FBL and Sepsis: For example, for an 8-month-old infant with a respiratory rate of 55 breaths/min (0 points), a temperature of 39°C (19.7 points), immature granulocyte percentage of 3.8% (23.75 points), a procalcitonin (PCT) level of 6 ng/ml (28.6 points), a platelet count (PLT) of 105*109/L (0 points), a fibrinogen (Fib) level of 90 mg/dl (27.5 points), and a lactate level of 6 mmol/L (12 points), the calculated total score would be 111.5, corresponding to a predicted sepsis risk of 0.84 (Figure 3).
