The Immunoglobulins A/G/M panel measures the levels of three types of antibodies in your blood: IgA, IgG, and IgM. Your immune system produces these antibodies to help fight off infections and other foreign substances. The results of this test can help your healthcare provider determine if your immune system is functioning properly.

Immunoglobulins (IgA, IgG, IgM) are critical antibodies that play essential roles in the body’s immune defense system, each with unique characteristics and functions.

Key Characteristics

Reference Ranges (Adult):

• IgG: 6-16 g/L
• IgA: 0.9-4.5 g/L
• IgM: 0.5-2.0 g/L

Clinical Significance Diagnostic Applications: • Assess immune system health • Detect potential immunodeficiencies • Evaluate chronic infections • Screen for autoimmune disorders

Potential Abnormal Findings High Levels May Indicate: • Chronic infections • Inflammatory conditions • Autoimmune diseases • Plasma cell disorders

Low Levels May Suggest: • Immunodeficiency • Increased infection risk

Potential autoimmune conditions, Specific Immunoglobulin Insights

• IgG: • Most abundant immunoglobulin • Provides long-term immune memory • Crosses placenta to protect newborns
• IgA: • Protects mucosal surfaces • Common in respiratory and gastrointestinal tracts • Deficiency affects 1 in 500 people
• IgM: • First antibody produced in immune response • Critical for initial pathogen detection • Plays key role in early infection fighting Immunoglobulin testing provides crucial insights into immune system function and potential health challenges.
