An olfactory function test developed by the Connecticut Chemosensory Clinical Research Center (CCCRC) was administered to 65 normal subjects to determine its ability to identify normosmic subjects. The CCCRC test categorizes individuals into five distinct levels of olfactory functioning according to composite score ranges derived from odor identification and butanol threshold subtests. These categories are: normosmic (normal); mildly, moderately, and severely hyposmic (impaired functioning); and anosmic (no sensation). Comparing score distributions from CCCRC with ours revealed that a greater percentage of our subjects were categorized as hyposmic because of higher butanol thresholds. The butanol threshold subtest was studied further to determine test-retest reliability and normal day-to-day variability in scores. Norms are the basis for interpreting test scores and are important in diagnosing and treating smell disorders.
康涅狄格化学感觉临床研究中心（CCCRC）开发的一项嗅觉功能测试应用于65名正常受试者，以确定其识别嗅觉正常受试者的能力。CCCRC测试根据气味识别和丁醇阈值子测试得出的综合分数范围，将个体分为五个不同的嗅觉功能水平类别。这些类别为：嗅觉正常（正常）；轻度、中度和重度嗅觉减退（功能受损）；以及嗅觉缺失（无感觉）。将CCCRC的分数分布与我们的进行比较后发现，由于丁醇阈值较高，我们的受试者中被归类为嗅觉减退的比例更高。对丁醇阈值子测试进行了进一步研究，以确定测试 - 再测试的可靠性以及分数的日常正常变异性。标准是解释测试分数的基础，在嗅觉障碍的诊断和治疗中很重要。
