IgG is an important antibody and it is the most abundant antibody in the human body. The amount of IgG in the body varies from person to person, and is typically measured through a blood test.
The normal range of IgG levels in healthy adults is between 7.0 to 16.0 grams per liter (g/L). A person's IgG level can also be affected by age, with lower levels in children and higher levels in adults.
It is important for people to maintain sufficient IgG levels in their body in order to fight off infections and other illnesses. If a person's IgG levels are lower than normal, they may be more susceptible to illnesses.
If a person's IgG levels are too high, it could be a sign of an underlying medical condition, such as an autoimmune disorder or a chronic infection. It is important to consult with a doctor if a person's IgG levels are out of range so that the underlying cause can be diagnosed and treated.
Overall, the amount of IgG in the body should be within the normal range. However, if a person's IgG levels are outside of the normal range, they should talk to their doctor to determine the cause and take any necessary steps to ensure their IgG levels remain within the normal range.
