Phosphorus determination in urine

What is it? 

This is a laboratory test that indicates the amount of phosphorus in urine. Phosphorus is important for bone structure, energy metabolism, and cell function. 

When is it recommended? 
It is prescribed when metabolic disorders, kidney diseases, endocrine system problems (especially parathyroid hormone activity) are suspected, as well as for assessing phosphorus balance together with calcium. 

What can the results indicate? 

• Increased phosphorus in urine – may indicate an excess of vitamin D, hyperparathyroidism, or bone degradation. 
• Decreased – possible hypoparathyroidism or vitamin D deficiency.
