Immunoglobulin E, Total
Also known as: IgE
Use
Evaluate immunoglobulin status in possible atopic disease
Special Instructions
If a red-top tube is used for specimen collection, the serum should be transferred to a plastic transport tube.
Limitations
Normal IgE levels do not exclude allergic phenomena. Although elevated IgE levels may indicate allergic conditions, a significant number of individuals with allergies and elevated IgE specificities may have normal total IgE levels. Total IgE levels are useful as a marker but not definitive on their own due to variability among individuals and conditions.
