About this test

Holotranscobalamin represents only 10-30% of the Vitamin B12 circulating in the blood, but is the ONLY form of Vitamin B12 that is taken up and used by cells of the body, hence it's other name : ACTIVE B12

Vitamin B12 is an important vitamin, essential for the normal functioning of many body processes. Deficiency can lead to anaemia (poor quality red blood cells) and neurological (nerve) disorders. It is most abundant in meat products so vegetarians are more vulnerable to deficiency of this vitamin. Pernicious anaemia develops if uptake of vitamin B12 into the blood from the gut is absent or severely impaired, and even if a diet rich in the vitamin is taken, deficiency will occur if this disease is present. Recent evidence suggests that mild deficiency is probably more common than previously thought, and that the threshold for diagnosis may be lower than previously considered. Mild deficiency may explain the presence of fatigue and a host of other limiting symptoms.
