   Serum vitamin B12 is a medical laboratory test that measure vitamin B 12 only in the blood binding to both transcobalamins. [1] . Most of the time, 80–94% of vitamin B 12 in the blood binds to haptocorrin, while only 6–20% is binds to transcobalamin ll. [2] Only transcobalamin ll is "active" and can be used by the body. [1] .
