Can you do the intrinsic factor blood test if you get B12 injections?

Question from Daisy: The intrinsic factor blood test, can you have it done if you are already getting B12 injections?

A: Yes, you can.
The antibodies you make just remain and can still be detected as the cause of your vitamin B12 deficiency, even if you supplement B12 with injections.
