The absorptive capacities of 4 commercially available tear test strips were determined and compared with 5-mm X 40-mm strips of #41 filter paper. Significant differences in the absorption of water over a given time interval were found in 3 of the groups tested. Major inconsistencies were found only within 1 lot of tear test strips from a single manufacturer. Tear test strips from this lot consisted of 2 distinct populations that were distinguishable by transillumination. Strips with widely spaced horizontal lines had the same absorptive capacity as the filter paper, whereas those with fine lines consistently absorbed less water. The clinical importance of this discrepancy was verified by comparing measurements of tear production in 6 normal dogs.
测定了4种市售泪液试纸条的吸收能力，并与5毫米×40毫米的#41滤纸进行了比较。在测试的3组中，发现给定时间间隔内水的吸收存在显著差异。仅在来自单个制造商的一批泪液试纸条中发现了主要的不一致性。这批泪液试纸条由2个不同的群体组成，通过透照法可以区分。水平线条间距宽的试纸条与滤纸具有相同的吸收能力，而线条细的试纸条始终吸收较少的水。通过比较6只正常犬的泪液分泌测量值，证实了这种差异的临床重要性。
