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.

Collect urine with 25 mL of 6N HCL to maintain a pH below 3. Do not
include first morning specimen; collect all subsequent voidings.
The last sample collected should be the first morning specimen
voided the following morning at the same time as the previous
morning's first voiding. Specify 24-hour total volume on container
and test requisition. Transport room temperature.
