A deep dive into Qbtech's diagnostic ADHD test

In a previous interview with Contemporary Pediatrics, Perry Roy, MD, of Carolina Attention Specialists, Charlotte, North Carolina, explained how the object QbTest from Qbtech can add value to an ADHD diagnosis.¹

"Currently, most methodologies for diagnosing ADHD is based on history. This [tool] is not replacing a good, accurate history. Other tools that have commonly been used and are certainly used are rating scales, which are quite subjective," said Roy.¹

According to Qbtech, the ADHD QbTest is FDA-cleared to aid in diagnosis and treatment evaluation for individuals aged 6 to 60 years. Measuring the core ADHD symptoms of ADHD (activity, attention, and impulsivity), the QbTest takes approximately 15 to 20 minutes to complete, with results delivered in a visual report (Pictured right.

These results compare the patient's results to others in their respective age range and gender without ADHD.²

"To me, I think it adds confidence to the diagnosis," said Roy. "This test can also help us manage the medications, let us know we're on the right track with the medications, [and] help us dose-optimize the medication."

Roy added the general provider can learn how to use and incorporate the test for a diagnosis, or confirm to the provider the need to refer out.

When the test was cleared by the FDA in 2014, the federal agency in a 510(k) summary of safety letter stated, "QbTest results should be interpreted only by qualified professionals."^3,4

The QbTest's intended use to support the evaluation of treatment interventions of ADHD was based on 7 published clinical studies and a registry study that was designed to compare QbTest with clinically validated Rating Scales (RS) in the evaluation of treatment interventions.⁴
