When diagnosing pneumonia in cells stimulated with LPS, a cutoff of 3.59% change in IFN-γ produced sensitivity, specificity, and accuracy of 80% (89.1% AUC), and a cutoff of 2.08% change in IL-12 produced sensitivity of 80%, specificity of 78.9%, and accuracy of 79.4% (85.2% AUC). The gene discussed is IFNG; the disease is pneumonia.
