What is the lifespan of neonatal red blood cells?

The lifespan of neonatal red blood cells generally ranges from 80 to 100 days. This is significantly longer than the lifespan of red blood cells in adults, which typically lasts about 120 days. Neonatal red blood cells have a shorter lifespan compared to adult cells due to several factors, including their size, composition, and the environment in which they develop. As newborns transition from fetal to postnatal life, their red blood cells adapt to different levels of oxygen and nutrient supply, which influences their survival and functionality. Understanding the lifespan of neonatal red blood cells is crucial for healthcare providers in managing conditions such as anemia in newborns, as it helps inform treatment decisions regarding blood transfusions and monitoring of hemoglobin levels.
