A fluid control apparatus for controlling a fluid in a microfluidic device. The fluid control apparatus includes a detecting unit including a light source for irradiating light toward the microfluidic device, and a photodetector for detecting light reflected from the microfluidic device, a transporting unit for moving the detecting unit; and a determining unit for controlling a transporting operation by the transporting unit, where determining a state of a fluid at a particular position relative to the microfluidic device is based on light reflected from the microfluidic device.
