Report-date coverage
June 20, 2012–July 08, 2026
Known gap: openFDA describes 2004-present coverage, but the current export has no report-date records in this interval.

event_date_initiated coverage
June 01, 1997–June 30, 2026
Enforcement coverage uses report dates; product initiation dates can precede those bounds. Device-enrichment coverage uses FDA event_date_initiated.
Product dates, classifications, firms, and source wording remain attached to their individual rows.
Opening this dossier never hides products that did not match a prior timeline filter.

The Enzyme 2 Calibrator is an in vitro diagnostic product for the calibration of Alanine Aminotransferase (ALTI and ALTI) and Aspartate Aminotransferase (AST) methods on the Dimension Vista System. For prescription use only.
Complaints of positive shift of patient and QC results when the ALTI assay is calibrated with the Dimension Vista Enzyme 2 calibrator. Internal investigation has confirmed that patient samples and QC material demonstrate a shift of up to 10% in comparison to results obtained using earlier calibrator lots.
These labels are deterministic app interpretations, not FDA categories.
Official device-enrichment evidence · Unknown
An exact joined enrichment record exists, but none supplies supported root-cause wording. This is not an FDA finding of an unknown cause.
