What is this test?
This urine test estimates the amount of alpha phosphate in a urine specimen. A calculated mass concentration adjusts the measured amount to account for the volume of urine collected.
Why might I need this test?
A urine phosphate measurement may be used to evaluate how the kidneys handle phosphate or to investigate changes in calcium and phosphate balance. Your clinician will decide whether this specific test is appropriate for your symptoms or medical history.
How is the test performed?
A urine sample is collected and analyzed in the laboratory. The result is generally reported as a mass concentration, meaning the amount of the substance relative to the amount of urine collected.
How do I prepare for the test?
Follow the collection instructions provided by your laboratory. Depending on the test, you may be asked to provide a single urine specimen or all urine collected over a specified period, commonly 24 hours.
Reference range
Adult: 44-147 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A higher or lower urine phosphate result may reflect changes in dietary intake, hydration, kidney function, or hormonal regulation of phosphate and calcium. Medication use and conditions affecting bone, kidney, or parathyroid function can also influence the result. The value should be interpreted with other laboratory findings by your clinician rather than on its own.
Short name
Urine alpha phosphate
