What it measures
- Total immunoglobulin E — Reflects the overall level of IgE antibodies in the blood, which can be elevated in allergic conditions.
What the test involves
A healthcare professional collects a small blood sample, typically from a vein in your arm. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test to help assess symptoms that could be related to allergies, such as persistent sneezing, itching, or skin reactions. It can also be used to monitor certain immune conditions, but it is not a standalone diagnostic tool.
