Aim of the study was the development of a new screening test of olfaction with reusable diskettes as odorant applicators.
A screening test of olfaction was designed using 8 diskettes containing different odorants. The diskettes can be opened to release the odor and are closed after testing. The test was designed as a triple forced multiple choice test using a questionnaire, resulting in a score from 0 to 8 correct answers. Ninety-one volunteers with a normal sense of smell and 13 patients with subjective hyposmia or anosmia were tested to validate the developed test. The same volunteers were also tested with the sniffin' sticks test, another screening test of olfaction that is already validated. After testing, the volunteers were asked to compare the two tests.
Among the 91 volunteers with normal sense of smell, 10 achieved a score of 7, and 81 a score of 8 in the smell disk test. The 13 patients with hyposmia or anosmia achieved a score between 0 and 5. Based on the test design, there is a probability of 99.74% that a person who achieves a score of 7 or 8 will have normal olfaction. In the sniffin' sticks test, 85 volunteers with normal sense of smell achieved a score in the normal range for this test (6-8) whereas 6 volunteers were below with a score of 4 or 5. The 13 patients with hyposmia or anosmia scored between 0 and 6. The smell disk test was preferred by 86 persons, the sniffin' sticks test by 5, and 12 assessed both tests as equal.
The developed screening test is reliable for identifying patients with a normal sense of smell, and it can distinguish them from patients with hyposmia and anosmia. The diskettes proved to be reliable and comfortable applicators for odorants in clinical practice.
本研究的目的是开发一种新的嗅觉筛查测试，使用可重复使用的软盘作为气味施加器。
设计了一种嗅觉筛查测试，使用8个装有不同气味剂的软盘。软盘可以打开释放气味，测试后关闭。该测试设计为使用问卷的三联强迫多项选择题测试，正确答案得分为0至8分。对91名嗅觉正常的志愿者和13名主观嗅觉减退或嗅觉丧失的患者进行测试，以验证所开发的测试。同一批志愿者还接受了嗅棒测试，这是另一种已得到验证的嗅觉筛查测试。测试后，要求志愿者比较这两种测试。
在91名嗅觉正常的志愿者中，10人在气味软盘测试中得分为7分，81人得分为8分。13名嗅觉减退或嗅觉丧失的患者得分在0至5分之间。根据测试设计，得分7分或8分的人嗅觉正常的概率为99.74%。在嗅棒测试中，85名嗅觉正常的志愿者在该测试的正常范围内得分（6 - 8分），而6名志愿者得分低于正常范围，为4分或5分。13名嗅觉减退或嗅觉丧失的患者得分在0至6分之间。86人更喜欢气味软盘测试，5人更喜欢嗅棒测试，12人认为两种测试效果相同。
所开发的筛查测试对于识别嗅觉正常的患者是可靠的，并且可以将他们与嗅觉减退和嗅觉丧失的患者区分开来。在临床实践中，软盘被证明是可靠且舒适的气味施加器。
