The utility model relates to a transverse flow measurement object, a measurement object reader device and a system comprising the measurement object reader device. Aspects of the present disclosure relate to a lateral flow assay having a plurality of different detection zones that are adjusted to extend the dynamic range of the assay in a concentration indicative of harmful contaminants in a test sample. Some aspects relate to an assay reader device configured with instructions that generate a result indicative of a concentration of harmful contaminants in a test sample based on some or all of the detection zones. 本实用新型涉及横向流测定物、测定物读取器装置和包括其的系统。本公开的各方面涉及横向流测定物，该横向流测定物具有多个不同的检测区，该检测区被调整以在指示测试样本中有害污染物的浓度中扩展所述测定物的动态范围。一些方面涉及配置有指令的测定物读取器装置，所述指令基于所述检测区中的一些或所有检测区生成表示测试样本中有害污染物的浓度的结果。
