Ca | Calcium

Calcium is the most abundant mineral in the body, with 99 percent found in bones, while the remaining calcium is distributed among various tissues and extracellular fluids, where it plays a crucial role in many vital processes.

Among the calcium functions unrelated to the skeletal system are participation in blood clotting, neuromuscular impulse transmission, skeletal and cardiac muscle excitability, enzyme activation, and maintaining cell membrane integrity and permeability. Calcium metabolism processes in the body are associated with parathyroid hormone (PTH), calcitonin, and vitamin D.

Increased serum calcium concentration may also be observed in cases of multiple myeloma or other cancers. Hypocalcemia can be observed, for example, in hypoparathyroidism, nephrosis, or pancreatitis.

Recommendations:

• It is recommended to perform prophylactic testing once a year; for disease diagnostics and treatment monitoring, it is performed periodically as per doctor's instructions.
• Test results are influenced by medications and diet (consumption of dietary supplements).
• For test sampling, it is necessary to arrive fasting for 12 hours, and 2-3 days before the test, avoid supplements with calcium and vitamin D.
