Neonatal sepsis is a major cause of morbidities and mortalities mostly remarkable in the third world nations.We aimed to assess the value of simultaneous measurement of procalcitonin (PCT) and interleukin-6 (IL-6) in association with high sensitive- C reactive protein(hs-CRP) in prediction of early neonatal sepsis. This evidence concerns the gene CALCA and Neonatal sepsis.
