Intrinsic factor test

Hello all. I have found a very reasonably priced intrinsic factor private lab test. Do I have to stop B12 injections before taking this test? I SI EOD which has saved me from being totally bed ridden, which I was for three months.

Thank you

you can get false positives if test is done too close to an injection. The exact test method determines how close is too close. Could be 10 days or could be 48 hours. Suggest you ask the lab what the timescale is,
