Event or Problem Description
Intended use: the reveal ast system is an in-vitro diagnostic (ivd) automated system for antimicrobial susceptibility testing of organisms direct from positive blood culture.The reveal ast assays are indicated for susceptibility testing of specific pathogenic bacteria commonly associated with or causing bacteremia as well as bacterial isolates from other specimen types.Results are intended to be used in conjunction with gram stain, organism identification and other clinical laboratory findings.Issue description: a customer in spain notified biomérieux of discordant results for antibiotics : ceftazidime -potential false susceptible results in association with vitek® reveal¿ sensor panel (20 tests) (ref.900-00002, lot.101724gwa).Customer reported that when comparing the results obtained with vitek reveal and microdilution the customer reported discordant results.Results are summarized below: (b)(4): the lot numbers are 101724gwa for the sensor and (b)(6) 2025.Antibiotic ceftazidime reported mic 0.5 s while it was resistant with diffusion disk.Under the suspicion that the vitek reveal results were not correct, they were not reported and therefore did not have any effect on the treatment of the patient.Biomérieux local customer service indicated that after taking a look to the troubleshooting files, some leak graphs seem to look abnormal, which could indicate leakage between wells.This has been communicated to the customer.At the time of the global assessment, there is no indication or report from the customer that this event led to any adverse event related to any patient's state of health.
