Various diagnostic tools have been extensively studied over many years for EOS like WBC, BANDS, ANC, immature to total neutrophil ratio, CRP, interleukin six, procalcitonin.
Immature to total neutrophil ratio (I/T ratio) calculated by the following formula:
C-Reactive protein, Immature to total Neutrophil Ratio and Micro ESR in early diagnosis of Neonatal Sepsis.
Immature to total neutrophil ratio and absolute neutrophil counts have higher specificity, but are often normal early in the course of infection.
This study aim to estimate the level of procalcitonin in neonatal sepsis and to compare the sensitivity and specificity of procalcitonin with that of WBC count, immature to total neutrophil ratio, CRP level and blood cultures.
