TNF and Neonatal sepsis: Other markers of inflammation, such as serum amyloid A (SAA), interleukins (IL-6, IL-8, sIL-2 receptor), and tumor necrosis factor α (TNF-α), are addressed in several studies as “early warning biomarkers” of neonatal sepsis, especially if they are combined with CRP but are not routinely used in clinical practice [87,88,91,92].
