A diagnostic system for determining the presence of a target in a sample liquid that includes a diagnostic reader and a microfluidic strip having a microfluidic channel network therein. An actuator within the reader modifies the pressure of a gas in gaseous communication with a liquid-gas interface of a sample liquid within the microfluidic channel network to move and/or mix the sample liquid. The pressure modifications may be continuous and/or oscillatory.
