The expected diagnostic yield as a function of the prevalence of Gram-positive bacteria for a fixed population of 1,000 positive blood cultures for (A) Sepsityper, (B) BioFire BCID2, and (C) Fast Lipid Analysis Technique (FLAT MS). Expected diagnostic yield displays the distribution of accurately identified Gram-positive bacteria (red), accurately identified Gram-negative bacteria (gray), unidentified Gram-positive bacteria (gold), and unidentified Gram-negative bacteria (blue).
