What is the IgE test? What is the IgE test normal range?

Time to read 3 min

When exposed to a potential allergen or pathogen, our bodies release antibodies as a response. This raises the level of IgE in the blood, which can be tested through a test to determine whether you are experiencing an immune reaction.


The IgE test is vital for individuals that are prone to allergic reactions or those that are immuno-compromised. The test can quickly reveal whether you are at risk of developing a chronic immune response, which would require further treatment.

What is IgE?

The immunoglobulin E IgE is an antibody produced as a response to allergens, pathogens, and other major threats. The IgE level can be measured as a part of a total IgE test in iu ml, giving us the likelihood that you are currently dealing with an illness.


The IgE levels indicate a more immediate allergic reaction in the case of the immune response. The test of IgE can indicate whether you require treatment or medication, but can't determine what is the allergen or pathogen affecting you.


You would require further testing and analysis to determine whether you are exposed to toxins, pathogens, infections, or allergens. Levels that are above 150 kU/L are considered high, requiring further testing and analysis. 

Understanding the IgE test normal range

The normal range of IgE is generally 150 to 1,000 UI/ml, but the accepted upper limit of IgE is 300 UI/ml. Your doctor will have to check your medical history, current health, and whether you have a chronic illness to interpret the results effectively.

What factors can influence the IgE normal range?

The normal range of 2-150 kU/L level of IgE in the blood can be impacted by several factors. The specific IgE test needs to take into account different factors so that the baseline can be understood with better information.


Factors such as family history, background, medical history, lifestyle, and chronic illnesses, can elevate the baseline levels of IgE. Your doctors will have to analyse these factors prior to starting treatment.

Key symptoms indicating an allergic reaction

There are several cases in which an allergic reaction will require an IgE test to determine the root cause. Your IgE levels can provide more information to your healthcare specialist.

Redness of skin

You can experience redness of the skin, which is one of the first few indicators of an immune response. This can be due to the exposure to an allergen or pathogen, which has quickly created redness.

Throat closing

One of the first few responses to an allergen is your throat closing. This can feel like you aren't able to swallow correctly and require effort to swallow at all. This should be taken seriously as it can escalate.

Difficulty breathing

Your immune system may be activated across your respiratory system, which can cause the sensation of difficulty breathing. This is one of the most important indicators in the case of someone with a peanut or pollen allergy.


Chronic cold or cough

Long-term exposure to an allergen or infection can lead to a chronic cold or cough sensation. This may require medication to treat, but it's recommended to get an IgE test done to check for levels.

Congestion feeling

You may experience congestion in your lungs, making it harder to breathe as well. This sensation may be followed by other accompanying symptoms such as difficulty breathing and chronic cold.


Burning sensation on skin

You may experience a burning sensation on your skin as a response to elevated IgE in the blood. The allergic reaction can escalate based on the severity of the response.

Where can I get an IgE test in India?

What is the cost of IgE test in India?

The IgE test cost in India is INR 2900 which includes IgE, skin, respiratory, and other potential allergens.

How long will the IgE test results take?
