Phosphorus, Inorganic, Serum
Order Code:
PHOS
Test Summary
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.
