Hello I have given blood test 3 days back and my
vitamin b12 level was less then 50 . So doctor gave one injection which I need to take every alternative day for 2 week .
2 days back I took my 1 st injection and today I again gave blood test in other lab . And vitamin b12 level is showing 210.
How can vitamin level increase from less then 50 to more then 200 in 2 days ?
Is it laboratory mistake ?
