The service visit at katherine (b)(6) hospital.Was scheduled per capa-21-014 within work order wo-00199948.During the site visit, the elution 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)).Per the verigene assay temperature tolerance (guard-band) study report ((b)(4)), the study evaluated the 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 elution heater has a lower tolerance of -4degree celsius and an upper tolerance of greater than or equal to 5degree from the setpoint temperature 1 (75.0c) and setpoint 2 (85.0c).In reviewing the attached naplogs, setpoint 1 for the elution heater had an adjusted temperature of +86.1c and setpoint 2 had an adjusted temperature of +97.9c; both higher than the acceptable range per (b)(4).Due the finding, risk assessment question 2 was updated to 'yes'.The customer site is currently running bc-gp, bc-gn, and ep verigene assays.The elution heater verification failure can potentially impact assay performance for all three assays ran at the customer site per (b)(4).Within an 18-month timeframe from the verification failure, the customer site has not reported any patient sample false results on either assay.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.
