Phosphate, Random details
What Phosphate, Random shows
This test measures phosphate in a single urine sample collected at any time, rather than over 24 hours. Phosphate is a mineral needed for bones and energy, and your kidneys control its blood level by adjusting how much they let out in urine. A random sample gives a quick snapshot of phosphate excretion, for example when looking at kidney handling of phosphate or causes of abnormal blood phosphate. Higher levels can reflect recent diet, parathyroid activity or kidney phosphate loss; lower levels can reflect low intake. Because urine concentration varies through the day, a random result is often compared with creatinine or confirmed with a 24-hour collection.
Tests that include Phosphate, Random
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.
- Phosphate, Random Measures phosphate in a single random urine sample, giving a snapshot of how much phosphate your kidneys are excreting.
