Serum total vitamin B12 and HoloTC. a Serum total vitamin B12 and HoloTC versus time. b Serum total vitamin B12 versus HoloTC. Reference A B12 low = low limit for serum vitamin B12 concentration defined by Oh and Brown (2003). Reference B B12 low = low limit for serum vitamin B12 concentration defined by Bates and Lewis (2012). Lab B12 RI low = lower limit of serum vitamin B12 concentration reference interval defined by the testing laboratory. Lab HoloTC RI low = lower limit of serum holotranscobalamin concentration reference interval defined by the testing laboratory
