Blood calcium level - Calcium (Ca), Serum

🦴 Calcium analysis in the blood This analysis measures the amount of calcium in the blood, and it is an essential element for the health of bones and teeth, and it also has an important role in muscle function, heartbeat, and blood clotting. If the level is low, it may be due to: deficiency in vitamin D, or problems with the parathyroid gland, or poor nutrition. If it is high, it may indicate: increased parathyroid activity, or kidney problems, or taking calcium supplements excessively. 🩺 Why does the doctor request the analysis? Usually with electrolyte and mineral tests or if there is muscle fatigue, cramps, or bone problems. 💡 Advice: It is preferable to do the analysis while fasting for 6 to 8 hours, and inform the doctor if you are using calcium or vitamin D supplements because they may alter the result.
