Immunoglobulin Replacement Therapy Market size was valued at USD 13.51 billion in 2024 and is set to exceed USD 33.36 billion by 2037, registering over 7.2% CAGR during the forecast period i.e., between 2025-2037. In the year 2025, the industry size of immunoglobulin replacement therapy is evaluated at USD 14.29 billion. The market for the therapy has increased because of the rising number of patients with auto-immune diseases such as IVIG and Guillain-Barré Syndrome, as well as the clinical effectiveness of immunoglobulin in treating these problems. Hence, the increasing frequency of these diseases will escalate the growth of the market. According to a report every year, about 100,000 people globally contract GBS. Also, the predicted incidence of GBS in 2020 was 1.41 cases per 100,000 people a year, up from 0.89 cases in 2019. In 2021, the overall rate of GBS rose by 59%.

Furthermore, the market is driven by the rising incidence of immunodeficiency illnesses. Moreover, the increased prevalence of lifestyle-related issues like obesity and antibody deficiency illnesses are also propelling the market growth. Since immunoglobulin (IgG) replacement therapy is the only viable and effective treatment option currently on the market, demand for it is rising. The immunoglobulin (IgG) replacement therapy market is anticipated to expand quickly throughout the projected period.
