Calcium is not just the foundation of our bones and teeth. It plays a role in heart function, nerve impulse transmission, muscle contraction, and even blood clotting. Its level in the body changes under the influence of nutrition, hormonal balance, and kidney and liver function. That is why doctors often recommend taking blood test for calcium<\/strong>, to check whether the body is getting enough of this mineral and whether it is being absorbed properly.<\/p>\n

What does a calcium test show?<\/strong><\/h2>\n

The analysis helps to assess mineral metabolism and identify possible disorders in the functioning of the skeletal system, heart, kidneys or thyroid gland. In the blood, calcium exists in two forms: bound (with proteins, mainly albumin) and ionized (the active form that participates in biological processes). It is ionized calcium that is the most informative indicator.<\/p>\n

When the doctor prescribes the test<\/strong><\/h2>\n

It is recommended to take the test in the following conditions: frequent cramps, numbness of the limbs, suspected osteoporosis, bone pain, kidney or liver pathology, thyroid problems. It is also necessary in case of suspected tumor processes, because some types of cancer can increase the level of calcium in the blood.<\/p>\n

How to prepare for the study<\/strong><\/h2>\n

Blood for calcium is taken in the morning on an empty stomach. During the day, it is worth giving up dairy products in large quantities and calcium supplements to avoid false results. If you are taking medications that affect calcium metabolism (glucocorticoids, diuretics, hormones), you should inform your doctor about this.<\/p>\n

According to Mayo Clinic<\/strong>, normal values are as follows:<\/p>\n
