Genetic Testing
Qb Testing for ADHD
Many people suffer with intolerable side effects from psychiatric medications and lack of efficacy after numerous trials. Genetic testing can identify pharmacogenetic markers and shed light on whether a particular medication will be effective or whether there is a higher risk of adverse effects based on your genetic profile.
FDA cleared for use in patients aged 6-60. Clinicians around the world still solely rely on subjective data to diagnose ADHD in patients, which can provide conflicting information.
By using standardized, objective ADHD data with QbCheck, we can reduce the effects of subjectivity and get a data-driven understanding of core ADHD symptoms with easy-to-read, instantly generated reports. This, alongside our thorough ADHD assessment, will allow us to serve our patients better and improve outcomes.
Psychopharmacology
Medication management includes continual assessment of medication effectiveness, symptom management, and side effects. Patients will be educated about how medications work and what to expect when taking medication, including potential side effects. Medications can provide much needed relief and improve a person's quality of life.
​
Practice Philosophy
We believe in treating each patient as unique and not using a "one size fits all" model. We talk with patients and work with them to identify stressors and ways to cope more effectively in their daily lives. Our patients actively participate in their care; therefore, we use a collaborative approach to determine the best treatment options. It is an honor to assist our patients to reach their full potential and live their best possible lives. We are 100% dedicated to helping our patients become the best versions of themselves and achieve all they can in life.
ADHD Evaluation for Children and Adults Using Qb Testing
Ages 6-60 years old
What is QbTest Telehealth powered by QbCheck? QbTest Telehealth is an FDA-cleared test measuring all three core symptom domains; hyperactivity, impulsivity, and inattention. It is used when evaluating ADHD symptoms and measuring response to ADHD treatment. Both the in-clinic (QbTest) and remote version (QbCheck) involve 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) performance with data from other people of the same sex and age.
