Measurement of tubular reabsorption of phosphate is most useful in diagnosing diseases affecting which gland?

Explanation:
Phosphate handling in the kidney is directly controlled by parathyroid hormone. PTH lowers the reabsorption of phosphate in the proximal tubule, causing more phosphate to be excreted in urine. Because of this direct link, measuring tubular reabsorption of phosphate serves as a useful clue to parathyroid function: high PTH lowers the reabsorption (lower TRP), while low PTH raises it. This makes the test particularly informative for diseases of the parathyroid gland, rather than the liver, adrenal, or thyroid glands, whose primary roles don’t regulate renal phosphate reabsorption as directly.
