I wonder if anyone can give insight to my B12 always at 1476 when I do blood tests. I stop injections a good week before test but it always the same. A bit puzzled this end. Any ideas?
Thank you

When you have an injection a lot of it gets eliminated in the urine quite quickly (about 80% over a day). The remaining 20% hangs around for a very long time. It takes about a year for half of it to go.
You would need to wait many months after an injection for levels to drop down to where they would be, for you, normally. If you inject more frequently than every three months then you would probably have to wait quite a bit longer.
Many thanks fbirder - I need 2 injections per week, every time I have tried to reduce I am in trouble so keep this regime going as it keeps me reasonably well but I didn't understand why body was hanging on to so much. Even tried a 3 week break - never again.
Why are you trying to reduce it?
If you need it, you need it!
I thought my body was not expelling the excess, but when I reduced the injections, I was nearly back to square 1. With the other 2 conditions it is very difficult to try and find out which one is out of kilter and needs adjusting but with twice weekly jabs the PA seems to toddle along quite well. The hypo is another matter and can be a real pain in the proverbial at times! That is why I really do not want to rock the boat as I have had a Hashi flare up just now - a real whopper which is jut calming down.
Thank you to all who responded, it has made me more confident to go and have the fangs checked!
My guess [and it is purely a guess] is that if the Serum B12 result is always coming back with the same '1476' number then that's probably the upper reportable limit of the assay the lab uses. The assays are not precise enough to give the same number each time on repeat on the same sample, never mind multiple samples, so it may be even higher. If you're being treated then it's likely to be of no consequence whatsoever.
