Should a newborn with high white blood cell count in a complete blood count be retested?

Patient's question:

Newborn had a few small bleeding spots on the buttocks on the first day, and it was recommended to do a complete blood count. The results are as follows. Tomorrow, the baby will be discharged because the fetus is eating and drinking normally, not feverish, and sleeping normally in all aspects, so no further review was conducted. The hospital suggested a follow-up review. Is it necessary? Or should I come back for a check-up if there are any abnormalities in a few days?

Doctor's answer:

Generally speaking, newborns have high white blood cells and neutrophils due to the influence of their mothers. If the levels are not particularly high, there should be no problem. However, if a child has high white blood cells and other symptoms, it is necessary to receive anti-infection treatment, as elevated white blood cells and neutrophils are mainly indicative of bacterial infection. Children with mild bleeding may have lower platelet levels. In this case, parents should take their child for further review and pay attention to feeding. It is acceptable to monitor the child's temperature changes.
