The Role of Procalcitonin in Inflammatory Markers

In terms of inflammatory marker, I think procalcitonin to me based on the literature is that has the best sort of ROC curve means it's the best balance of sensitivity and specificity. So I tend to value that one the most. But I think a lot of us have to reconcile our own risk tolerance when faced with a positive inflammatory marker and how we handle it. It's going to come down to our own sort of risk tolerance, the practice setting you're in, et cetera. We'll take all the exclusions aside, obviously of the child's ill appearing and that trumps everything.
