A test carrier for the analytical determination of a component of a liquid sample, especially for the diagnosis of diseases, in which a reaction sequence taking place on a test carrier having a base layer, a liquid transport path which extends from a sample application region to an evaluation region and a signal formation layer in which, on the basis of a signal formation reaction, with the help of a signal formation reagent system, an optically determinable change characteristic for the component to be determined takes place. At least one signal formation reagent is present in the signal formation layer. In the evaluation region, there is provided a liquid transport layer which is an absorbent material which is in fluid contact with the liquid transport path. The signal formation layer runs parallel to the liquid transport layer, the signal formation layer is in liquid contact via a liquid exchange surface with the liquid transport layer perpendicularly to the plane of the base layer and the speed of liquid transport of the liquid transport layer and the chronological commencement of the signal formation reaction in the signal forming layer are adapted to one another in such a manner that the liquid first spreads out in the liquid transport layer and the signal formation reaction takes place substantially thereafter.

Test carrier for the analytical determination of a component of a liquid

The present invention provides a test kit and a process thereof for the determination of an analyte in a pasty sample, especially in faeces, containing a sample application region which has a sample layer with a sample field for the application of a sample. An analysis device with reagents is provided which reacts with the analyte and includes a component producing a detection signal. The sample layer includes a material which is capillary-active so that a liquid is transported therein by capillary action.

Test kit and process for the determination of an analyte in a pasty

The present invention provides erythrocyte-retention substrates of the general formula:

Erythrocyte-retention substrates

A test strip has a reagent-containing film layer coatingly embedded at least preponderantly on and into only one side of a carrier layer made of a multifilar fabric or fleece.

Test strips and a process for the production thereof

A test strip has a reagent-containing film layer coating embedded at least preponderantly on and into only one side of a carrier layer made of a multifilar fabric or fleece.
