Ferritin: the most accurate marker of total body iron stores and the first component to fall in the setting of iron deficiency.

Serum Iron: the next most useful component, giving an estimate of iron being carried in the blood.

Transferrin: a protein which carries iron in the blood; it may be increased in the presence of inflammation or infection anywhere in the body and is therefore less useful.

Saturation Raio: mathematical equation that divides serum iron into total iron binding capacity (TIBC), and then multiplies by 100. This value represents the percentage of how much iron is bound to the blood protein transferrin.

Vitamin B12:measures the level of Vitamin B12 in the blood. B12 is an essential vitamin which is necessary for the formation of healthy red blood cells and proper nerve function. B12 is not produced by the body and must be taken in through a person's diet. Good sources of Vitamin B12 include red meat, fish, poultry, milk, yogurt and eggs. A deficiency in B12 can cause a condition known as Macrocytic Anaemia in which red blood cells are larger than normal. Common causes for Vitamin B12 deficiency are malnutrition, liver disease, alcoholism and malabsorption disorders such as Coeliac Disease, Cystic Fibrosis and Inflammatory Bowel Disease.

A Vitamin B12 test is typically ordered when a person is experiencing common symptoms of deficiency such as diarrhoea, dizziness, fatigue, pale skin, loss of appetite, rapid heartbeat, shortness of breath, tingling or numbness in the extremities. and a sore mouth or tongue. It may also be done to monitor people being treated for deficiency or malabsorption.
