Intended use: bact/alert® fa plus culture bottles are used with bact/alert® microbial detection systems in qualitative procedures for recovery and detection of aerobic and facultative anaerobic (bacteria and yeast) from blood and other normally sterile body fluids.Issue description: a customer in argentina notified biomérieux of false positive bcid results associated with 3 samples tested in the bact/alert fa plus (plastic) 100 btls -ref.410851, lot 0004102408.Summary: bcid2: not provided but false positive for s.Marcescens.Sample: positive blood culture.The bact/alert bottle is a qualitative test, detecting the presence or absence of an organism.There is a possibility of the presence of nucleic acids from non-viable microorganisms in the media used in the bact/alert bottles.The presence of nucleic acids from non-viable microorganisms, alone, will not cause the bact/alert bottle to flag as positive for growth as the organism is not viable and cannot grow in the bottle.The physician should use all information available on the patient to interpret the biofire® filmarray® bcid2 panel results accordingly.The presence of contaminating nucleic acid from non-viable microorganisms in the media, not from the patient sample, is a possibility that must be considered when interpreting the biofire® filmarray® bcid2 panel results.
