Hi, I live in India and recently found a test available:Transcobalamin. Link: http://www.lalpathlabs.com/FullTestMenuResult.aspx?id=Code&Search=RW200 Will this test tell me if I have malabsorption or what? I know TC is used to bind B12 and carry it further inside the body. So will the test results differ if I take B12 or is it independant of that? Will this test be of help to me,to determine my deficiency? Also,what does a deficiency of transcobalamin mean? A person has to take More B12?
