Simple automated method for urinary creatinine estimation

Simple Automated Method for Urinary Creatinine Estimation.

The increasing numbers of investigations into metabolic processes have necessitated the adaptation to automated principles of a method whereby the efficacy of quantitative urine collections can be tested. The estimation of creatinine (creatine anhydride) for this purpose has several aJvantages over other methods which have been used. Creatinine excretion is fairly constant from day to day (Foli...

Simplified HPLC method for urinary and circulating creatinine.

HPLC with various detection methods, including ultraviolet absorbance, is frequently used to separate and measure creatinine and creatine in serum, plasma, and urine. Current HPLC and other analytical methods for the measurement of creatinine, including capillary electrophoresis and gas chromatography–mass spectrometry, have been reviewed recently (1 ). In 1990, Paroni et al. (2 ) reported a ca...

Simple, rapid, kinetic method for serum creatinine measurement.

Test for mucopolysaccharidoses: simple method for quantitative estimation of urinary glycosaminoglycans.

A simple method is described for measurement of urinary glycosaminoglycans (GAG) in normal and pathological urine: a fixed fraction of the 24-h urine is passed over a small plug of ECTEOLA-modified cellulose and the GAG are eluted with a few milliliters of NaCI solution (3 mol/liter) and measured as hexuronic acid. Because results are compared for equal aliquots of complete 24-h urines, GAG are...

An Automated Method for Serum Magnesium Estimation.

An automated method for magnesium determination in serum is described using conventional AutoAnalyser equipment. The method gives results comparable with those obtained by the flame photometer. The method may prove particularly useful with subnormal serum magnesium levels.
