TREM1 and Neonatal sepsis: The accurate diagnosis and prognosis of neonatal sepsis remains a scientific challenge and many potentially useful early biomarkers have been explored during recent years [7], including procalcitonin (Pct) [8,9,10,11,12], interleukin (IL)-6 and IL-8 [13,14,15,16], presepsin [17,18], serum amyloid A (SAA) [19], soluble triggering receptor expressed on myeloid cell-1 (TREM-1] [20], and many others [6,7].
