All three are closely related to severe pneumonia and are common indicators in blood routine. Especially, the combined detection of lymphocyte count, CRP, and platelets is often more valuable than individual indicators. This article provides a brief review of the relationship between lymphocyte count, CRP, platelet count, and their combined detection with severe pneumonia, in order to provide more evidence for early identification of severe pneumonia.展开更多
