Phosphorus determination in urine

What is it? 

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

When is it recommended? 
It is prescribed if metabolic disorders, kidney diseases, or endocrine system problems (especially parathyroid hormone activity) are suspected, as well as to assess phosphorus balance in conjunction with calcium. 

What can the results mean? 

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