The Haemophilus influenzae type B IgG Antibody Test measures IgG levels against Hib bacteria to evaluate immune protection. Adequate antibody levels reflect vaccine response or past exposure, while low levels may indicate susceptibility to infection. This test supports assessment of immune status in children, immunocompromised patients, or individuals at risk for invasive Hib disease such as meningitis or pneumonia.
The IgG Subclasses Panel measures four IgG antibody subclasses (IgG1, IgG2, IgG3, IgG4) to assess immune system function. Abnormal levels may indicate primary immunodeficiency, recurrent infections, autoimmune disease, or allergic conditions. Doctors order this test for patients with chronic sinus, lung, or ear infections or suspected immune imbalance. Results provide key insight into antibody response, guiding diagnosis, treatment, and long-term immune monitoring.
The Total Immunoglobulins Panel measures IgA, IgG, and IgM levels to evaluate immune system function. Abnormal results may indicate immune deficiency, chronic infections, autoimmune disorders, or certain blood cancers. IgA helps protect mucous membranes, IgG provides long-term defense, and IgM is the body’s first response to infection. Doctors use this blood test to diagnose, monitor, and manage immune-related conditions and overall immune health.
