The University of Pennsylvania Smell Identification Test (SIT) is the most cited olfactory test in the literature because it is easy to perform and there is high test-retest reliability. There were no standardized olfaction values in a normal Brazilian population.
To measure the SIT score in a group of Brazilians, and to assess the level of difficulty when implementing the test.
A cross-sectional study.
The SIT was applied in 25 Brazilian volunteers of various income levels who presented no olfactory complaints. Following the test, subjects answered a questionnaire with a visual analog scale (VAS) for the level of difficulty.
The mean in the sample of Brazilians was 32.5 (SD: 3.48) our of 40; this is below what is considered normal for US citizens. The level of difficulty was on average 26 mm (SD: 24.68) in the VAS, but it trended towards easy; 4(16%) participants did not recognize some of the odors under 'alternatives'.
In this pilot study, there was evidence of good test applicability; the score of the sample of Brazilians was just below normosmia. Further studies are needed to confirm the existence of differences between people of different income levels.
宾夕法尼亚大学嗅觉识别测试（SIT）是文献中被引用最多的嗅觉测试，因为它易于操作，且具有较高的重测信度。在正常的巴西人群中，没有标准化的嗅觉值。
测量一组巴西人的 SIT 分数，并评估实施测试的难度水平。
一项横断面研究。
SIT 应用于 25 名不同收入水平的无嗅觉投诉的巴西志愿者。测试后，受试者使用视觉模拟量表（VAS）回答问卷，评估难度水平。
巴西人的平均分数为 32.5（SD：3.48），低于美国公民的正常水平。VAS 中的平均难度水平为 26 毫米（SD：24.68），但趋于简单；4（16%）名参与者无法识别“替代”选项下的某些气味。
在这项初步研究中，有证据表明测试适用性良好；巴西人的样本分数略低于正常水平。需要进一步研究以确认不同收入水平人群之间是否存在差异。
