What is the average blood volume in a newborn?

The average blood volume in a newborn is approximately 335 mL. This volume can vary slightly based on the size and weight of the newborn, but the general reference for a healthy newborn is in this range.

Understanding the average blood volume is important for medical professionals, as it helps in assessing the newborn's overall health and potential conditions related to blood volume, such as anemia or overhydration. In clinical practice, knowing this average allows for more effective planning for interventions, such as blood transfusions if necessary, and can contribute to better outcomes in neonatal care.

The other volumes listed do not accurately reflect the average blood volume in a healthy newborn, as they are either too low or too high compared to established medical guidelines and research.
