The service visit at the kaiser permanente regional lab was scheduled per capa (b)(4)within work order wo-00199891.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 (03838).Data review: per the verigene assay temperature tolerance (guard-band) study report (03768),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 03838, 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 +39.1c, within the range established in 03838.However; setpoint 2 had an adjusted temperature of +93.5c, 1.5c 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 cdf, 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.
