Selectivity of proteinuria as determined by high pressure liquid chromatography.
The methods used for measurement of the selectivity of glomerular filtration are usually long and tedious. We report the use of protein HPLC for the determination of the selectivity index. When compared to the conventional procedure, this new approach gave 82% correlation. This method offers many advantages in clinical chemistry due to its rapidity, sensitivity and the objectivity of data analysis.
