Two types of urine protein dipsticks and the sulfosalicylic acid method were compared for their accuracy and specificity, with use of urine samples supplemented with various proteins. Dipsticks yield accurate results when the protein under consideration is restricted to albumin; the sulfosalicylic acid method accurately determines many kinds of proteins in addition to albumin. Detergents affect each of the methods, but changes in salt concentration only affect results by dipstick procedures. Dipsticks, which are based on the protein-error principle for indicators, are subject to some of the conditions that apply to the bromcresol green method for serum albumin determination.
使用添加了各种蛋白质的尿液样本，比较了两种尿蛋白试纸和磺基水杨酸法的准确性和特异性。当所检测的蛋白质仅限于白蛋白时，试纸能得出准确结果；磺基水杨酸法除了能准确测定白蛋白外，还能测定多种蛋白质。去污剂会影响这两种方法，但盐浓度的变化仅会影响试纸法的检测结果。基于蛋白质误差指示剂原理的试纸，会受到一些适用于血清白蛋白测定的溴甲酚绿法的条件限制。
