What's this test for?
There are a variety of clinical conditions that contribute to folate or folic acid deficiency. A deficiency of folate may occur in situations where there is an increased demand for folate, such as during pregnancy, lactation, infancy, malignancy (where there is increased cell turnover), infection (due to an immunoproliferative response), or chronic hemolytic anaemia (due to increased hematopoiesis).
Conditions associated with malabsorption, such as coeliac disease, also place patients at a higher risk for folate deficiency. Metabolism of folate may also be impaired due to various folic acid antagonist drugs, and patients with severe liver or kidney disease may have increased excretion of folate. Furthermore, despite widespread fortification of foods with folic acid, deficiency still occurs in situations where there is inadequate ingestion or poor nutrition.
Either a serum or Red Blood Cell folate test may be used to help detect a deficiency.
Symptoms of a folate deficiency can include:

Active-B12 is an innovative method for assessing Vitamin B12 status and offers improved accuracy, sensitivity and specificity over current laboratory methods. 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.
