  • openFDA Device Enforcement 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.
  • openFDA Device Recall 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.

App-derived interpretation

Unknown reason.no_named_rule · v1.0.0
A customer reported a problem with the reagent and calibrator. Randox Laboratories carried out an investigation and confirmed the issue. The complaint is pertaining to atypical calibration curves that can results in non-numerical results. This affects Siemens Atellica CH analysers only. Customer have reported an atypical calibration curve that results in the values around the low QC range to produce a non-numerical result. It appears to be related to the bottle values of the calibrator producing a curve shape that is too linear for the logitlog calculation to calculate. This issue can only be identified in the Atellica graphical view of the calibration. In most of the cases when this has occurred, it is picked up by the QC generating a Math Error, however, there are reports of QC shifts after calibration without the Math Error flagged that may be related to this issue. Results reported with STFR Level 1, with a concentration less than 1.7mg/L, using TF10159 and TF10161 can be underestimated by up to 30%. This issue has been reported with reagent lots 575475 and 562691, calibrator lots 537725 and 562696. No other complaints received.
