What Is an IgE Antibody Test?
The IgE Antibody Test is a blood test that measures the level of immunoglobulin E (IgE) in your blood. IgE is a type of antibody your body makes to fight off things like pollen, dust, or certain foods. However, sometimes your body makes too much IgE, which can cause allergies or other health problems. Because of this, doctors often use the IgE Antibody Test to help diagnose allergies and some immune system issues.
Why Is the IgE Antibody Test Done?
Doctors order the IgE Antibody Test for several reasons. Most often, it helps find out if you have allergies. For example, if you have symptoms like sneezing, itchy skin, or trouble breathing, this test can help. Sometimes, doctors use it to check for immune system problems or certain infections. In many cases, the test is part of a larger allergy testing plan.
When Should You Get an IgE Antibody Test?
There are several situations when your doctor may suggest this test. For instance, you may need it if you:
Additionally, if you have a family history of allergies, your doctor may recommend this test.
How Is the IgE Antibody Test Performed?
The IgE Antibody Test is simple and quick. First, a healthcare worker cleans your arm. Next, they use a small needle to take a sample of your blood. The blood goes to a lab for testing. Usually, the whole process takes less than 10 minutes. Afterward, you can go back to your normal activities.
How to Prepare for the Test
Most people do not need to do anything special before an IgE Antibody Test. However, it is a good idea to tell your doctor about any medicines you take. Sometimes, certain drugs can affect your results. For example, allergy medicines or steroids may change your IgE levels. Because of this, your doctor may ask you to stop some medicines before the test.
Understanding IgE Antibody Test Results
After the lab tests your blood, your doctor will get the results. The results show your IgE level, usually in units called IU/mL (International Units per milliliter). Here is what the results may mean:
However, IgE levels can vary from person to person. Therefore, your doctor will look at your results along with your symptoms.
What Do Abnormal Results Indicate?
If your IgE level is higher than normal, it may mean:
On the other hand, a low IgE level may point to rare immune problems. Still, many people with abnormal results do not have serious health issues. Because of this, doctors use other tests and your medical history to make a diagnosis.
Next Steps After Receiving Results
Once you get your results, your doctor will explain what they mean. If your IgE level is high, you may need more allergy testing. For example, your doctor may suggest skin tests or specific IgE blood tests for certain allergens. In some cases, you may need treatment for allergies or asthma. If your IgE level is low, your doctor may check for other immune problems.
Risks and Safety of the IgE Antibody Test
The IgE Antibody Test is very safe. Most people only feel a small pinch when the needle goes in. Sometimes, you may have a little bruising or soreness afterward. Rarely, you might feel dizzy or faint. However, serious problems are very uncommon. According to the CDC, blood tests like this are safe for most people.
