Is IgG therapy safe?
Since 1985, the federal government has required that all blood products undergo viral inactivation during the manufacturing process to protect patients against disease. Since that time, many safety processes have been developed and all have been successful in reducing the risks associated with the use of immunoglobulins, which are derived from blood plasma. There have been no reported cases of any disease transmission from IgG for the past 12 years. New diseases such as West Nile Virus and SARS are also strictly monitored. There have been no cases of West Nile Virus or SARS spread by the use of any brand of IgG. New tests and safety technology continue to be developed by IgG manufacturers.
