Understand immune health with our advanced antibodies Immunoglobulins IgG, IgM, IgA Blood Test. Actionable insights & proactive health management.

Immunoglobulins (IgA, IgG, IgM) are antibodies that play a critical role in your body's immune system. This test measures the levels of these antibodies in your blood, offering essential insights into your immune health. IgA antibodies are found in blood, saliva, respiratory secretions, and the fluid in your stomach. They are important in defending the respiratory and gastrointestinal tracts against infection. IgG antibodies are the most common immunoglobulin in blood and help fight against viral and bacterial infections. They also form part of the immune system's "memory" and are very important in the body's response to infections that it has encountered before. IgM antibodies are produced as part of the body's initial response to infection, so levels of IgM rise at the start of an infection. High or low levels of immunoglobulins can indicate various conditions, from chronic infections and autoimmune diseases to liver issues and certain types of blood cancer. At One Day Tests, we are dedicated to giving you a comprehensive view of your health. Our Immunoglobulins Blood Test is a crucial tool for timely intervention and effective management of potential health risks.

Parents investigating potential food sensitivities in children. People considering an elimination diet and wanting data to guide which foods to remove.

What's Included

IgE and/or IgG antibody measurement
Panel of common allergens (varies by provider)

Preparation Required

No fasting required. Continue eating your normal diet for at least 2–4 weeks before testing — avoiding suspected trigger foods can cause false negatives. Inform the clinic of any antihistamines or immunosuppressants you're taking, as these can affect results.

Biomarkers Tested

6
Globulin g/dL

A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.

IgG mg/dL

Immunoglobulin G (IgG) is the most common type of antibody in the blood, important for fighting bacterial and viral infections.

Globulin g/dL

A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.

Albumin g/dL

The most abundant protein in blood, produced by the liver. Albumin maintains blood volume and pressure, and transports hormones, vitamins, and drugs. Low levels indicate liver disease, kidney disease, malnutrition, or chronic inflammation.

Globulin g/dL

A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.

Total Protein g/dL

Measures the combined amount of albumin and globulin proteins in your blood. These proteins are essential for fighting infections, blood clotting, and transporting substances throughout the body.
