Abstract: Methods, apparatus, systems and articles of manufacture to make and/or process diagnostic tests are disclosed. An example test device, such as a lateral flow immunoassay device, includes a conjugate pad including conjugates for a target analyte; and a test grid including a plurality of zones in a two-dimensional grid, the test grid including: a first test zone in the plurality of zones including at least one of first immobilized antibodies or first immobilized antigens to attach to the target analyte labeled with a first conjugate of the conjugates; and a second test zone in the plurality of zones including at least one of second immobilized antibodies or second immobilized antigens to attach to the target analyte labeled with a second conjugate of the conjugates.

Abstract: Methods, apparatus, systems, and articles of manufacture to make and/or process a diagnostic test device are disclosed. An example apparatus includes a sensor to measure a current between a first electrode and a second electrode of a bioelectrochemical cell coupled to a test zone corresponding to a target analyte on a porous media of a device; a processor to compare the current to a threshold; and when the current is more than the threshold, identify that the target analyte is present in a sample; and an antenna to wirelessly transmit results.

Abstract: The invention relates to a device for sample separation, particularly for blood separation, in which the sample liquid is introduced into a feed device. The sample flows vertically through a separating device such as a filter or a membrane, so that sample particles are retained and separated off. The sample liquid thus separated, particularly blood plasma, is received by an inlet chamber underneath the separating device and conveyed by means of a channel in the lateral direction out of the inlet chamber. Particularly advantageously, the channel extends into the inlet chamber, the channel being formed by a recess in the base of the inlet chamber.

Abstract: The invention relates to a microfluidic platform (1) having at least one means (12) for initiating a movement of a liquid (P), in particular a sample liquid, between at least two locations (100, 101) of the microfluidic platform (1). It is proposed according to the invention that the means (12) is embodied as an element of changeable volume and/or shape and is mounted on a cover-like component (11) that is movably connected to the microfluidic platform (1). By moving of the component (11) the element (12) can be brought into a position such that, by changing its volume and/or shape, it causes the liquid (P) situated at the location (100) to be moved at least partly from this location (100) to the other location (101). In this way a sample liquid (P) can be transferred from a sample application point (100) to a sample utilisation area (101) in a very simple and reliable manner.

Abstract: A method for filling a cavity, of a packaging, particularly a blister packaging, with a liquid and a packaging suitable for this purpose are proposed. The cavity is completely filled with the liquid by an acceleration force or by continuous throughflow.
