Hello @diana333 and welcome to Mayo Connect. I see that your Vitamin B12 levels are concerning you. I'm wondering how you are feeling. Any problems that concern you? Are you currently taking Vitamin B12 supplements?

I recommend that you take a look at another discussion on Connect that deals with high levels of B12. Here is the link to that discussion
https://connect.mayoclinic.org/discussion/high-levels-of-b12/

I'm also wondering what other health conditions you might have that would be contributing to this.

Has your doctor said anything about these levels? Does he/she have any explanations?
