Pro-Calsatona and C-Reactive Protein for Pneumonia

There is a very good argument that both C-reactive protein and Pro-Calsatona are far and vastly superior to white count for determining distinguish between bacterial and virile illness. However, there is a reasonable cost to those labs and the receiver operator curve isn't stellar. So I think they're adjunctively perhaps helpful in a minority of cases. For the majority of patients, there's probably no role for that because the majority of these kids are going to be just fine.
