In the past month i have had my b 12 tested 3 times and that was at 2 different labs. all 3 came back elevated b12 200, then 1723, then 2000 again.

Whats the question?: Are you asking if a B12 of 2000 is dangerous? Are you asking why one of them is lower? If you're taking B12 supplements, its pretty normal to be high. But probably not dangerous.

B12: laboratory tests that may be used to help detect B12 and folate (folic acid) deficiencies include homocysteine and methylmelonic acid (MMA). Homocysteine and MMA are elevated in B12 deficiency while only homocysteine, and not MMA, is elevated in folate (folic acid) deficiency. https://labtestsonline.org/understanding/analytes/vitamin-b12/tab/test/
