[8] [20] Traditionally, dipstick protein tests would be quantified by measuring the total quantity of protein in a 24-hour urine collection test, and abnormal globulins by specific requests for protein electrophoresis. [3] [21] Trace results may be produced in response to excretion of Tamm–Horsfall mucoprotein.
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 ...

Proteinuria of greater than 3.5 g /24 h /1.73 m 2 (between 3 and 3.5 g/24 h /1.73 m 2 is considered to be proteinuria in the nephrotic range) or greater than 40 mg/h/m 2 in children. [9] [10] The ratio between urinary concentrations of albumin and creatinine can be used in the absence of a 24-hour urine test for total protein. This coefficient ...
Measuring the amount of protein in the urine helps to distinguish between different causes of proteinuria. [151] [152] Urine protein electrophoresis, which identifies and measures the proportions of different types of protein in the urine, may be used to investigate the cause of proteinuria [151] and to detect Bence-Jones protein. [153]
Urine cytology — cytopathological examination of cells in the urine, used to screen for cancer [21] Urine protein electrophoresis — classification and measurement of different proteins in the urine; used to help diagnose monoclonal gammopathies [22] Urine organic acids, urine amino acids — used to test for some inborn errors of metabolism [8]
Increased levels of protein in the urine, proteinuria, can be measured with a urine dipstick test. Three different tests may be used to measure calcium levels in urine, 24-hour urine tests, blood tests, and genetic tests. Measuring calcium levels can also be done using an oral calcium tolerance test. [24]
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]
