Why is this Test Done?
An ionized calcium blood test may be performed for a number of reasons. Parathyroid disease or kidney disease are two of the primary reasons a patient may need to undergo this blood test. If a doctor suspects certain neurologic disorders, high or low calcium levels, thyroid disease, cancer, intestinal disease, or malnutrition this test may be done. Other reasons include a critically ill patient being administered intravenous fluids or blood transfusions, patients with low albumin and other low-protein abnormalities, and patients undergoing major surgery.
If a patient has high ionized calcium levels, they may experience fatigue, appetite loss, constipation, needing to urinate frequently, weakness, vomiting, abdominal pain, increased thirst, and vomiting.
If a patient has low ionized calcium levels, they may experience abdominal cramping, tingling fingers, and muscle cramping.
