Studying Phosphorus Metabolism

Completed

Conditions studied: Phosphorus Metabolism

In brief

Phosphorus and phosphate irons play critical roles in bone structure and essential cellular functions. The purpose of this study is to learn more about the factors and hormones that regulate phosphorus in the body by collecting blood and urine samples from patients with disorders of phosphate control. Both children and adults will be enrolled in this study. Researchers will collect blood and urine samples from participants on multiple occasions (2 to 6 times). Some blood specimens will be taken after an overnight fast and participants may be asked to collect all their urine during a 24-hour period. Researchers will analyze these blood and urine samples to better understanding how the body handles phosphorus.
