Diagnostic accuracy of complete blood cell count and neutrophil-to-lymphocyte, lymphocyte-to-monocyte, and platelet-to-lymphocyte ratios for neonatal infection.

Background: Complete blood cell (CBC) counts and neutrophil-to-lymphocyte (NLR), lymphocyte-to-monocyte (LMR), and platelet-to-lymphocyte ratios (PLR) are simple measurements that are conducted as part of routine diagnostic procedures.

Objective: To determine the diagnostic importance, specificity, and sensitivity of these measurements for the diagnosis of neonatal infections and in discriminating between neonatal sepsis and various other infections.

Methods: We conducted a retrospective study of data from a consecutive series of 232 neonatal patients admitted to Yildirim Beyazit University Yenimahalle Training and Research Hospital in Ankara for 2 years from 2016 to 2018.

Effect of Phototherapy on Peripheral Blood Cells in Hyperbilirubinemic Newborns.

This study was conducted to determine the neutrophil/lymphocyte ratio, lymphocyte/monocyte ratio, platelet/lymphocyte ratio; and to evaluate the effect of phototherapy on the peripheral blood cells in newborns with indirect hyperbilirubinemia. A total of 180 newborns consisting of 119 hyperbilirubinemic newborns, who received phototherapy; and 61 healthy newborns were included in the study. A statistically significant difference was present only between the patient group and healthy newborn white blood cell values after phototherapy.
