Total Protein
AgeConventional UnitsSI Units (Conventional Units × 10)
Newborn–5 d3.8–6.2 g/dL38–62 g/L
1–3 yr5.9–7 g/dL59–70 g/L
4–6 yr5.9–7.8 g/dL59–78 g/L
7–9 yr6.2–8.1 g/dL62–81 g/L
10–19 yr6.3–8.6 g/dL63–86 g/L
Adult6–8 g/dL60–80 g/L
Values may be slightly decreased in older adults due to insufficient intake or the effects of medications and the presence of multiple chronic or acute diseases with or without muted symptoms.
