Clinical Significance
Key test for assessing kidney health by estimating daily protein loss from a single urine sample, indicating potential kidney damage (proteinuria) from diabetes, high blood pressure, or other diseases, and helping to diagnize and monitor conditions like chronic kidney disease (CKD) and preeclampsia, offering a convenient alternative to 24-hour collections. An elevated ratio signals protein leakage, prompting further investigation, with higher numbers indicating more severe loss, while a normal ratio (under ~0.2) suggests healthy kidney filtration, though temporary spikes can occur with stress or exercise.
