H.6.Investigation: customer reported a false positive result and a leakage defect.Bd was unable to reproduce customer experience with the bactec product.A false positive response was not observed when retention samples were tested.Satisfactory results were obtained from retention samples when visually inspected for any cap defect or leakage.Vacuum draw was performed with satisfactory results.Batch history records were reviewed, and all testing were within specification for product release.A complaint history review was conducted and only the current complaint was found relating to the incident lot number and the ¿as reported¿ defect code.Complaint is unconfirmed based on retention samples and batch history review results.Users are cautioned in the package insert under limitation of the procedure: ¿a gram-stained smear from culture medium may contain small number of non-viable organisms derived from media constituents, staining reagents, immersion oil, glass slide and specimens used for inoculation.There are many factors that can influence the false positive rate, including blood volume, blood cell counts, environmental factors, and media lot to lot variations.Product insert warnings and precautions sections states that prior to use, each vial should be examined for evidence of contamination such as cloudiness, bulging or depresses septum, or leakage.Vials showing evidence of contamination should not be used.Also prior to use, the user should examine the vial for evidence of damage or deterioration.Vials displaying turbidity, contamination, or discoloration (darkening) should not be used.On rare occasions, a vial may not be sealed sufficiently the contents of the vials may leak or spill, especially if the vial is inverted.If the vial has been inoculated, treat the leak or spill with caution, as pathogenic organism/agents may be present.To minimize the potential or leakage during inoculation of specimen into culture vials, use syringes with permanently attached needles or bd luer-lok tips.No correctives actions were required.A cross functional team continually monitors all product complaints for trends and determines if any additional actions are necessary beyond the current investigation process.
