IgG Test Preparation

Here is the basic preparation for the IgG Test.

Before Test

No fasting or special preparation required.
Inform your doctor about medications or allergies if relevant.

During Test

A blood sample is collected from a vein in your arm.

After Test

You can resume normal activities immediately.
No specific post-test instructions are typically needed

IgG Test Procedure

During an IgG Test Procedure, a healthcare provider will:

Collect a blood sample from a vein in your arm.
Send the blood sample to a laboratory for analysis.
Assess IgG antibody levels in the blood to detect infections or immune disorders.
Interpret the results to aid in diagnosis and treatment decisions

IgG Test Result

Here are the interpreted IgG Test Results.

Low Levels: Low IgG levels may indicate a weakened immune system, potentially increasing susceptibility to infections.
Normal Range: Falling within the normal range suggests a healthy immune system with balanced antibody levels.
High Levels: Elevated IgG levels can be a sign of recent or chronic infections or autoimmune conditions.

Consult a healthcare professional for further evaluation if your levels are high and you're experiencing symptoms.

The normal reference range for IgG levels in adults can vary slightly depending on the laboratory and measurement units used.

IgG Level	Normal Range
Adult	700 - 1600 mg/dL

IgG Test Interpretation

Here is the basic Interpretation value of the IgG Test.

IgG Level (mg/dL)	Interpretation	Risk
Below 700	Low IgG levels	Increased infection
700 - 1600	Normal IgG levels	Balanced immunity
Above 1600	Elevated IgG levels	Possible autoimmune

IgG Test High Levels

Here are the causes of high IgG levels:

Causes	Description
Infections	Chronic or bacterial infections can elevate IgG.
Autoimmune Diseases	Conditions like lupus may increase IgG levels.
Chronic Inflammatory Disorders	Conditions like rheumatoid arthritis can elevate IgG.
Certain Cancers	Blood cancers like multiple myeloma can cause high IgG.
Liver Diseases	Hepatitis and cirrhosis may lead to increased IgG.

IgG Test Low Levels

Here are the causes of low IgG levels:

Causes	Description
Immunodeficiency Disorders	Primary or secondary immunodeficiency disorders.
Certain Medications	Immunosuppressive drugs or corticosteroids use.
Chronic Infections	Prolonged viral or bacterial infections may reduce IgG.
Liver Disease	Conditions affecting the liver can lower IgG levels.
Malnutrition	Severe malnutrition and poor diet can lead to IgG deficiency.

IgG Test FAQ

What is a positive IgG test?

A positive IgG test indicates the presence of IgG antibodies specific to a particular antigen, such as a virus or other pathogens. In the context of infectious diseases, a positive IgG test suggests past exposure to the specific pathogen or vaccination. IgG antibodies are typically developed after an initial infection or immunization and provide long-term immunity against subsequent infections. A positive IgG test alone does not indicate a current or active infection but rather indicates previous exposure or immunization. The interpretation of IgG test results should be done in conjunction with clinical symptoms, medical history, and other laboratory findings. Healthcare professionals are best suited to provide accurate interpretation and guidance based on the specific context of the individual.

What is IgG testing?

IgG testing is a diagnostic tool that measures Immunoglobulin G (IgG) antibodies in the blood. These antibodies are part of the immune system's response to infections or other immune challenges.

Why is IgG testing important?

IgG testing helps identify allergies, intolerances, and immune system responses to various substances, aiding in the diagnosis of food sensitivities, autoimmune diseases, and infections. It can guide dietary and lifestyle changes for improved health.

What can IgG testing diagnose?

IgG testing can diagnose food sensitivities, environmental allergies, autoimmune diseases, and chronic infections. It provides insights into conditions like celiac disease, rheumatoid arthritis, and irritable bowel syndrome.
