My Gp has retired and the new GP has requested I have a blood test prior to renewing by B12 prescription.
I am diagnosed with PA just from them ruling out other things and because my levels keptdropping quickly even after loading doses.
After several years of trying various frequency of injections I have found that every 3 weeks keeps be going. My former Gp allowed me to self inject and was happy to treat my symptoms.
My question is that if I have a b12 serum test it is surely going to show it is sky high given I am injecting every 3 weeks. I was under the impression that once you are supplementing the b12 test would be useless other than showing you how quickly your body can get rid of it. I am concerned that the new Gp will say i don’t need them as often as my serum test is high. I do not want to make myself poorly just improve the point as I am really unable to function.
Is there any written guidance to back up that this is unnecessary? Any help really appreciated.
