1-32. (canceled)
A microfluidic device for analyzing a liquid sample, comprising:
- a first microfluidic channel having a first end and a second end;
- a sample inlet fluidly connected to the first end of the first microfluidic channel for receiving the liquid sample;
- a bellows pump fluidly connected to the second end of the first microfluidic channel;
- a second microfluidic channel having a first end, fluidly connected to the sample inlet, and a second end, fluidly connected to the bellows pump;
- and
- a third microfluidic channel having a first end, fluidly connected to the sample inlet, and a second end, fluidly connected to the bellows pump,
- wherein the first microfluidic channel comprises a first dried reagent zone wherein a first reagent is printed, the second microfluidic channel comprises a second dried reagent zone wherein a second reagent is printed, and the third microfluidic channel comprises a third dried reagent zone wherein a third reagent is printed.
