Happy new year to everyone. I have a question, hope someone will be able to help. Just before 31 Dec I got blood results for vitamin B12. I have 1467 while the reference range goes from 141 to 489. I was getting B12 injections for 3 month but it was last summer. So obviously I have too much of it in my blood now. Why is this since months passed since my injections and can it be dangerous. Thanks.
