Hemoglobin normal level for a baby under age 1 year is less than the normal values for adults and lesser than 3-9 months hemoglobin level.
Platelets count for under 1 year baby still as high as 550 thousand cells per cubic milliliter.
Total leukocytic count in a 1 year baby’s CBC test still show increased values and differential count usually show increase in lymphocytes which called lymphocytosis, nevertheless, in such age, lymphocytosis should be with normal morphology to be considered as normal,
3-9 months baby’s WBCs count is 10,000 which is lesser than 9-12 months count which is 17,500.
