Discover the importance of phosphorus in your body with our Phosphorus Blood Test. This test measures the level of phosphorus in your blood, a prevalent mineral found in the food we consume and also present in our teeth and bones. Abnormal phosphorus levels can indicate various health conditions, such as kidney disorders and uncontrolled diabetes. The test is performed using a blood sample drawn from a vein in your arm or hand, with results expressed in milligrams per deciliter (mg/dL).
