A test element (110) for detecting at least one analyte in a body fluid is disclosed. The test element (110) comprises a housing (112) having at least one base element (114) and at least one cover element (116). The test element (110) further comprises at least one fluid channel (124) formed within the housing (112). The fluid channel (124) comprises a capil-lary region (126) and a measurement region (130), wherein the capillary region (126) and the measurement region (130) have differing aspect ratios. The cover element (116) com-prises at least one test field (138) having at least one test chemical (140). The test chemical (140) is adapted to change at least one optically measurable property in the presence of the analyte. The cover element (116) is mounted to the base element (114) by using at least one adhesive (134) which contacts the test field (138).本發明揭示偵測體液中之至少一種待分析物之測試元件(110)。該測試元件(110)包括具有至少一個基底元件(114)及至少一個覆蓋元件(116)之外殼(112)。該測試元件(110)進一步包括至少一個在該外殼(112)內形成之流體通道(124)。該流體通道(124)包括毛細管區域(126)及量測區域(130)，其中該毛細管區域(126)及該量測區域(130)具有不同的縱橫比。該覆蓋元件(116)包括至少一個具有至少一種測試化學品(140)之測試場(138)。該測試化學品(140)經調適以在該待分析物存在下改變至少一種光學可量測特性。藉由使用至少一種接觸該測試場(138)之黏著劑(134)將該覆蓋元件(116)安裝至該基底元件(114)。
