Introduction

Immunoglobulin G (IgG) is the most abundant type of antibody found in the body, playing a critical role in the immune system's ability to combat pathogens. Understanding the factors that influence serum IgG levels is crucial for diagnosing and managing various health conditions.

Factors Affecting Serum IgG Levels

Genetic Factors

There is a strong hereditary component to IgG levels, with genetic variations accounting for approximately 30-50% of the interindividual variability. Specific genes, such as those involved in the HLA complex, have been linked to the regulation of IgG production.

Age and Gender

IgG levels vary by age, typically increasing after birth, peaking in early adulthood, and declining in older age. Females often have slightly higher IgG levels compared to males, possibly due to hormonal influences.

Nutrition

Nutritional status significantly affects IgG levels. Protein malnutrition can lead to lowered IgG concentrations, while specific micronutrients such as zinc and vitamin D are vital for maintaining optimal IgG levels.

Infection and Disease

Chronic infections and autoimmune diseases can dramatically increase IgG levels as part of the body's response to prolonged antigenic stimulation. Conversely, certain conditions, such as primary immunodeficiency disorders, may result in abnormally low IgG levels.

Medication

Certain medications, including immunosuppressants and corticosteroids, are known to affect IgG levels by altering immune system activity. Monitoring IgG levels can provide insight into the efficacy and side effects of these treatments.

Environmental Influences

Environmental factors such as exposure to pollutants and stress can influence IgG levels. For instance, cigarette smoking has been associated with altered IgG concentrations due to its impact on immune function.
