Device and method for testing biological samples

A device for testing a biological sample, comprising:

• a first reaction chamber and a second reaction chamber, each reaction chamber having an interior wall defining an open top and a cavity for receiving a reaction mixture;
• a housing positioned below the first reaction chamber and the second reaction chamber, the housing having a top portion, a bottom portion, a back wall, and two opposing side walls defining an open end and an insertion area for receiving a test cassette;
• and
• a pair of doors positioned in the top portion of the housing, each door including a ramp downwardly extending into the insertion area such that biasing the ramp upwards opens the door into the cavity of each reaction chamber and places each reaction chamber in fluid communication with the insertion area.

A method for testing a biological sample for an analyte of interest, comprising:

• providing a device, including:
• a reaction chamber having an interior wall defining an open top and a cavity for receiving a reaction mixture;
• a housing positioned below the reaction chamber, the housing having a top portion, a bottom portion, a back wall, and two opposing side walls defining an open end and an insertion area for receiving a test cassette;
• and
• a door positioned in the top portion of the housing and including a ramp downwardly extending into the insertion area such that biasing the ramp upwards opens the door into the cavity of the reaction chamber and places the reaction chamber in fluid communication with the insertion area;
• placing the biological sample and one or more reagents into the cavity to thereby create the reaction mixture;
• inserting an immunoassay test cassette into the insertion area such that the test cassette biases the ramp upwards and opens the door into the cavity of the reaction chamber to allow the reaction mixture to contact an immunoassay test strip;
• and
• determining an amount in the biological sample of the analyte of interest.
