Problems solved by technology

The need and ability to move immunoassay IVDs toward capillary finger-stick blood testing has been hampered by technology development, yet it still remains due to the reduced complexity it allows and a larger product position in current or untapped markets. A golden target for many diagnostic companies

Embodiment Construction

[0084] exist figure 1 A sample assay cartridge ( 10 ) according to an embodiment of the invention is shown in . A fluid such as blood (eg via a finger or venous blood) is applied to the sample input port (12). In this particular embodiment, two channels (14, 16) spanning from one of said sample input ports (12), the two channels (14, 16) are separated and not connected, although for the user applying blood Say the channel may only appear as one. Although not to be construed as limiting the invention, further description will relate to samples which are whole blood samples.

[0085]Depending on the number of channels filled, the total sample application can be less than 1 μl, so when the user applies a sample (eg a drop of blood), both channels (14, 16) will be filled under capillary force. This process is very fast and is more suitable for blood glucose strip filling as opposed to the tedious separate blood filling of some immunoassay benches. Stored in the two channels (1...

Description

technical field [0001] The present invention relates to a microfluidic analytical system comprising a single-use analytical cartridge and an associated reader device as well as the individual components themselves. The invention also relates to methods of performing assays using the assay cartridges and devices of the invention and kits for performing assays. Background technique [0002] The in vitro diagnostic (IVD) market is highly competitive and there is a constant need to develop fast, small volume, accurate and inexpensive IVD tests in the IVD market. This is coupled with the reality that there is a strong market need to develop a capillary finger stick blood test that reduces patient complexity to allow full market penetration (eg, in nursing, physician surgery, home, etc.). This capillary fingerstick IVD testing format has proven very successful for diabetes testing, growing to a $3.5 billion market (ref: Medical Devices Today). The need and ability to move immuno...
