This test measures IgG antibodies, the most abundant immunoglobulins responsible for long-term immune protection.
Diagnostic Value: Abnormal IgG levels can indicate chronic infection, immune deficiency, or excessive immune activation.
Clinical Significance: IgG testing helps evaluate immune response capacity, particularly in patients with persistent respiratory or allergic symptoms.
Symptom Correlation: Altered IgG levels may correlate with fatigue, frequent infections, or chronic inflammation.
Because it reflects sustained immune defense, Total IgG testing helps determine immune resilience in allergic and inflammatory airway diseases.
