Test includes: |
Immunoglobulin E value. | |
Methodology: |
Chemiluminescence Immunoassay |
|
Synonyms: |
Immunoglobulin E, IGE TOTAL IgE
|
|
Clinical significance: |
In general, the total IgE level increases with the number of allergies which a person has and with the amount of exposure to relevant allergens. Significant elevations may be encountered not only in sensitized individuals but also in cases of IgE myeloma, pulmonary aspergillosis, and during the active stage of parasitic infestations. | |
