1. A microfluidic diagnostic chip, comprising:

  • a number of input microfluidic channels;

    a number of output microfluidic channels;

    a number of interposing microfluidic channels, each fluidly coupled at one end to at least one input microfluidic channel and at a second end to at least one output microfluidic channel;

    first and second microfluidic sensors within the number of interposing microfluidic channels;

    a blocking device comprising a plurality of pillars to prevent particles of an analyte within the fluid from being sensed by the second microfluidic sensor, wherein the first microfluidic sensor measures an impedance of the fluid with particles and the second microfluidic sensor measures an impedance of the fluid without the particles;

    a bore; and

    a thermal resistor pump concentric to the bore to pump fluid through the bore, wherein the thermal resistor pump moves fluid across the first and second microfluidic sensors,wherein the microfluidic diagnostic chip is to compare output from the first microfluidic sensor sensing a fluid comprising an analyte to output from the second microfluidic sensor sensing the fluid lacking the analyte.
