CRP and radiation injury: Interestingly, the key biomarkers found included aspartate aminotransferase, LDH, urea, Flt3-ligand, iron, creatine kinase, absolute neutrophil count and neutrophil-to-lymphocyte ratio for the early period after the radiation exposure, C-reactive protein, and Flt3-ligand, platelet count, iron, hemoglobin, monocyte count, absolute neutrophil count and neutrophil-to-lymphocyte ratio for the acute radiation syndrome phase.
