RBCGN
RAPID BLOOD CULTURE IDENTIFICATION (GRAM NEGATIVE) REFLEX TEST ONLY

Test Code RBCGN 
Test RAPID BLOOD CULTURE IDENTIFICATION (GRAM NEGATIVE) REFLEX TEST ONLY 
Methodology Verigene Multiplex Film Array 
Description To provide rapid identification of gram negative organisms growing in a blood culture, in advance of phenotypical identification and susceptibility testing.

PLEASE NOTE: THIS IS A REFLEX TEST ONLY 

Specimen Positive blood culture demonstrating gram negative organisms by Gram stain 
Reference Values "Detected" or "Not detected" for the analyzed targets.
Organisms included in assay: Acinetobacter spp.; Citrobacter spp.; Enterobacter spp.; Escherichieae spp.; Klebsiella oxytoca; Klebsiella pneumoniae; Proteus spp.; Pseudomonas aeruginosa.Resistance markers included in assay: CTX-M; KPC; NDM; OXA; VIM; IMP.

LIMITATIONS: The following results may have the indicated limitations:

+In mixed cultures containing gram-negative bacteria and other organisms, BC-GN may not identify all the detectable organisms in the specimen.
+There is a risk of false negative or false positive results due to sequence variants in the bacterial targets of the assay.
+ The assay detects the presence of the CTX-M, KPC, NDM, VIM, IMP and/or OXA gene(s) in a specimen, but does not determine which organism present in the specimen contains the gene.
+ BC-GN will not distinguish Escherichia coli from Shigella spp. Including S. dysenteriae, S. flexneri, S. boydii, and S. sonnei.
+ BC-GN will not detect OXA 51.
+ Serratia marcescens may yield a false negative result with BC-GN, as demonstrated during analytical and clinical study testing.
+ BC-GN may not yield an "OXA Detected" result when Acinetobacter spp. Are detected.

A trained health care professional should interpret assay results together with a patient's medical history, clinical signs and symptoms, and the results of other diagnostic tests.
