Tests: Your UIBC is a measure of your unsaturated iron binding capacity. Range for this test is 120 – 470 µg/dL. In conjunction with a serum Iron the test is valuable. Vitamin D levels effect calcium levels and other body processes. Supplemental vitamin D may help. Low folate levels can be associated with anemia too, but that is a macrocytic or big blood cell anemia where as iron deficiency is small
