Active B12, what is this test for?
Vitamin B12 and folate are primarily requested to help diagnose the cause of macrocytic anaemia. Folate and vitamin B12 may be used to help evaluate the nutritional status of a patient with signs of significant malnutrition or malabsorption. This may include those with alcoholism and those with disorders associated with malabsorption such as coeliac disease, Crohn’s disease, and cystic fibrosis. B12 and folate may also be used to help diagnose the cause of mental or behavioural changes, especially in the elderly.
In patients with known vitamin B12 and folate deficiencies, these tests may be used occasionally to help monitor the effectiveness of treatment. This is especially true in patients who cannot absorb vitamin B12 and/or folate and must have lifelong treatment.
