IgE in serum
Reference interval:
1) 3-423 IU/mL, age > 17 (median 40 IU/mL), 0-158 IU/mL (VA)
2) 1% of maternal value at term
3) 1.1-10.2 IU/mL, age = 1 year
4) 2.4-34.8 IU/mL. age = 4 years
5) 0.3-215 IU/mL, age = 10 years (mean 24 IU/mL)
Increases:
1) parasitic infections
2) allergic bronchopulmonary aspergillosis
3) pharmaceutical agents: especially gold compounds
4) atopic diseases
5) eczema
6) asthma (60%)
7) hay fever (30%)
8) hyperimmunoglobulin E syndrome*
9) Wiskott Aldrich syndrome
10) IgE myeloma
11) IgA deficiency
* serum levels of IgE may be determined by polymorphisms in PHF11 gene
Methods:
- RIA & PRIST (paper radioimmunosorbant test)
Specimen:
1) serum
2) fresh or store at 4 degrees C for < 72 hours
3) stable frozen at -20 degrees C for 6 months
4) stable frozen at -70 degrees C indefinitely
Notes:
- Measurement of total IgE can be misleading
- Patient with IgE antibodies to specific allergens may have total IgE serum levels within normal limits.
