Total IgE Test - Serum

The Total IgE test, also called the Quantitative IgE test, measures the level of Immunoglobulin E (IgE) in your blood. IgE is an antibody involved in allergic reactions and the immune response to certain parasitic infections.

Your doctor may recommend this test if you have recurring allergy-like symptoms or if an allergic or other immune-related condition needs to be evaluated. A higher total serum IgE level may be associated with allergies, parasitic infections or certain immune system disorders. However, the result alone cannot confirm an allergy or identify what may be triggering your symptoms.

The test requires a blood sample. Fasting is generally not required, but let your doctor know about any medicines you are taking and follow any instructions provided before sample collection.

Why Is a Total IgE Test Recommended in Kottayam?

A doctor may recommend a Total IgE test to help assess:

• Symptoms that may be related to an allergic condition.

• Suspected allergic respiratory conditions, such as allergic asthma.

• A possible parasitic infection, when supported by symptoms or other findings.

• Certain immune system conditions.

• Children with a family history of allergic disorders, when clinically appropriate.

The test is only one part of an assessment. Depending on your symptoms and medical history, your doctor may recommend other tests, including allergen-specific IgE testing.

Who May Need a Total IgE Test?

Your doctor may consider an IgE test if you experience recurring symptoms that could be related to an allergy, such as:

• Stuffy or runny nose

• Frequent sneezing

• Wheezing or coughing

• Shortness of breath

• Itchy or watery eyes

• Itchy skin

• Hives or raised red patches

• Diarrhoea or vomiting associated with a suspected allergic reaction

These symptoms can have causes other than allergies. A healthcare professional can help determine whether a Total IgE test or another investigation is appropriate.

More About the Total IgE Test

What Is Immunoglobulin E (IgE)?

Immunoglobulin E (IgE) is one of the main types of antibodies produced by the immune system. It plays a role in allergic reactions.

When a person with an allergy encounters a substance their immune system recognises as an allergen, such as pollen, dust mites, animal dander or certain foods, the body may produce IgE antibodies against it. These antibodies attach to immune cells, including mast cells and basophils.

When the person is exposed to that allergen again, these cells may release substances such as histamine. This can cause symptoms like sneezing, itching, hives or breathing difficulties.

Some allergic reactions can be severe. Anaphylaxis is a medical emergency and requires immediate medical attention.

What Does a Total IgE Test Measure?

The Total IgE test measures the overall amount of IgE in your blood. It does not measure IgE against one specific allergen.

The result may help your doctor assess a possible allergic condition alongside your symptoms and medical history. A specific IgE test may be used when your doctor needs to investigate sensitivity to a particular allergen.

Other names: IgE allergy test, Total IgE, Quantitative IgE, Immunoglobulin E Total, Total Serum IgE.

Total IgE Normal Range

The Total IgE normal range depends on age, the laboratory’s testing method and its reference intervals. There is no single range that applies to every laboratory or age group.

The following are indicative age-wise reference values. Your laboratory report may use different limits.

Some laboratories may use an adult reference range such as 0–113 kU/L. Always refer to the range and units printed on your report when interpreting your result.

Note: These values are general examples, not universal diagnostic cut-offs. The units kU/L and IU/mL are numerically equivalent for IgE.

What Does a High Total IgE Level Mean?

A high Total IgE level means that the amount of IgE in your blood is above the reference range used by the laboratory.

An increased IgE total antibody level may be associated with:

• Allergic conditions, such as allergic rhinitis, asthma or eczema

• Parasitic infections

• Certain immune system disorders

A high result does not automatically mean that you have an allergy, identify the allergen or show how severe a reaction may be. Your doctor will interpret it alongside your symptoms, medical history and other findings. If needed, they may recommend specific IgE testing or further investigations.

A normal Total IgE result does not completely rule out an allergic condition.
