Clinical reference tools for practitioners and patients

Zdrovia's clinical tools translate peer-reviewed literature and published assessment instruments into interactive references that help practitioners and patients make informed decisions. Each one is sourced from specific studies, FDA-approved labelling, established guidelines, or the original published instrument, with citations on every page. Where an instrument is copyrighted, we explain how to interpret a score and point you to the official source rather than reproducing it.

These tools are for educational and reference purposes only. They are not a substitute for a qualified practitioner's assessment, and no screening score is a diagnosis. Always consult a licensed healthcare provider before undergoing any treatment or acting on a result.
