The comparison of specific gravity values of 561 urine samples from TS meter and reagent strip was made. The data were divided into two groups: group 1-less than 2+ protein contained urine samples and group 2--equal or more than 2+ protein contained urine samples. The results revealed that the specific gravity values from both methods in both groups were statistically different (p less than 0.01) but they were correlated at r = 0.84 (p less than 0.001) and r = 0.73 (p less than 0.001) in group 1 and group 2, respectively. It was concluded that the reagent strip is suitable for use as a screening test but it should not be considered when precise measurement is necessary.
对561份尿液样本用TS计和试带法进行了比重值比较。数据分为两组：第1组——蛋白质含量低于2+的尿液样本，第2组——蛋白质含量等于或高于2+的尿液样本。结果显示，两组中两种方法的比重值在统计学上均有差异（p<0.01），但第1组和第2组中两种方法的比重值分别在r = 0.84（p<0.001）和r = 0.73（p<0.001）水平上具有相关性。结论是，试带法适用于筛查，但在需要精确测量时不应采用。
