Inflammatory markers (IMs)—C-reactive protein (CRP), procalcitonin (PCAL), and erythrocyte sedimentation rate (ESR)—are commonly used tests that are often ordered concurrently for the evaluation of infection, despite evidence suggesting that the simultaneous use of multiple IMs increases costs without improving patient care.4 Compared with CRP and ESR, PCAL is relatively new, and its exact utility in pediatrics is still being explored. Here, CRP is linked to infection.
