A multizone element and method are designed for use for the determination of an analyte in whole blood. In particular, this element and method is useful for the quantitative determination of peroxide-generating analytes, such as glucose or cholesterol, in whole blood. The multizone element has a support having thereon, in order and in fluid contact, a registration zone and a reagent/spreading zone but excludes a whole blood cell filter zone. The reagent/spreading zone has a void volume and average pore size effective to accomodate whole blood, and contains an interactive composition necessary for the analysis. Such composition is capable of providing, upon interaction with the analyte, a dye which can be spectrophotometrically detected at a wavelength greater than or equal to 600 nm.
一种多区元件和方法设计用于测定全血中的被分析物。 特别是,这种元件和方法可用于定量测定全血中产生过氧化物的被分析物,如
葡萄糖或
胆固醇。 多区元件有一个支撑物,其上依次有一个登记区和一个试剂/扩散区,但不包括一个全血细胞过滤区。 试剂/扩散区的空隙体积和平均孔径可有效容纳全血,并含有分析所需的交互组合物。 这种组合物在与被分析物交互作用时能够提供一种
染料,该
染料可在大于或等于 600 纳米的波长下进行分光光度检测。
