Differential diagnostic value of manual and automatic procedure.

Note: (95% Confidence interval calculated with binomial expansion).
(See Supplemental data). A.: comparison of identification values obtained after using Accuracy matrix for both SeptiFast methods and blood culture+identification using Vitek II system. (Test Characteristics: Sensitivity: how good the test is at detecting an microorganism, Specificity: how good the test is at identifying patients with negative values, Positive predictive value: how often a patient with a positive test in fact has the microorganism, Negative predictive value: how often a patient with a negative test in fact does not have the microorganism.) B: Agreement matrix using kappa, which corrects the proportion of agreement due to chance and C: volumes of sample used in different experiments as reference for the compartment analyzed.
