Abstract: A method for analyzing a biological fluid specimen. The collection cartridge is inserted into a reader. The plurality of reactive elements of the collection cartridge following insertion of the collection cartridge is optically read recurrently. The first color change of at least one reactive element of the collection cartridge is detected and dated following the recurrent optical reading. The biological fluid specimen from the collection cartridge is analyzed following the detection of the color change of at least one reactive element of the collection cartridge.

Abstract: A device to collect a biological liquid sample to be inserted into a portable reader to analyze the biological liquid. The device includes a strip, an absorbent assembly, a band and a housing having a housing bottom. The color-changing reactive elements are arranged one after the other on an upper face of the strip. The absorbent assembly includes a deposition portion on which the biological liquid is deposited thereon. The band to diffuse the biological liquid arranged over the top of the reactive elements. The strip is arranged on the housing bottom with a lower face of the strip facing the housing bottom. Each reactive element is arranged by transparency through the strip facing an opening in the housing bottom. A cover is arranged over the top of the band and includes a protruding pattern forming a pressing surface configured to press the band into contact with the reactive elements.
