How much blood can a newborn lose?

It is important to note that any amount of blood loss in a newborn should be taken seriously and should be evaluated by a healthcare professional. The appropriate amount of blood loss will vary depending on the individual newborn's weight, age, and overall health. In general, a newborn can lose up to 1% of their total blood volume before showing signs of anemia, which is equivalent to approximately 10 milliliters of blood for a full-term newborn. However, even small amounts of blood loss can be significant in premature or low birth weight infants. Therefore, it is always important to consult a healthcare professional if you are concerned about any bleeding or blood loss in a newborn.
