    • The invention concerns a diagnostic test carrier (1) containing a supporting layer (2) with a detection layer (3) arranged thereon containing the reagents required to determine an analyte in a liquid sample and a network (4) covering the detection layer (3) which is larger than the detection layer (3) and which is attached to the supporting layer (2), wherein the network (4) is a plied knitted fabric the threads of which are highly roughened on the side facing the detection layer (3) whereas the threads on the side of the knitted fabric which face away from the detection layer (3) are relatively smooth as well as the use of such a test carrier to determine an analyte in a liquid and the use of such a knitted fabric as a layer spreading liquid in a diagnostic test carrier. Moreover the invention concerns a method for the determination of an analyte in a liquid sample with the aid of a test carrier according to the invention.

    • The invention concerns a diagnostic test carrier (1) containing a supporting layer (2) with a detection layer (3) arranged thereon containing reagents required for the determination of an analyte in a liquid sample and an inert layer (4) covering the detection layer (3) wherein the inert layer (4) is arranged at such a distance (5) from the detection layer to enable a capillary active liquid transport between the detection layer and inert layer (3,4), characterized in that the inert layer (4) extends beyond the detection layer and wherein the area (10) that extends beyond the detection layer is attached to the supporting layer (2) in such a way that a continuous capillary active liquid transport between the inert layer and detection layer (4,3) and between the inert layer and supporting layer (4,2) is possible and in addition the inert layer (4) contains several holes (7) in the area of the detection layer (3) through which the sample to be examined and the components contained therein can be applied to the detection layer (3) as well as its use for the determination of an analyte in a liquid.
    • 本发明涉及一种包含支撑层(2)的诊断测试载体(1),其上布置有检测层(3),其上包含测定液体样品中的分析物所需的试剂和覆盖检测层的惰性层(4) (3),其中所述惰性层(4)与所述检测层距离所述距离(5)设置,使得能够在所述检测层与惰性层(3,4)之间进行毛细管活性液体输送,其特征在于,所述惰性层( 4)延伸超过检测层,并且其中延伸超过检测层的区域(10)以使得在惰性层和检测层(4,4)之间的连续毛细管活性液体传输的方式附接到支撑层(2) 3),并且在惰性层和支撑层(4,2)之间,并且另外,惰性层(4)在检测层(3)的区域中包含几个孔(7),待检样品通过该孔 其中所含的组分 可以应用于检测层(3)以及其用于测定液体中的分析物的用途。
