Iron – Values are a measure of the supply in the blood. It is not the same as the anemia-screening test, although low values in this test may help explain anemia. Iron levels decrease during the day.
Calcium – screens for range of conditions relating to the bones, heart, nerves, kidneys, and teeth. Blood calcium levels do not directly tell how much calcium is in the bones, but rather, how much total calcium or ionized calcium is circulating in the blood.
Phosphorus: A mineral found in bone. Abnormal levels are seen with kidney, bone and parathyroid disease. Low levels seen with excessive antacid use, gout, insulin therapy, and vitamin D deficiency.
