The neutrophil/lymphocyte ratio is a better addition to C-reactive protein than CD64 index as a marker for infection in COPD

Abstract

Elevated NLR can be used as a marker similar to CRP, and RDW, in the determination of increased inflammation in acutely exacerbated COPD. NLR could be beneficial for the early detection of potential acute exacerbations in patients with COPD who have normal levels of traditional markers; CD64 was higher but did not reach statistical significance. MPV was not helpful.
