CRP and Sepsis: Blood tests include white cell count (which may lag behind other markers), platelets (an unexpected drop is related to sepsis), the sending of sputum, stool, and wound specimens for culture sent to the relevant laboratory, and the use of sepsis markers, of which procalcitonin (PCT) and beta‐d‐glucan appear the most clinically relevant, since CRP and D‐dimers are almost universally abnormal in the acute post‐trauma period.
