that the result was not because of an ingested food or over-the-counter medicine.
  • If an instant test is performed at home and is non-negative, the donor should immediately proceed to a clinic for a second specimen collection to confirm the result. If the instant test was performed in a clinical setting, the laboratory confirmation testing is available without a second specimen being collected.
  • Instant test kits have a shelf life and should not be used after their expiration date.
  • Instant test results can be used in legal proceedings
  • Due to the nature of instant tests, we are not able to offer warranties, guarantees or accept returns for exchanges or refunds for kits that are sold. All sales of instant kits are final. This does not apply to the kits we use for collections in our clinic.


If you have questions about the limitations of the testing kits, or are unsure if instant kits will work in your situation, please let us know this when ordering your kits.

Discussing your results with the doctor

Confirmation tests include a review of the test by a medical review officer.

Confirmation tests include a review of the test my a medical review officer (MRO) who may contact you to discuss your result before releasing it. 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 there are any questions about your test, 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 confirmation results

Instant tests that were collected in our clinic and sent for laboratory confirmation will typically be available in 3 days.

Specimens sent for confirmation are typically available 3 to 7 days after the specimen is collected. A mailed test result is provided and typically arrive in the mail 8 to 15 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 8 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 collection.


For help interpreting your confirmation 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?

Instant testing can be confusing and frustrating. We understand.

Normally urine drug testing is performed in a laboratory and all that the donor needs to do is provide a sample and wait for a result that says "positive" or "negative". Instant tests are different. Reading and understanding the instructions for an instant urine test can be confusing when you are already worried about the reasons behind the test being performed. Simply knowing that you need to take a test, or that you need to have someone test, can be stressful before you even order your kit. After collecting the sample you have the added anxiety of reading the test result and worrying if you are reading it correctly. We understand that you will have questions and concerns like these. We want you to know that we will be here each step of the way to help you, even after the kit is picked up or shipped. If you have any questions about the instructions, help reading your results or would like information on where substance abuse treatment can be obtained, please give us a call, we are here to help.
