Immunochromatographic test strip with multiple flow paths, and manufacturing method therefor

A test strip comprising:

• at least two spaced-apart flow paths of porous material on a common carrier,
• each of the at least two spaced-apart flow paths comprising a first end in contact with a feed material and a reagent reservoir adjacent to the flow paths,
• a detection area in each of the at least two spaced-apart flow paths between its first end the first and its-an opposite second end, and
• a control area in each of the at least two spaced-apart flow paths between the detection area and the second end, wherein the reagent reservoir is subdivided into compartments, each of which is individually connected to one of the at least two spaced-apart flow paths, wherein and each of the compartments or each of the at least two spaced-apart flow paths has comprises a controllable barrier arranged to allow the sample to flow into each of the at least two spaced-apart flow paths after opening.
