    • Methods for quantitatively measuring the amount of an analyte of interest in a fluid sample are disclosed. The methods involve providing a membrane having an application point, a detection zone, and a contact region, where the contact region is between the application point and the detection zone, and has test particles and internal control particles imbedded within it; contacting the application point with the fluid sample; maintaining the membrane under conditions sufficient to allow fluid to transport analyte by capillary action to the contact region, where the analyte binds to the test particles; further maintaining the membrane under conditions sufficient to allow fluid to transport analyte-bound test particles and internal control particles to the detection zone, where they interact with a detection reagent; and detecting the amount of test particles and the amount of internal control particles in the detection zone. The amount of analyte in the fluid sample is related to a corrected test particle amount, which can be determined, for example, as the difference between the amount of test particles and the amount of internal control particles in the detection zone.
    • 公开了用于定量测量流体样品中目标分析物的量的方法。 所述方法包括提供具有施加点,检测区和接触区域的膜,其中所述接触区域在所述施加点和所述检测区域之间,并且具有嵌入其中的测试颗粒和内部控制颗粒; 使应用点与流体样品接触; 在足以允许流体通过毛细管作用将分析物输送到接触区域的条件下保持膜,其中分析物结合到测试颗粒; 进一步保持膜在足以允许流体将分析物结合的测试颗粒和内部控制颗粒输送到检测区域的条件下,其中它们与检测试剂相互作用; 并检测检测区域中的测试颗粒的量和内部控制颗粒的量。 流体样品中的分析物的量与校正的测试颗粒量相关,其可以例如作为检测区域中的测试颗粒的量与内部控制颗粒的量之间的差异来确定。
