Frequently Asked Questions

Why Use Instant Tests?

Rapid diagnostic tests, or “instant” testing, is a cost effective and accurate way to get quick, preliminary results in a range of point-of-care settings. Whether it be for drugs of abuse, infectious disease, or fertility and wellness testing, DrugSure™ rapid diagnostic test devices can deliver quick and accurate results in minutes.

Do I need Lab Testing Services?

Rapid diagnostic testing DOES NOT eliminate the need for lab testing services BUT they do minimize it. There will always be certain situations where a confirmatory lab test is a necessary step after receiving a preliminary test result. NTS has an expansive lab network offering the services you will need when an instant test just is not enough.

What is the detection window in Urine tests Compared to Saliva tests?

The window of detection is an extreamely important aspect to consider when performing instant diagnostic testing epecially when testing for drugs of abuse. Urine typically will have a longer window of detetion than saliva ranging from a few days to weeks to even up to a month with certain substances like THC, but there are many factors that play a role in determining a substances’ window of detection when using a urine specimen. The age, weight, and frequency and volume of consumption of the patient as well as the substance itself. Salvia specimens, while having accurate detection, will typically only have a window of detection of 24-48 hours after last use.

Do I need to use CLIA-Waived Tests?

Depending on the type of program, you may need to use CLIA-Waived test devices. CLIA regulatory requirements vary according to the kind of test(s) each laboratory conducts. Tests are categorized as waived, moderate complexity or high complexity. With respect to CLIA applicability, the CLIA regulations do not differentiate between facilities performing provider-ordered testing and those performing non-provider-ordered testing. All facilities that meet the definition of a “laboratory” under the CLIA statute and regulations must obtain an appropriate CLIA certificate prior to conducting patient testing. Whether a test service is billed to Medicare has no bearing on CLIA applicability. Please review our CLIA information here or call us to chat with an expert.

What Does FUO Mean?

FUO stands for Forensic Use Only and are testing devices that have not been waived by CLIA or cleared by the FDA. FUO tests can be used in criminal justice and law enforcement settings. Contact one of our experts for more information.

Can I choose which substances I want to test for?

Yes, we do offer customized testing options. Speak with a representative to get your customized testing device and hand pick the substances that best fit your testing program. Lead times may vary due to availability and production.
