Import your sensitivity report

Import all three report categories and validate the complete ingredient catalogue.

A validated import checks extraction completeness, not the medical validity of the report.
Matches reflect your report, not overall food safety. No reactivity recorded applies only to tested entries. Anything not covered stays clearly marked.

Before importing your report

ScanSync compares ingredient information with your report. It cannot diagnose allergies or confirm food safety. The report may not be medically validated, and extraction errors are possible.

Please review your imported classifications. Do not use ScanSync as your sole source of medical or food safety information.
