70%

of surveyed clinicians wait at least 4 days for lab results

Clinicians often make dosing decisions without knowing whether a patient is a slow or fast metabolizer, increasing the risk of over- or underdosing. As a result, they are dosing in the dark, which can lead to poor treatment outcomes for patients.
