Introduction
A routine blood test (CBC) in infants generally cannot determine whether a child has an allergic constitution.
During a CBC, it is possible to ascertain whether the infant has a bacterial or viral infection, and to measure hemoglobin levels—thereby helping to identify whether anemia is present.
Allergic reactions may manifest not only as hives on the skin surface but also with accompanying itching.
A routine blood test (complete blood count, CBC) in infants generally cannot determine whether a child has an allergic constitution.
During a routine blood test, doctors can assess whether the infant has a bacterial or viral infection and measure hemoglobin levels to determine if anemia is present. However, this test cannot identify whether the child has an allergic constitution. If the infant frequently exhibits allergic symptoms in daily life, it is advisable to visit a reputable hospital for allergen testing to confirm whether the child has an allergic constitution. Once specific allergens are identified, avoiding exposure to them in daily life can help prevent allergic reactions.
When an allergic reaction occurs, symptoms may not be limited to skin manifestations such as hives but may also include intense itching, leading to significant physical discomfort. In such cases, antiallergic medications should be taken under a physician’s guidance to alleviate symptoms; commonly used options include antihistamines and anti-itch medications.
