Notice
Laboratory test results must always be interpreted in the context of the patient’s medical history, clinical condition, and the results of other laboratory and diagnostic tests. Deviations from normal values are not sufficient on their own to establish a diagnosis, and values within the normal range do not always mean that a disease is absent. It is advisable to consult a doctor about the results.

What interests you about the Calcium test?
What can cause an increase in blood calcium levels?
The cause of a higher blood calcium level is its increased leaching from the bones. This occurs due to an excess of parathyroid hormone released by the parathyroid glands. Other causes include some types of cancer (myeloma, bone metastases, lung, esophageal, head and neck, kidney, ovarian, bladder cancer). An excess of vitamin D is also associated with a higher blood calcium level.
The cause may also be:
- increased bone turnover due to immobilization,
- higher levels of thyroid hormones,
- overdose of vitamin A,
- insufficient adrenal function.
It may also be due to excessive absorption of calcium in the intestine, the intake of certain medications causing insufficient excretion of calcium by the kidneys, or dehydration, while the amount of calcium in the blood is not actually increased. [1]
How does an elevated blood calcium level manifest itself?
Symptoms of an elevated blood calcium level vary depending on the cause and duration, degree of increase and speed of onset. A mildly elevated calcium level is practically symptomless or manifests itself only with non-specific symptoms.
The most common symptoms are disorders of the nervous system (fatigue, muscle weakness, lethargy, cramps, confusion, delirium) and digestive tract functions (nausea, anorexia, vomiting, abdominal pain and constipation). The kidneys are often affected, due to the increased calcium concentration there is excessive urination and subsequently thirst. Kidney stones can also form and obstruction of the hollow system and renal failure can occur. Cardiovascular symptoms may include rhythm disturbances (slowing or accelerating) or conduction disturbances such as conduction block. High levels can lead to coma, low blood pressure, kidney or heart failure, or the formation of clots in the veins. [2]
How does low blood calcium levels manifest?
People with mild hypocalcemia usually have no symptoms. A very important factor is the speed of hypocalcemia. The faster the low blood calcium levels develop, the more obvious the symptoms are. The most dramatic manifestation is the so-called tetanic (muscle) spasms, most often affecting the larynx or bronchi.
Slowed heart rate, low blood pressure, heart failure and small or large epileptic seizures may also occur. Symptoms depend on the severity of hypocalcemia. Mild hypocalcemia may be asymptomatic, or may only manifest itself as tingling around the mouth and in the limbs. If it lasts longer, depression, memory loss or hallucinations may develop. Chronic hypocalcemia is also manifested by dry skin, brittle nails and poor hair quality. [3]
What is calcium used for?
The body needs calcium to move muscles (contraction of skeletal and cardiac muscles) and to transmit messages between the brain and the rest of the body. Calcium also helps blood clot and release hormones that affect most processes in the body. Calcium works closely with vitamin D, which helps it be absorbed.[1]
Which hormone increases blood calcium levels?
Blood calcium levels, absorption, and excretion are controlled by parathyroid hormone, calcitonin, and calcitriol (a hormone derived from vitamin D). Parathyroid hormone (PTH) is a hormone produced and released by the parathyroid glands that increases blood calcium levels. It also helps control phosphorus and vitamin D levels in the blood and bones. The antagonist of PTH is calcitonin, which lowers blood calcium levels.[4]
