Lamp component distribution in a microfluid cell

A microfluidic test device comprising:

• a body;
• a first chamber having an outlet provided with a first valve and configured to hold a first buffer having a first buffer volume;
• a primary reaction chamber;
• a sample inlet for receiving a sample and being configured for feeding a sample having a sample volume, into the device;
• a first fluid path in fluid communication with the outlet of the first chamber and the sample inlet;
• a second fluid path in fluid communication with the sample inlet and the primary reaction chamber;
• a primary test part comprising a primary test chamber;
• a third primary fluid path in fluid communication with the primary reaction chamber and the primary test part;
• a primary valve arranged in the third primary fluid path;
• and
• a flow driving device configured to move fluid from the primary reaction chamber to the primary test part, wherein first buffer is configured to flush sample in the sample inlet through the second fluid path and into the primary reaction chamber, where the first buffer, the sample and a primary reaction material are mixed;
• and
• wherein the microfluidic test device comprises the primary reaction material in a lyophilized form, and wherein the primary reaction material and the first buffer are arranged on different, opposing sides of the sample inlet.
