Persistently increased protein excretion is usually a marker of kidney damage. Quantifying protein in urine is commonly used in the diagnosis of kidney diseases, detection of treatment effects and evaluation of prognosis.
Urinary protein creatinine ratio in spot urine (UPCR) can be used as an alternative to urine protein excretion in 24 hrs collections. UPCR in first morning urine samples is better than that in random specimens, especially for outpatients.
