Frequently asked questions
Lab-Score: What does this calculator compute?
Lab-Score (Lacour 2008) for children aged 7 days to 36 months with fever without an identifiable source: procalcitonin (0, 2 or 4 points), CRP (0, 2 or 4 points) and urine dipstick (1 point for leukocyte esterase or nitrite). Sum 0 to 9; from 3 points a serious bacterial infection is more likely (sensitivity 85–94 %, specificity 78–87 %).
