A serum calcium blood test measures the total calcium in your blood. There are several different forms of calcium in your blood. These include ionized calcium, calcium bound to other minerals called anions, and calcium bound to proteins like albumin. Ionized calcium, also known as free calcium, is the most active form.

What is ionised calcium?
Ionized calcium is calcium in your blood that is not attached to proteins. It is also called free calcium. All cells need calcium in order to work. Calcium helps build strong bones and teeth. It is important for heart function.
What percentage of serum calcium is ionized?
Serum (plasma) calcium exists in 3 distinct forms. Approximately 15% is complexed calcium bound to organic and inorganic anions, 40% is bound to albumin, and the remaining 45% circulates as free ionized calcium. Calcium is essential for bone mineralization, neuromuscular function, and secretion of hormones and enzymes.
When do you use ionized calcium?
Specifically, reports suggest that ionized calcium is superior in identifying calcium disturbances in patients receiving transfusions with citrated blood; in critically ill patients; and in patients with the late stages of chronic kidney disease (CKD), hyperparathyroidism, and hypercalcemia of malignancy.
What is ionized calcium normal range?
The parathyroid glands can be thought of as the “calcium thermostat” of the body.
| Lab | Normal range (conventional units) |
|---|---|
| Calcium (serum) | 8.6-10.3 mg/dL |
| Calcium (ionized) | 4.4-5.2 mg/dL |
| PTH (parathyroid hormone) | 11-51 pg/mL |
| Creatinine (marker of kidney function) | 0.6-1.3 mg/dL |
Does fasting affect calcium levels?
Fasting total calcium levels may be sufficient for monitoring progress. However, for diagnostic purposes, fasting ionized calcium levels should be used. Therefore, for an isolated high total calcium level, we recommend obtaining a repeat fasting total and ionized calcium measurement before further investigations.
How do you fix calcium?
Thus, the calcium level should be corrected in patients with low serum albumin levels, using the following formula: Corrected calcium (mg/dL) = measured total Ca (mg/dL) + 0.8 (4.0 - serum albumin [g/dL]), where 4.0 represents the average albumin level.
How is high ionized calcium treated?
This type of drug can help control overactive parathyroid glands. Cinacalcet (Sensipar) has been approved for managing hypercalcemia. Bisphosphonates. Intravenous osteoporosis drugs, which can quickly lower calcium levels, are often used to treat hypercalcemia due to cancer.
What is considered high ionized calcium?
Adults should generally have calcium levels that are "in the 9s" in mg/dl. Most labs will give a normal calcium range from about 8.8 to 10.5 mg/dl, but this is not correcting for age. A value of 10.5 in a teenager is perfectly normal, but 10.5 in adult over age 35 is too high – this is hypercalcemia.
Which range is the normal concentration of ionized calcium in human blood quizlet?
-The normal concentration of calcium in human plasma is between 8.4 and 10.2 mg/dl. 50% as free ionized (Ca2+). > This is the biologically ACTIVE form of calcium.
What causes low ionized calcium?
In hypocalcemia, the calcium level in blood is too low. A low calcium level may result from a problem with the parathyroid glands, as well as from diet, kidney disorders, or certain drugs.
Why is ionized calcium low sepsis?
Our results show that hypocalcemia during sepsis is multifactorial in origin and may result from acquired parathyroid gland insufficiency, impaired renal la-hydroxylation of vitamin D, vitamin D deficiency, or impaired tissue sensitivity to the action of vitamin D.
Is fasting required for calcium test?
Current practices do not require fasting. You may be instructed to stop taking certain medications, such as lithium, antacids, diuretics, and vitamin D supplements, among others, to ensure the most accurate test results.
