What does it mean if a baby's blood test shows elevated levels?

The most common cause of elevated blood counts in infants is infection, such as pneumonia, bronchitis, or bacterial enteritis. Certain other conditions, like leukemia and pernicious anemia, can also lead to high blood counts. Symptoms of elevated blood counts in infants may include headache, nausea, vomiting, and fever. High blood counts can seriously affect a baby's health, so parents should seek immediate medical attention if they discover their baby has elevated levels, to ensure early diagnosis and treatment. After seeing a doctor, parents should also pay attention to the baby's nutrition and hygiene, striving to maintain the child's overall health.
