A member asked:
What does it mean if igg1 and igg3 are low?
A doctor has provided 1 answer
Need more workup: Depending on how low your igg1 is, you will need further testing to determine if your immune system is making appropriate levels of antibody to certain vaccinations. This will help determine if there is the need for igg replacement therapy (ivig). If you are not having recurrent infections, there is probably little need to worry.
