What cord blood value of a full-term newborn falls into the optimal range?

The optimal cord blood value for a full-term newborn that is identified in this question is a platelet count of 160,000/mm³. This value falls within the normal range for newborns, which typically is around 150,000 to 450,000/mm³. Maintaining a healthy platelet count is vital for proper blood clotting and overall health, especially in newborns, as they are at risk for various bleeding disorders in the early days of life.

In contrast, while hematocrit levels can vary, a hematocrit of 50% might be considered high and could indicate polycythemia if above the normal range, which is typically around 45-60% for newborns. A monocyte count of 5% might be within the expected range for adults, but newborns usually have a higher percentage of neutrophils, making this less optimal. Total iron-binding capacity (TIBC) levels are also individualized and tend to vary; a value of 200 mcg/dL is not specifically tied to the established optimal range for newborns and could indicate either iron deficiency or other hematologic conditions depending on the clinical context.

Thus, the platelet count of 160,000/mm³ represents a normal and healthy value,
