Serum S100B Levels Can Predict Computed Tomography Findings in Paediatric Patients with Mild Head Injury

S100B levels by age group.

Serum S100B; values (μg L^−1)	Age group (years)
	<5	5–9	10+
	13	29	38
Mean	0.308	0.338	0.476
SD	0.254	0.253	0.329
Min	0.127	0.121	0.121
Max	0.923	1.230	1.532
value

Although serum S100B levels increased with age, the Kruskal–Wallis test did not identify statistically significant differences among the groups with median S100B levels of 0.308 μg L⁻¹ (SD ± 0.254 μg L⁻¹), 0.338 μg L⁻¹ (SD ± 0.253 μg L⁻¹), and 0.476 μg L⁻¹ (SD ± 0.329 μg L⁻¹) in children <5 years old, 5–9 years old, and 10+ years old, respectively.
