Total IgE Explained

Stay tuned to learn why a high IgE isn’t the whole story and the one tip that really matters.

IgE for kids

Think of IgE as a guard-dog antibody. Its job is to chase parasites, but sometimes it barks at harmless things like dust, pollen, or peanuts, causing itching and sneezing. When it barks, cells release histamine, causing itching, sneezing, wheezing, and hives.

Reading your IgE

Your lab report shows total IgE, the overall amount of allergy antibody, and specific IgE for each suspect. A class of two or higher means you’re sensitised, but only matters if you actually react.

Typical adult range

Most labs consider up to about 150 IU per milliliter normal for adults.

Why IgE spikes

Allergic conditions like hay fever, asthma and especially eczema can push IgE high. Parasites, smoking, and certain fungal lung allergies also raise the number. A stool test can confirm worm infection when IgE is high.

Finding the trigger

To pinpoint a trigger, doctors use skin prick tests or specific IgE blood tests. Write down what you ate, the symptoms, and timing before testing, and ask for a targeted panel instead of a full one. If your skin is covered in eczema, a blood test may be preferable.

Next steps

If a specific IgE matches a clear reaction, your doctor can suggest avoidance and possibly an adrenaline auto-injector. Don’t stop eating a food you tolerate without professional advice.

The one key tip

The most useful step is to ask your doctor for specific IgE tests only on items that have caused symptoms, rather than ordering a broad panel.
