What to Include

To help us address your inquiry as efficiently as possible, please include the following details:

• A clear subject line summarizing your question or concern
• The specific tool or page you are referencing (include the URL if possible)
• Your role or specialty (e.g., obstetrician, sonographer, researcher)
• Any relevant input values or results if you are reporting a calculation concern

Reporting Issues

If you suspect an error in a calculation, reference value, or clinical recommendation, please contact us immediately so we can investigate. Include the specific inputs used, the result displayed, and the expected result based on your independent calculation or reference source.

For urgent clinical matters, always consult primary medical literature or institutional protocols rather than relying solely on this or any other digital tool.

We are committed to continuous improvement. If you have suggestions for additional tools, reference data, or features that would support your clinical practice, we would like to hear from you.

Clinicians and researchers interested in contributing evidence reviews or validation data are encouraged to reach out. Please see our About Us page for more on our methodology and standards.
