This test measures the biologically active form of calcium (S-Calcium), also known as free calcium ions. The test is recommended for those who want a deeper understanding of their calcium levels to identify various medical conditions that can impact their health. In particular, the test is conducted when there is a suspicion of issues with the parathyroid glands, which regulate calcium regulation through the hormone parathormone or PTH, which can lead to hyperparathyroidism or hypoparathyroidism. The test can also be conducted when there is a suspicion of vitamin D deficiency, difficulties in calcium absorption (malabsorption), or kidney problems such as uremia, which can affect the calcium ions in your blood.
Reference Range in Analysis
The normal reference range in the analysis of calcium ions in the blood is 1.15 - 1.35 mmol/L.
