LOINC description : The fraction of vitamin B12 bound to transcobalamin II (TC-II), normally 30% of the
total, is considered the active fraction available to cells. There have been claims
in the literature that measurement of specifically the active fraction is an earlier
indicator of deficiency, although as of 2011 this claim is reported to be controversial
(Am J Clin Nutr. 2011 Jul;94(1):348S-358S. Epub 2011 May 18).;
