Introduction

Your immune system helps protect you from foreign antigens, but sometimes it can become hyperactive, which may be associated with elevated blood IgE levels. While High IgE antibodies are crucial in fighting allergens and parasites, an abnormally high level can lead to serious health concerns like chronic allergies, asthma, and a hyperactive immune system, causing serious immune disorders

In this blog, we will discuss the normal IgE level by age, its role, and how to manage and control high IgE levels.

What Is Ige?

IgE antibody is produced by our immune system in response to certain conditions, like allergic reactions, asthma, parasitic infections, and some immune disorders. which can be measured through an IgE level test. The normal range is around 150-200IU/mL, and a level above indicates a serious health condition that requires immediate attention.

What are High Ige Level Symptoms?

A high IgE level does not directly indicate any symptoms but may be associated with the underlying health condition. Symptoms include:-

• Sneezing and Coughing
• Runny nose
• Itchy and watery eyes
• Hay Fever (allergic rhinitis)
• Skin Rash like eczema
• Wheezing (due to inflamed airways)
• Difficulty breathing (shortness of breath)

Parasitic Infection Symptoms

Sometimes the High IgE Level can be due to the parasite, which may show symptoms like

• Fever & Persistent Fatigue
• Nausea & Vomiting
• Cramping with Abdominal Pain
• Chronic Diarrhea
• Swollen Lymph Nodes
• Unexplained Weight Loss
• Iron-Deficiency Anemia
• Skin Rashes & Irritation
• Respiratory Cough

Symptoms of Primary Immunodeficiency Disorders (Inherited).

Depending upon the specific disorder, some of the associated symptoms include: -

• Recurrent skin infections related to staphylococcal
• Respiratory issues due to lung infections like pneumonia or fungal infections like Aspergillus
• High Serum Ige level more than 2000 IU/ml (eosinophilia)
• Musculoskeletal-related conditions leading to scoliosis, osteopenia, and other bone deformities.

What Are the Causes of High Ige Level in Blood?

Depending upon the patient's condition and health, here are some of the common causes responsible for High IgE level this include:-

Allergic Conditions: When our immune system develops hypersensitivity due to the pollen dust or food allergen, it can lead to symptoms like allergic rhinitis, asthma, and atopic dermatitis (eczema), which can increase blood IgE levels.

Parasitic Infection: Parasites belonging to the classes Cestodes (tapeworm) and Nematodes (hookworm and roundworm) can lead to increased IgE production.

Immune Disorders: This includes hyper IgE syndrome, such as primary immunodeficiency syndrome, like eczema, pneumonia, and autoimmune disorders like lupus, causing recurrent infection.

Certain Malignancies: Cancerous conditions, like Hodgkin's lymphoma (cancer of the lymphatic system) and myeloma (a type of blood cancer), can elevate your IgE level.

Family History –If you have a person with a history of allergic response, there may be a high chance of increased risk of high IgE levels, which requires genetic testing.

What are Normal IgE Levels?

IgE level in blood can be measured through the IgE blood test, which provides a detailed analysis of the IgE count in your blood. In addition, allergy testing based on the type may be referred. IgE levels fall in the range of 0 and 150 IU/ml above the range may indicate allergic or immune-related conditions.

Normal Ige Level: Table Interpretation

Normal Ige Count by Age (Adults and Children)

Below is the table that denotes the Ige level count (age-wise). It is important to consult with your doctor before following this data

Key Points To Consider

• IgE ranges differ by lab condition, so always check your lab’s reference values.
  
• Normal adult IgE is usually 0–100/150 IU/mL, but much lower in young children.
  
• Mildly high IgE may indicate mild allergies or a normal variant.
  
• High IgE is often linked to allergies, eczema, asthma, or infections.
  
• Very low IgE is rare and usually not clinically significant.
  
• IgE levels change with age, rising in childhood and falling in adulthood.
  
• Normal total IgE doesn’t rule out allergies, as specific IgE may still be high.
  
• Smoking can slightly raise IgE levels.
  
• The doctor also checks symptoms to interpret test results, not IgE numbers alone

What Does a High IgE Level Indicate?

How to Control IgE Level?

High IgE levels can be controlled through medication along with a good lifestyle. Some of the good health practices include: -

• Stress management: This can help control allergic and inflammatory conditions.
• Balanced Diet: Include fresh fruits, vegetables, healthy fats, and probiotics that control inflammation and IgE levels.
• Frequent exercise: beneficial for reducing asthma symptoms and improving overall health.
• Adequate Sleep: Improves the immune system to function properly.
• Regular health checkup: Get yourself checked. If you have a family history or any other immune-related disorder.

Treatment focuses on long-term management and control of the specific condition leading to high IgE levels. This includes
