Test Description

The total IgE test may be used to screen for and detect allergic diseases.

When should this test be ordered?
A total IgE test may be ordered when a person has periodic or persistent symptoms that may be due to an allergic reaction, especially when the potential allergen is unknown.
High Risk · > 114 (kU/L)
An increased total IgE level indicates that it is likely that a person has one or more allergies. Allergen-specific IgE levels will increase after an exposure and then decline over time, thus affecting the total IgE level.
Borderline Risk · None
Not determined for this test.
Low Risk · 0 - 113.99 (kU/L)
Within Reference Range
Testing Method Used
Sandwich Immunoassay.

Please ship samples daily.
Improvements and Prevention
Limiting the things which you are allergic to. The total IgE concentration is not influenced by lifestyle changes and lowering it would not have an effect on the number or type of allergies that you have.
Specimen Type
Serum
Fasting Required
No, but may be done with other tests that requires fasting.
