The Schilling test is performed by administering radioactive cobalamin and then measuring its excretion in the urine. Low urinary excretion is significant for PA. It does not involve the measurement of serum ferritin and total iron-binding capacity.The Schilling test is performed by administering radioactive cobalamin and then measuring its excretion in the urine. Low urinary excretion is significant for PA. It does not involve the administration of folate.REF:p. 503
