Urine protein/creatinine ratio is a widely used initial method to estimate daily protein excretion in urine. [1] [2] [3] Since the diagnosis and management of proteinuric renal diseases and the staging of chronic kidney disease depend on accurate identification and quantitation of proteinuria, [4] [1] the implementation of the 24-hour urine collection is the most accurate procedure in practice ...
This is termed the protein/creatinine ratio. The 2005 UK Chronic Kidney Disease guidelines state that protein/creatinine ratio is a better test than 24-hour urinary protein measurement. Proteinuria is defined as a protein/creatinine ratio greater than 45 mg/mmol (which is equivalent to albumin/creatinine ratio of greater than 30 mg/mmol or ...
Abnormal kidney function may cause too much or too little urine to be produced. The ability of the kidneys to filter protein is often measured, as urine albumin or urine protein levels, [2] measured either at a single instance or, because of variation throughout the day, as 24-hour urine tests.

Trace levels of protein in the urine can be normal, [60] but high levels (proteinuria) can indicate kidney disease. [45] Most cases of proteinuria are caused by increased levels of albumin , [ 61 ] which test strips can detect relatively well; but they are markedly less sensitive to other proteins, such as Bence-Jones protein , [ 62 ] which may ...
Urine analysis, urine cytology, complement activity, urine culture, and serological studies can help differentiate orthostatic albuminuria from other causes of proteinuria. Recumbent and upright urine protein to creatinine ratio is often used as a screening test. 24-hour split urine testing is often tested. [10]
A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system , and specimens are easy to obtain. [ 1 ]
UUN is determined from 24-hour urine collection. Along with UUN, values for BUN, protein content of diet, enteral or parenteral nutrition, and notable outputs other than urine (gastric residual, fistula output, drainages) are needed to calculate nitrogen balance. Nitrogen Balance = Protein intake/6.25- (UN + 4*) * For average loss via sweat and ...
