About the test

Phosphorus is present in many foods, with a mean intake of approximately 1500 mg per day for adult males and about 1000 mg per day for adult females. Absorbed phosphate, under the influence of parathyroid hormone, is readily excreted in the kidney. Measurement of urinary phosphorus generally reflects dietary intake; hence, day-to-day excretion may show considerable variation.
