Summary
This study established age-specific immunoglobulin E (IgE) reference values for children using the ImmunoCAP assay. These values aid in diagnosing elevated IgE levels, crucial for pediatric allergy and immunology assessments.
Area of Science:
- Pediatric Immunology
- Allergy Diagnostics
Context:
- Accurate immunoglobulin E (IgE) reference ranges are essential for diagnosing allergic diseases in children.
- Existing reference values may not fully capture age-specific variations in IgE levels.
Purpose:
- To determine age-specific serum IgE reference values in a cohort of 224 children.
- To provide a reliable basis for identifying pathological elevations of IgE in pediatric populations.
Summary:
- Serum samples from 224 children were analyzed using the ImmunoCAP fluorescence enzyme immunoassay.
- Established reference values range from <0.35 kU/L in cord blood to 34.6 kU/L in the 8-12 year age group.
- Specific ranges were defined for cord blood, and age intervals up to 16 years.
Impact:
- Facilitates accurate diagnosis of IgE-mediated disorders in children.
- Supports clinical decision-making in pediatric allergy and immunology.
- Provides updated, age-stratified reference data for laboratory and clinical use.
