Phosphorus analysis in urine, using atomic absorption spectrophotometry (Flame and GFA mode), is a test used to measure phosphorus levels in urine. Phosphorus is an important element in the body, playing a key role in bone health and metabolism. A urine sample is collected and analyzed using spectrophotometry, which allows for accurate detection of phosphorus concentration. This test helps doctors assess kidney function, monitor metabolic disorders, and track conditions such as chronic kidney disease or thyroid disorders. It may be recommended in certain cases, such as when symptoms suggest phosphorus imbalances or after dietary changes. The results provide valuable insights into the body's mineral balance and help determine the need for any therapeutic interventions.
