The Phosphorus test helps diagnose and manage conditions related to phosphorus imbalance. Low levels of phosphorus can lead to symptoms such as muscle weakness, bone pain, and fatigue, often associated with conditions like malnutrition or chronic alcoholism. High levels of phosphorus can indicate kidney dysfunction and may present symptoms such as itching, joint pain, and soft tissue calcification. The test is essential for evaluating mineral balance, bone health, and kidney function, guiding appropriate treatment and dietary adjustments.
