Calculator available
This page has an active local calculator in PedsCore. Entered values are processed in the browser, with references, limits and interpretation shown alongside the result.
Clinical use
This PedsCore page brings together clinical information, implementation status and available evidence for Ballard / New Ballard. It is intended for Newborns with uncertain gestational age. The tool belongs to Neonatology and should be interpreted in the appropriate clinical context.
Interpretation and validation
Independent numeric implementation of the New Ballard Score. PedsCore does not reproduce protected illustrations, drawings, or descriptive wording from the original form: users consult an authorized external visual reference and enter the numerical scores. Gestational-age conversion follows the official score grid and Ballard's completed-week rule. If MSD later authorizes reproduction of its sheet, it could be integrated without changing the calculation logic.
PedsCore does not replace clinical judgement. Scores, rules and calculators are presented with evidence traceability and a visible implementation status.
Clinical review and maintenance
Implementation review and independent clinical review are shown separately. PedsCore does not attribute named reviewers or external endorsement without a public record supporting the claim. The repository preserves source, change and test history.
Editorial transparency
This page is part of an open-source project. Evidence level, implementation status, validation notes and sources are shown explicitly. It currently contains 1 catalog reference. Content and calculation changes are reviewed through the public repository, automated tests and version traceability.
The absence of an active calculator is not a clinical recommendation: some tools remain reference-only while source, licensing, exact variant or validation still require review.
Each page lets you verify what is being assessed, which population the tool describes, whether local calculation is available, which limitations remain open and which references support implementation. This context matters when different publications, versions or adaptations share a similar name but are not interchangeable.
