The eight free calculators are validated clinical scoring tools that run right in the browser: BMI with WHO classification, eGFR by the CKD-EPI 2021 equation, CHA2DS2-VASc for stroke risk in atrial fibrillation, CURB-65 for pneumonia severity, the Wells Score for pulmonary embolism, the Glasgow Coma Scale, SOFA, and the PHQ-9 depression screen.

There is no sign-up and no paywall on these. Enter the values and get the score, with the classification and interpretation alongside it.

The free abbreviation glossary carries the glossary entries, each expanded and given a short line of clinical context, filterable by specialty and searchable instantly. ABG, ACS, GCS, SOFA, and other common terms are all there.

These free tools are a genuine slice of the wider MedNext platform, which adds a full formulary, the ECG and X-ray atlases, clinical calculators, differential diagnosis, and a clinical image library.
