A cartridge reader is configured to carry out a diagnostic test on a fluid sample contained within a fluidic cartridge (112, fig 5). The cartridge comprises first, second and third collapsible blisters (130a-c, fig 5) containing at least one reagent. The cartridge reader comprises an upper clamp 260, occupying a fixed position relative to the reader and a lower clamp (288, fig 21b), movable relative to the upper clamp, and where the upper clamp and the lower clamp are configured to receive and hold a fluidic cartridge therebetween. First, second and third blister actuators 278a-c are mounted on the upper clamp, for aligning with respective collapsible blisters of a fluidic cartridge inserted into the reader. The first, second and third blister actuators are movable relative to the upper clamp, between a first position in which the blister actuators are spaced apart from the collapsible blisters, and a second position in which the blister actuators depress and collapse the blisters, ejecting the reagents contained within them into a channel of the fluidic cartridge. The fluidic cartridge may be used for performing PCR. |
