As Table 2 shows, the accuracy of SAA measurements in distinguishing which patients went on to develop an infection and which did not reached values of 73.2% (cut-off: 14.2 μg/mL) and 77.1% (cut-off: 8.8 μg/mL) at hospital admission and 1 day after, respectively. The gene discussed is SAA1; the disease is infection.
