Clinical Utilities 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. Measurements of urinary phosphorus generally reflects dietary intake; hence, day-to-day excretion may show considerable variation.

Collection Instructions
  Random urine: 10 mL random urine, adjust pH to < 3.0 with 6N HCL
before aliquoting for phosphate testing. Transport at room
temperature.
Unpreserved urine: Keep urine refrigerated during and after
collection and send frozen.
Transport at room temperature.
