What is this test?
The 24-hour predicted protein test estimates how much protein your kidneys are leaking into your urine over a 24-hour period. Normally, healthy kidneys filter waste from your blood while keeping important proteins in your body. When kidneys are damaged, they may allow proteins like albumin to leak into urine.
How does the test work?
Instead of collecting all urine for 24 hours, this test uses a single random urine sample. It measures both protein and creatinine (a waste product) in your urine and calculates a ratio. This protein-to-creatinine ratio (PCR) is then used to estimate your 24-hour protein excretion. Creatinine is excreted at a relatively constant rate, making it a useful reference point.
Why is this test important?
Protein in urine (proteinuria) is an important sign of kidney damage. Early detection of kidney problems allows for better management and can prevent further damage. This test is commonly used to monitor patients with diabetes, high blood pressure, or known kidney disease.
How to prepare for the test
No special preparation is usually needed for this test. You may be asked to avoid certain medications or strenuous exercise before the test, as these can affect results. Follow any specific instructions from your healthcare provider.
Reference range
Normal: <150 mg/24h or <150 mg/g creatinine; Abnormal: >150 mg/24h indicates proteinuriaN/A
No specific fasting required. Collect random urine sample preferably in morning. Avoid vigorous exercise 24 hours prior to collection as it may cause transient proteinuria. Inform clinician of any recent infections or medications that may affect kidney function.
