Normal Values of Serum IgE Levels in Children (in IU/mL)

 Serum IgE levels in children can vary widely depending on age, genetic, and environmental factors. Here are the generally accepted normal ranges of serum IgE levels for different age groups in IU/mL:

1. Infants (0-12 months):

   • Normal Range: 0-15 IU/mL

2. Toddlers (1-2 years):

   • Normal Range: 0-30 IU/mL

3. Preschoolers (3-5 years):

   • Normal Range: 0-50 IU/mL

4. School-age Children (6-9 years):

   • Normal Range: 0-100 IU/mL

5. Adolescents (10-15 years):

   • Normal Range: 0-200 IU/mL
