Congrats on getting your LVN license!
This is a sticky situation indeed. Although CA LVNs with IV certifications can give blood products, I am not sure that extends to immunoglobulins. Yes, it's obtained from blood but, if I were in your shoes, I would have the board spell it out for me in black and white.
Kudos to you for taking the time to verify that this is safe for you and, ultimately, your future patients!
