Hello
Thanks for posting your health query at DoctorSpring.com
Ig G indicates the immunity acquired to any infection.
A raised Ig G merely indicates that you are already immune to this infection.
It can be due to past vaccination also.
There is no cause of concern in this report, please relax.
It is more important to get a Rubella Ig M measured, as that , if positive, would indicate active recent infection that needs further steps.
All the best.
Please feel free to discuss further.
Regards.
