Give IM B12 to sop up any empty B12 binding sites. Accurate diagnosis is also important because the anaemia can be treated by oral vitamin B12 rather than by the vitamin given by intramuscular injection [6]. It is usually performed to figure out if the patient has a deficiency of intrinsic factor, which you need to make in order to bind and absorb B12. Serum beta-carotene may be used as a first-line screening test for fat absorptive capacity.
