GNR Traffic Light PNA FISH is a multicolor, qualitative nucleic acid hybridization assay intended for the identification of Escherichia coli, and/or Klebsiella pneumoniae and/or Pseudomonas aeruginosa on smears from positive blood cultures containing Gramnegative rods observed on Gram stain.

Subculturing of positive blood cultures is necessary to recover organisms for susceptibility testing and/or differentiation of mixed growth.

The GNR Traffic Light PNA FISH assay is indicated for use as an aid in the diagnosis of E. coli, and/or K, pneumoniae, and/or P. aeruginosa bacteremia.
