FDA Mock Deficiency Review - eSTAR, 510(k) & De Novo

Before FDA finds the gaps, we do.

Panabistics reviews your submission package the way a skeptical FDA reviewer may approach it, identifying likely deficiencies, weak rationales, inconsistent evidence, and missing documentation before you submit.

Expert-led, reviewer-style regulatory consulting, not a generic checklist.

Umbrella Service

Full eSTAR Mock Deficiency Review

A completed eSTAR is not always a submission-ready package. The Full eSTAR Mock Deficiency Review is a reviewer-oriented challenge of a substantially complete FDA submission package. Panabistics assesses whether the applicable evidence areas are complete, credible, traceable, and internally consistent before the package is submitted to FDA.

The review is tailored to the device type, submission pathway, technology, claims, and available documentation. Depending on the device, the review may include cybersecurity, software documentation, human factors and usability, risk management, labeling, bench and performance evidence, and clinical evidence.

Important: Not every review module applies to every device. The Full eSTAR review is scoped based on the applicable FDA requirements and the evidence package provided by the sponsor.

What This Service Is Not

This service does not replace FDA review, required testing or validation, legal advice, or the sponsor’s responsibility for the completeness and accuracy of the submission content. It is an independent regulatory and submission-readiness review designed to identify likely FDA review concerns before submission. Panabistics does not represent FDA and does not guarantee clearance or approval.
