FIELD: chemistry.
SUBSTANCE: test device has two surface impermeable layers, a layer of absorbing matrix material on which the reagent is applied and which is placed between the impermeable layers. One of the impermeable layers has multiple openings superimposed with the matrix material and capable of absorbing the sample into the matrix material from the surface. The device is laminated and is fitted with apparatus for separating the sample from the surface when rubbed. Disclosed is an alternative version of the test device, versions of the method of extracting the sample from the surface of test devices and a method of making the test device. The invention increases adhesion strength between layers of the test devices and ensures separation of the sample from the surface of the devices when rubbed.
EFFECT: high-speed and large-scale manufacturing of test devices.
