Why Do I Need IgE Blood Test?
An IgE blood test is a diagnostic tool that measures the level of IgE antibodies in your blood. But why would you need an IgE test? If you're experiencing the below-mentioned symptoms, an IgE allergy test may help determine if you have an allergic reaction. An IgE test can also help identify the allergen causing the symptoms, such as pollen, dust, mold, or certain foods.

- Itchy, red, or watery eyes.
- Hives (itchy and raised red patches all over the skin)
- Nausea and vomiting.
- Shortness of breath (dyspnea)
- Abdominal pain.
- Sore throat (pharyngitis).
- Swollen lips, tongue, eyes, or overall face.
- Wheezing and tightness in your chest

How To Prepare For IgE Level Test?
There are no special preparations needed when getting an allergy blood test. In certain cases, the healthcare provider might want you to fast (not consume any food for a few hours) before the test.
However, if you are currently taking any anti-allergic medications, it is important to let the provider know this before the test. They might request you stop taking this medication before the test for accurate results.
What Happens During IgE Allergy Test?
An IgE test only takes a few minutes.
- As per the scheduled time of the blood test, a Lab Technician who usually takes blood samples will arrive.
- A thin needle will be used to draw blood from your arm’s vein.
- The needle might cause a mild pinch and some discomfort.
- The lab technician then fills a collection tube with blood and then removes the needle from the skin.
- They place a small bandage on the arm.
Please note: There might be slight pain or bruising at the spot where the needle was inserted, but most of the symptoms go away quickly.
