Study Notes
Hematological Parameters in Newborns
- The average hematocrit level in a newborn is around 50-60%.
- The average hemoglobin level in a newborn is around 17-22 g/dL.
- The approximate blood volume per kilogram of body weight in a newborn is around 80-90 mL/kg.
- The approximate range of white blood cell count at birth is 9,000-30,000 cells/μL.
- At the end of the 3rd month, the hemoglobin level decreases significantly, often by 2-3 g/dL.
- The approximate iron level at birth in a newborn is around 150-200 µg/dL.
- Delayed cord clamping leads to an increase in erythrocyte count at birth.
- A capillary heel stick in a newborn may reveal blood glucose levels, bilirubin levels, and hematocrit.
