Quick Answer: A QbTest is a computer-based evaluation that objectively measures attention, impulsivity, and activity level, the three core symptoms of ADHD. It uses motion tracking and performance data to compare results against a normative group, giving providers objective evidence to support a diagnosis.
If you’re preparing for an ADHD evaluation, you may have heard the term QbTest and wondered what it actually involves. This test isn’t a guessing game or a quick quiz. It’s a structured, FDA-cleared tool that measures how your brain and body respond during a sustained attention task.
This post breaks down what a QbTest measures, what to expect during testing, and how LÉVO uses this test data alongside a full clinical picture to reach an accurate diagnosis.
What Is a QbTest?
A QbTest is a 15- to 20-minute computer-based assessment that uses infrared motion tracking to monitor movement while a person completes a simple attention task on screen. It’s designed to add objective, measurable data to the ADHD evaluation process rather than relying on observation alone.
QbTest is used for children, teens, and adults who are being evaluated for ADHD, as well as those already diagnosed who want to track how treatment is working over time. It doesn’t replace clinical judgment. It supports it.
What Does a QbTest Measure?
QbTest results focus on three core areas tied directly to ADHD symptoms:
- Attention: How consistently a person stays focused on the task without drifting or missing targets
- Impulsivity: How often a person responds too quickly or inaccurately, pointing to difficulty with self-control
- Activity: How much physical movement occurs during the test, tracked through infrared sensors
Together, these three measurements create a fuller picture of how inattention, impulsivity, and hyperactivity show up in real time, not just how they’re described in conversation.
What to Expect During a QbTest
Before the test, a provider will explain the task and answer any questions, so there are no surprises once it begins. During the test, the person sits in front of a screen and responds to simple visual prompts using a handheld device.
The test itself takes about 15 to 20 minutes. Afterward, results are processed and compared against normative data, with no recovery time needed. For kids, the process is designed to feel approachable, almost like a simple video game task rather than a clinical exam.
How QbTest Results Are Measured and Used
QbTest results are compared against a normative group matched by age and sex, which helps providers understand what’s typical versus what stands out. The resulting report shows how far a person’s scores fall from that typical range across attention, impulsivity, and activity.
Providers don’t interpret this data in isolation. Scores are reviewed alongside developmental history, behavioral observations, and input from parents, teachers, or the individual themselves to build an accurate, whole-person understanding of symptoms.
What a QbTest Can’t Do on Its Own
A QbTest provides valuable objective data, but it can’t diagnose ADHD by itself. According to QbTech, the test’s manufacturer, the test has supported more than a million ADHD assessments worldwide, yet it’s always intended as one piece of a broader evaluation.
Conditions like anxiety, sleep issues, or learning differences can sometimes produce similar patterns on a test. That’s why results need context from a trained clinician who understands the full picture, not just the numbers on a screen.
How LÉVO Uses QbTest in ADHD Evaluations
At LÉVO, QbTest results are one part of a much larger evaluation. Our providers take the time to connect test data with your history, symptoms, and daily experience, rather than reducing your evaluation to a single score.
This whole-person approach means we look at biological, psychological, and social factors alongside test findings. The goal isn’t just a diagnosis. It’s a clear, personalized treatment plan built around how ADHD actually shows up in your life.
Frequently Asked Questions
Is the QbTest accurate for diagnosing ADHD?
A QbTest adds objective, measurable data to an ADHD evaluation, but it’s most accurate when combined with a full clinical assessment, not used as a standalone diagnostic tool.
Can I take a QbTest through telehealth?
QbTest requires in-person equipment to track movement and responses accurately, so it’s typically completed at a clinic rather than through a virtual appointment.
Can adults take the QbTest?
Yes. Adults can take the test as part of an ADHD evaluation, and many use it to better understand lifelong patterns of inattention, impulsivity, or restlessness.
How long does it take to get QbTest results?
Test results are typically processed quickly after the assessment, often within the same visit, so providers can begin discussing findings without a long wait.
