I'm a 37 year old and I just had a complete blood workup done a week ago due to ongoing muscle and joint pain I've been experiencing for quite a while. The blood work was essentially normal except for slightly elevated triglycerides and cholesterol, but what really stood out was that my B12 level was elevated at 1299. I believe the normal range is 200-900. I went online to look for possible causes for elevated B12 levels in the blood, and most of the information I found was related to B12 deficiencies. The small bit of information I found regarding elevated B12 stated that it could be associated with some forms of leukemia. My doctor did send me a letter interpreting the blood results, and he stated that I do not need any further testing. I do have an appointment to see him next week to discuss things, but I don't know whether or not to push for more testing since he doesn't seem too concerned. Does anyone have experience with elevated B12 levels? If so, does anyone know if the elevated B12 levels associated with leukemia are drastically higher than the normal lab range? Or is the 1299 I had on my test considered very high. I would greatly appreciate any feedback. This has me really worried. Thank you.
