More Information
Summary:A lateral flow test system having an optical reader (11), a lateral flow cartridge (17) and a computer system (13) is provided. The lateral flow cartridge includes a porous test strip with a reading window into the porous test strip exposing an exposed zone of the porous strip. The optical reader has a reader housing (11a) and a slot for inserting the cartridge into the reader housing. The optical reader has an illumination arrangement (15) adapted for illuminating the exposed zone of the porous strip when the cartridge is inserted into the slot. The optical reader further has a video camera (14) configured for acquiring a series of digital images comprising the exposed zone of the porous strip. The computer system receives sets of pixel data representing the plurality of consecutive digital images and calculates wetting progress along the length of the exposed zone of the porous strip based on the sets of pixels data.
