Phosphorus in the blood - Phosphorus (PO₄), Serum

🧪 Phosphorus analysis in blood This analysis measures the percentage of phosphorus (or phosphate) in the blood, and it is an important mineral that helps in building bones and teeth, and works with calcium and vitamin D to maintain bone strength and energy balance in the body. If the percentage is high, it may be caused by kidney problems or excess vitamin D. If it is low, it may indicate malnutrition or vitamin D deficiency or absorption problems. 🩺 Why does the doctor request the analysis? Usually requested with calcium tests or kidney function tests, especially if there is general fatigue or problems in bones or muscles. 💡 Advice: It is preferable to do the analysis while fasting for 6 to 8 hours, and inform the doctor if you are using medications or supplements containing calcium or vitamin D because they may affect the result.
