| A | B |
|---|
| Hyperparathyroidism | decreased blood PO4; increased blood Ca |
| Hypoparathyroidism | increased blood PO4, decreased blood Ca |
| PTH | increases calcium tubular reabsorption, decreases phosphorus tubular reabsorption |
| Calcitonin | decreases tubular reabsorption and bone resorption for calcium and phosphorus |
| Cholecalciferol | increases tubular reabsorption and intestinal and bone resorption of both calcium and phosphorus |
| Hypomagnesemia | Similar to hypocalcemia (tetany) |
| Menkes' kinky hair syndrome | genetic defect of copper absorption |
| Wilson's disease | decrease in synthesis of normal ceruloplasmin |
| Calcium measurement | o-cresol-pthalein complexone |
| Hypocalcemia | tetany |
| Iron Deficiency anemia | decreased serum iron, transferrin saturation, and serum ferritin; increased TIBC |
| Ineffective erythropoiesis | increased serum iron, transferrin saturation, serum ferritin; unchanged TIBC |
| Iron overload (hemochromatosis) | increased serum iron, transferrin saturation, serum ferritin; decreased TIBC |
| Liver disease | increased serum iron, TIBC, transferrin saturation, serum ferritin |
| Serum iron reference range | 40-160 ug/dL |
| TIBC reference range | 250-400 ug/dL |
| Serum Ferritin male ref. range | 20-300 ug/L |
| serum ferritin female ref. range | 10-120 ug/L |
| TIBC | indirect method of measuring serum transferrin |
