Comparison of spot urine protein creatinine ratio with 24 hour urine protein for estimation of proteinuria.
The objective of our study was to evaluate and standardise the method of spot (random) urine protein creatinine ratio (UP/C) for estimation of proteinuria. The study contained 241 study participants in a tertiary care hospital inclusive of 208 cases and 33 normal volunteers. The 24 hour urine protein estimation was done on 24 hour urine samples and UP/C ratio was calculated on random urine samp...
متن کاملA comparison of spot urine protein-creatinine ratio with 24-hour urine protein excretion in women with preeclampsia.
INTRODUCTION Proteinuria is an important diagnostic component of preeclampsia. We prospectively compared the results of spot urine protein-creatinine (P/C) ratio with 24-hour urine protein excretion in women with preeclampsia. MATERIALS AND METHODS A total of 81 pregnant women with preeclampsia were prospectively studied for proteinuria. Urine P/C ratio was determined in a spot mid-stream uri...
متن کاملA New Commercial Method for the Enzymatic Determination of Creatinine in Serum and Urine
biotimdase-deficient specimen in the autosampler. A sample cup containing phosphate buffer should be inserted between each sample suspected of having deficient or very low activity. Interfering substances such as sulfonamides, if present in a sample, can cause color development, such that a biotimdase-deficient specimen could exhibit color corresponding to normal activity and a normal specimen ...
متن کاملDetermination of creatinine in serum and urine by a rapid liquid-chromatographic method.
We describe an HPLC ion-pair procedure for rapid and specific evaluation of creatinine in serum and urine. We used a 15 cm X 4.6 mm ODS column with a 50/50 (by vol) mixture of sodium decanesulfonic acid (10 mmol/L, pH 3.2) and methanol and measured absorbance at 236 nm. Serum (100 microL) or 30-fold-diluted urine (100 microL) was added to 400 microL of acetone. After centrifugation, the superna...
متن کاملA new commercial method for the enzymatic determination of creatinine in serum and urine evaluated: comparison with a kinetic Jaffé method and isotope dilution-mass spectrometry.
We evaluated a new, simple, enzymatic kinetic method from Wako Chemicals GmbH in comparison with a kinetic Jaffé method by using isotope dilution-mass spectrometry (ID-MS) as a reference method. An ID-MS-calibrated serum standard was used. Both the enzymatic and the Jaffé method correlated well with ID-MS, except for sera with high concentrations of bilirubin. Ethyl acetoacetate, acetone, and g...
