A new specific assay for urinary creatinine.

چکیده
A new specific assay for urinary creatinine is described. The procedure is based on the separationof creatinine from other urinary componentsby Sephadexgel filtration, and subsequentmeasurementof the compoundat 235 nm against a phosphatebuffer blank. No interference by other substances has been encountered. The standard deviations in a series of assaysusing standard solutions are less than 2%, and the recoveryof added known amounts of creatinine from urine is excellent. The method has been found satisfactory for simultaneousdetermination of creatinine and hippuric acid in urine.

Paired measurement of urinary creatinine in neonates based on a Jaffe and an enzymatic IDMS-traceable assay
BACKGROUND Urinary creatinine can be quantified by Jaffe or enzymatic assays and is commonly used as denominator of urinary excretion of electrolytes or protein. Paired analysis in pediatric and adult samples documented inter-assay differences (up to 80%). We verified the interchangeability of two IDMS-traceable assays (Jaffe and enzymatic) for neonatal urine and report on neonatal urinary crea...
متن کاملTandem mass spectrometry measurements of creatinine in mouse plasma and urine for determining glomerular filtration rate.
Endogenous creatinine clearance (Ccr) is widely accepted as an estimate of glomerular filtration rate (GFR), the best overall biomarker of kidney function. However, current common methods of measuring creatinine are not sensitive enough for mouse plasma. Accordingly, we here report a new method of measuring creatinine by liquid chromatography tandem mass spectrometry (LC-MS/MS) using deuterated...
متن کاملMeasurement of urinary retinol-binding protein by enzyme-linked immunosorbent assay, and its application to detection of tubular proteinuria.
An enzyme-linked immunosorbent assay (ELISA) for urinary retinol-binding protein (RBP) has been developed and compared with urinary beta 2-microglobulin for the detection of tubular proteinuria. The assay has a working range of 10 to 250 micrograms of RBP per liter of urine. The within-assay CV was 3.2-7.1%, the between-assay CV 12.5%. A control population of 118 male subjects gave a geometric ...
متن کاملAssociation of Urinary Lipocalin-2 with Lupus Nephritis
Objective(s): Lupus nephritis (LN) is the main cause of mortality and disability in systemic lupus erythematosus (SLE) patients. Therefore, utilizing a reliable and non-invasive method for serial measurements of renal function seems to be necessary. The aim of this study was to evaluate the role of urinary lipocalin-2 as a biomarker of renal involvement in SLE patients. Materi...
متن کاملUrinary neutrophil gelatinase-associated lipocalin as a marker of acute kidney injury after orthotopic liver transplantation.
BACKGROUND Urinary neutrophil gelatinase-associated lipocalin (NGAL) is a novel, sensitive and specific biomarker that is rapidly released after kidney injury. It predicts acute kidney injury (AKI) in multiple clinical scenarios. We hypothesized that urinary NGAL can predict AKI after liver transplantation. METHODS Urine was collected in 92 patients undergoing liver transplantation (18 living...
