Quest Diagnostics knows that your needs can change and having more choices benefits you and your patients when monitoring for the presence of drugs. For those situations when urine collection is not practical, you now have an alternative — oral fluid.

Oral fluid testing

When looking for the presence of prescribed drugs or substances of misuse and urine drug testing is not possible or not practical due to the patient’s condition, alternative specimen collection may be needed. Oral fluid drug testing provides a great option.

Why use oral fluid testing?

Oral fluid collection is simple to do whether you choose your office or a Quest Diagnostics Patient Service Center.  Collections can be completed in minutes, enabling you to monitor the collection.

Easy sample collection with Oral-Eze®

  • The patented oral fluid collection device has a volume indicator window designed to take the guesswork out of sample collection.
  • Collection time typically takes about 5 minutes, reducing time in the office and improving patient convenience.

How does oral fluid compare to urine drug testing?

Because salivary glands are highly perfused, drug is transferred rapidly from blood to oral fluid.  Therefore, drugs tend to be detectable in oral fluid sooner than in urine, and become undetectable more rapidly as well.  However, most drugs remain detectable for 24-50 hours after ingestion.  The detection window varies with the drug, duration of use, drug dose, and individual metabolism, among other variables.
