Comparison of the Diagnostic Accuracy of Three Com- Mercially Available Enzyme Immunoassays for Anti-p53

malabsorption could be a risk factor in the development of these diseases. Because bacterial metabolism alters folic acid status and intestinal bacterial colonization is altered by nutritional factors and carbohydrate malabsorption syndromes, dietary measurements should not rely solely on folic acid supplementation but should also consider carbohydrate malabsorption syndromes, especially fructose malabsorption. It is suggested that fructose malabsorption be considered in the elderly with folic acid deficiency. Further studies will be necessary to compare not only folic acid concentrations but also homocysteine, vitamin B12, and hematological indices in patients with and without fructose malabsorption.
