What is a QbTest?

QbTest is an FDA-cleared test measuring all 3 core symptom domains; hyperactivity, impulsivity, and inattention. QbTest is used when evaluating ADHD symptoms and measuring response to ADHD treatment. QbTest involves a 15 or 20-minute computer-based task that measures your (or your child’s) ability to maintain attention and impulse control. Meanwhile, an infrared camera tracks movements, and therefore activity, during the test. The results are based on a comparison of your (or your child’s).

How should I prepare for a QbTest?
