Identification of Gram-positive bacteria using BC-GP assay

Signal intensities of BC-GP array for 105 speimens The Verigene Gram-Positive Blood Culture (BC-GP) nucleic acid assay is an automated microarray-based test, which can detect 12 Gram-positive bacterial genes and 3 resistance determinants using blood culture broths. We investigated signal intensities of microarray spots, and reclassified undetermined results where the automated system failed and various errors were called in blood culture specimens and spiked samples. Signal intensity analysis of BC-GP assay. SAMPLE_077 [Blood culture, Escherichia coli, Gram-negative, BacTALERT, Supernatant, Peripheral blood] had no signal data in the array raw data. Thus, SAMPLE_077 is not represented in this Series.
