What is the general range for normal neonatal WBC counts?

The normal range for neonatal white blood cell (WBC) counts is generally considered to be 5,000 to 30,000 cells per microliter (µL) of blood. This range is significantly higher than that of older children and adults, primarily due to the unique physiological state and the need for an elevated immune response in neonates.

In the early days of life, neonates have an immature immune system, and having a higher WBC count can serve as a protective mechanism against infections. This elevated range decreases as the infant matures. Understanding this range is crucial for neonatal nurses, as abnormalities in WBC counts can indicate infection, stress, or blood-related disorders.

The other ranges presented do not accurately reflect the normative data for neonatal WBC counts.
