Not Medical Advice
The information, tools, calculators, and content provided on ACR Calculator (the "Site") are designed strictly for educational and informational purposes only. The Site is not intended to provide, and should not be relied upon for, medical advice, professional diagnosis, opinion, or treatment.
Never disregard professional medical advice or delay in seeking it because of something you have read or calculated on this Site.
Always Consult a Qualified Healthcare Provider
If you have any concerns about your health, test results, or a specific medical condition, you should always consult with a licensed physician or other qualified healthcare provider. The results generated by our calculators are mathematical outputs based on standard formulas. They do not take into account your complete medical history, physical examination findings, other laboratory parameters, or personal health context.
Limitations of Online Medical Calculators
While we strive to ensure that our calculators are programmed accurately based on current, peer-reviewed clinical guidelines, users must understand the inherent limitations of online medical tools:
- Absence of Clinical Context: A calculated number (such as eGFR or BMI) is only one piece of a clinical puzzle. Without professional interpretation in the context of your overall health, these numbers can be misleading.
- Variability in Formulas: Medical formulas often have different versions or are updated as research evolves. While we aim to use the most current standard equations (e.g., the CKD-EPI 2021 equation for eGFR), the specific formula used may not be the one preferred by your physician.
- Potential for Input Error: The accuracy of a calculator's output is entirely dependent on the accuracy of the data inputted by the user. Errors in unit conversion (e.g., mg/dL vs. µmol/L) or simple typos will result in incorrect outputs.
For Healthcare Professionals
If you are a healthcare professional, the tools provided on this Site are intended to support, not replace, your clinical judgment. While we make every effort to verify our algorithms, it is your responsibility to independently verify the calculated results and apply them appropriately to your patient's specific clinical scenario.
Medical Emergencies
If you think you may have a medical emergency, call your doctor, go to the nearest hospital emergency department, or call emergency services (such as 911 in the United States) immediately. Do not rely on electronic communications or this Site for immediate, urgent medical needs.
No Liability
