Mean Platelet Volume and Mean Platelet Volume/Platelet Count Ratio Are Predictors of Late-Onset Sepsis in Preterm Infants: A Case-Control Study.

Our aim was to assess mean platelet volume (MPV) and mean platelet volume to platelet count ratio (MPR) in the setting of late-onset sepsis (LOS) and their association with the type of bacteria causing LOS. The MPV and MPR levels were obtained at the onset of LOS and then assessed in intra/inter group analyses in preterm infants. Overall, 136 preterm infants were enrolled.
