What is the Phosphorus Test?
Serum Phosphorus works alongside calcium for bone formation and energy metabolism. Phosphorus levels are regulated by the kidneys and parathyroid hormone. Abnormal phosphorus often indicates kidney disease, parathyroid disorders, or vitamin D abnormalities.
Why Should You Take This Test?
High phosphorus in CKD accelerates vascular calcification and bone disease. Low phosphorus occurs in refeeding and some genetic disorders.
Who Should Get Tested?
Kidney Disease Patients
Kidneys regulate phosphorus — disease causes accumulation.
Bone Disorders
Phosphorus is essential for bone mineralization.
Abnormal Calcium Levels
Calcium and phosphorus are inversely related.
