    • Methods for quantitatively measuring the amount of one or more analyte(s) of interest in a fluid sample, and kits useful in the methods, are disclosed. The methods involve providing a solid phase apparatus comprising a membrane having an application point, a sample capture zone, and a control capture zone, where the sample capture zone and the control capture zone are approximately equidistant from the application point; and providing a sample collection apparatus comprising one or more population(s) of analyte binding particles. In the assays, a fluid sample is introduced into the sample collection apparatus, and the resultant mixture is applied to the application point of the membrane. The fluid allows transport components of the assay by capillary action to and through the sample capture zone(s) and the control capture zone. The amount of each analyte of interest in the fluid sample is related (e.g., either directly or inversely) to a corrected particle amount, which can be determined, for example, as a ratio of the amount of particles in the corresponding sample capture zone and the amount of particles in the control capture zone.

    • Methods for quantitatively measuring the amount of an analyte of interest in a fluid sample, and kits useful in the methods, are disclosed. The methods involve providing a solid phase apparatus comprising a membrane having an application point, a sample capture zone, and a control capture zone, where the sample capture region is between the contact region and the control capture zone; and providing a sample collection apparatus comprising a population of analyte binding particles or a population of analyte coated particles. In the assays, a fluid sample is introduced into the sample collection apparatus, and the resultant mixture is applied to the application point of the membrane. The fluid allows transport components of the assay by capillary action to and through the sample capture zone and subsequently to and through the control capture zone. The amount of analyte in the fluid sample is related (e.g., either directly or inversely) to a corrected particle amount, which can be determined, for example, as a ratio of the amount of particles in the sample capture zone and the amount of particles in the control capture zone.
    • 用于定量测量流体样品中感兴趣分析物的量的方法以及在所述方法中有用的试剂盒被公开。 该方法包括提供包含膜的固相装置,所述膜具有施用点,样品捕获区和对照捕获区,其中样品捕获区在接触区和对照捕获区之间; 并提供包含分析物结合颗粒群或分析物涂覆颗粒群的样品收集装置。 在测定中,将流体样品引入到样品收集装置中,并将所得混合物施加到膜的施加点。 流体通过毛细管作用允许测定的转运组分通过和通过样品捕获区并且随后通过和通过对照捕获区。 流体样品中的分析物的量与校正的颗粒量相关(例如,直接或相反),其可以例如确定为样品捕获区中颗粒的量与颗粒的量之比 在控制捕获区域。
