The FilmArray Gastrointestinal (FA-GI) Panel is a qualitative multiplexed nucleic acid-based in vitro diagnostic test intended for use with FilmArray systems. The FA-GI Panel is capable of the simultaneous detection and identification of nucleic acids from multiple bacteria, viruses, and parasites directly from stool samples in Cary Blair transport media obtained from individuals with signs and/or symptoms of gastrointestinal infection.
Testing includes- Bacteria: Camplyobacter (C.jejuni/C.coli/C.upsaliensis), Clostridium difficile (toxinA/B), Plesiomonas shigelloides, Salmonella, Vibrio (V. parahaemolyticus/V. vulnificus/v. cholerae), Vibro cholerae, Yersinia enterocolitica. Diarrheagenic E.Coli/Shigella: Enteroaggregatvie E.coli (EAEC), EnteropathogenicE.coli (EPEC), Enterotoxigenic E.coil (ETEC) it/st, Shiga-like toxin-producing E.coli (STEC) stx1/stx2, E.coli 0157, Shigella/Enteroinvasive E.coli (EIEC). Viruses: Adenovirus F 40/41, Astrovirus, Norovirus GI/GII, Rotavirus A, Sapovirus (Genogroups I, II, III, and IV). Parasites: Cryptosporidium, Cyclospora cayetanensis, Entamoeba histolytica, Giardia lamblia .
Result Reporting: A result for all reported analytes will be provided as Detected or Not Detected. Positive results for Plesiomonas, Vibrio, Salmonella/Shigella, and Yersinia will result in a culture and susceptibilities if the bacterium is recovered. Clostridium difficile will not be reported on patients <3 years of age, because asymptomatic carriage in this age group is common. Enteropathogenic E. coli (EPEC) and Enteroaggregative E.coli (EAEC) are part of the manufacturer?s panel, but will not be reported due to high detection rates in pediatric patients, unclear significance, and concern for misattribution of disease associate with asymptomatic carriage.
Additional Stool Testing Conventional stool testing should not be ordered in addition to the GI Panel. If a stool culture, O&P exam, or parasite/viral antigen tests are ordered with the GI FilmArray panel, the panel test will be performed and not the individual assays.
Stool collected in diaper is acceptable following NCH Helping Hands-Stool collection guidelines.?Stool collected in diaper must be placed in appropriate container/media prior to sending to lab.
Stool in contact with urine will not be processed but rejected.
