While performing tsb log verifications per fsa (b)(4) on verigene processor sp instrument (pn 10-0000-07r) s/n (b)(4), the fse noticed the incorrectly marked tsb log affixed to the back of the instrument.The fse saw that tsb (b)(4) for amp heater replacements was not completed but marked as completed on the log.The fse verified the accuracy of the tsb log per fsa (b)(4) and replaced the tsb log.The discrepancy was discovered by the fse during a tsb log verification check at (b)(4).Tech support changed risk assessment question 4 to 'yes' as a result of this found labeling issue.It should be noted a similar issue was found on (b)(6) 2021 and escalation case (b)(4) was opened to address this issue.Through investigation it was found that potentially 300+ verigene i sp's may have been incorrectly marked due to tsb (b)(4), tsb log installation for verigene sp technical service bulletin, not being executed properly.To mitigate the risk of incorrectly marked tsb logs in the field, fsa (b)(4), verigene i processor sp tsb clarification field service advisory, was released for field use on (b)(6) 2021.This fsa was created to prevent any confusion around tsb log installation and provides detailed instructions on how to verify sp services performed on the instrument.Other corrective actions relating to the installation and accuracy of tsb stickers will be captured in (b)(4).Within that same work order ((b)(4)), the hyb heater required recalibration after failing initial verification.During the site visit, the hybridization (hyb) heater required recalibration due to failing initial verification at setpoints 1 and 2.Field quality updated risk assessment question 2 to 'yes' since the setpoint temperatures failed outside the accepted limits established by the verigene i assay temperature tolerance guard band risk report ((b)(4)).Data review per the verigene assay temperature tolerance (guard-band) study report ((b)(4)),the study evaluated assay performance of verigene® rp flex, ep, cdf, bc-gp and bc-gn assays at varying critical temperature parameters and established a functional range of temperature for assay tolerance above and below the nominal set points.It was determined within (b)(4), that the hyb heater has an upper and lower tolerance of +/-2 degree celsius from the setpoint temperature 1 (38.5c) and setpoint 2 (90.0c).In reviewing the attached naplogs, setpoint 1 for the hyb heater had an adjusted temperature of +39.3c, within the range established in 03838.However, setpoint 2 had an adjusted temperature of +92.4c, 0.4c higher than the acceptable range per 03838.Due the finding, risk assessment question 2 was updated to 'yes'.Site performance the customer site is currently running ep, bc-gp, and bc-gn verigene assays.The hyb heater verification failure can potentially impact assay performance related to the bc-gn and bc-gp assay per 03838.Within an 18-month timeframe from the verification failure, the customer site has not reported any patient sample false results on either assay.Conclusion the customer site reported no false results for the sp processor s/n (b)(4).There is no indication of this verification failure resulting in an adverse effect to patient results.
