What's this test for?

This test is ideal if you're experiencing frequent infections, chronic digestive issues, or unexplained inflammation. It helps identify immune system deficiencies or overactivity that may be causing recurrent illnesses, food sensitivities, or autoimmune symptoms. Many people use this test when they suspect their immune system isn't functioning properly but want to understand what's happening at a deeper level.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your IgG levels mean for your immune function and overall health. These notes include personalized recommendations like dietary adjustments, lifestyle changes to support immunity, or whether you should consult an immunologist or specialist. You'll also get the standard lab report and can track your IgG levels over time using our trends feature to monitor how your immune system responds to interventions.

What's included in this test?

This test measures IgG (Immunoglobulin G). This test measures Immunoglobulin G (IgG), the most abundant antibody in your blood that protects you from infections and indicates how well your immune system is functioning. IgG levels help identify immune deficiencies that make you vulnerable to infections, chronic inflammations and autoimmune conditions, and certain blood disorders. Together with your symptoms, these measurements provide insights into whether your immune system is underactive, overactive, or functioning normally.

How should I prepare for this test?

No special preparation is typically required for an IgG test. You can eat and drink normally before your blood draw, and you don't need to fast. However, let your healthcare provider know about any medications or supplements you're taking, as some immune-suppressing drugs may affect results. Schedule your test when you're not currently fighting an acute infection for the most accurate baseline reading.

When will I get my results?

Most IgG test results are available within 1-3 business days after your blood sample reaches the laboratory. You'll receive an email notification when your results are ready to view in your secure online account. Complex cases or samples requiring additional testing may occasionally take a bit longer, but the majority of routine IgG tests are processed quickly.

Who should consider getting this test?

This test is important for people with frequent infections like sinusitis, bronchitis, or ear infections that suggest weakened immunity. It's also valuable for those with chronic digestive problems, suspected autoimmune conditions, or a family history of immune disorders. If you're experiencing unexplained fatigue along with recurrent illnesses, or if your doctor suspects an immune deficiency or myeloma, this test provides crucial diagnostic information.

What symptoms indicate I may need this test?

Common symptoms include getting sick more often than others around you, infections that are severe or hard to shake, chronic sinus or respiratory infections, and persistent digestive issues. You might also experience ongoing fatigue, unexplained weight loss, or notice that minor infections take unusually long to heal. These signs may indicate that your immune system needs evaluation through IgG testing.

How can I naturally support my immune system?

Supporting healthy IgG levels starts with eating a nutrient-rich diet full of colorful fruits, vegetables, lean proteins, and healthy fats that provide vitamins C, D, zinc, and selenium. Getting 7-9 hours of quality sleep, managing stress through meditation or exercise, and staying physically active all help maintain robust immune function. Avoiding smoking, limiting alcohol, staying hydrated, and practicing good hygiene also support your body's natural antibody production.

What is IgG and why does it matter?

IgG (Immunoglobulin G) is the most common type of antibody in your blood, making up about 75-80% of all antibodies. It's your immune system's long-term memory, protecting you from bacteria, viruses, and other invaders you've encountered before. IgG levels that are too low leave you vulnerable to infections, while unusually high levels can indicate chronic inflammation, autoimmune disease, or certain blood cancers, making it a crucial marker of immune health.

What does high IgG mean?

Elevated IgG levels typically indicate that your immune system is actively fighting something, such as a chronic infection, ongoing inflammation, or an autoimmune condition where your body mistakenly attacks itself. High IgG can also be associated with certain liver diseases, blood disorders like multiple myeloma, or chronic inflammatory conditions. Your doctor will consider your symptoms and may order additional tests to determine the specific cause of elevation.
