PURPOSE OF REVIEW
To review current indoor allergen sampling devices, including devices to measure allergen in reservoir and airborne dust, and personal sampling devices, with attention to sampling rationale and major indoor allergen size and characteristics.
RECENT FINDINGS
While reservoir dust vacuuming samples and airborne dust volumetric air sampling remain popular techniques, recent literature describes sampling using furnace filters and ion-charging devices, both which help to eliminate the need for trained staff; however, variable correlation with reservoir dust and volumetric air sampling has been described. Personal sampling devices include intra-nasal samples and personal volumetric air samples. While these devices may offer better estimates of breathable allergens, they are worn for short periods of time and can be cumbersome. Reservoir dust sampling is inexpensive and is possible for families to perform. Airborne dust sampling can be more expensive and may better quantify cat, dog, and mouse allergen exposure. Personal sampling devices may offer a better representation of breathable air.
目的综述
回顾当前室内过敏原采样设备，包括用于测量储尘和空气传播尘中过敏原的设备，以及个人采样设备，并注意采样原理和主要室内过敏原的大小和特征。
最新发现
尽管储尘真空吸尘采样和空气传播尘体积采样仍是流行的技术，但最近的文献描述了使用熔炉过滤器和离子充电设备进行采样，这两种方法都有助于减少对训练有素的工作人员的需求；然而，已经描述了与储尘和体积空气采样的可变相关性。个人采样设备包括鼻内样本和个人体积空气样本。虽然这些设备可以更好地估计可吸入过敏原，但它们佩戴时间短，而且可能很麻烦。储尘采样成本低廉，且家庭可以自行进行。空气传播尘采样可能更昂贵，并且可以更好地量化猫、狗和老鼠过敏原的暴露情况。个人采样设备可能更能代表可吸入空气。
