Interestingly, CRP, as a widely used infection marker, presented with a low predictive capacity (ROC-AUC: 0.569, 95%CI: 0.512–0.626), while several liver-related blood variables were significantly elevated in bacteraemic SIRS patients (e.g. bilirubin, gamma-glutamyl transpeptidase (γ-GT) or alanine transaminase (ALAT), see Table 2). The gene discussed is GPT; the disease is systemic inflammatory response syndrome.
