A system and method for processing fluid in a fluidic cartridge is provided. The system comprises a fluid pathway for passing a liquid sample therethrough from an upstream end to a downstream end, a sample processing chamber (C102) with in the fluid pathway having an in let valve (C101) upstream of the sample processing chamber (C102), a downstream sample processing reg ion (C104) with in the fluid pathway downstream of the outlet valve (C103) and a bypass channel (C105) coupled to the fluid pathway at a junction between the outlet valve (C103) and the downstream sample processing region (C104), the valve system configured such that surplus liquid downstream of the outlet valve (C103) may be evacuated through the bypass channel (C105) when the outlet valve (C103) is closed, thereby leaving a metered volume of liquid sample between the in let valve (C101) and the downstream sample processing region (C104). |
