Claim 16:
17. A fluid detection method comprising the following steps:
providing a microfluidic detection unit which comprises a detection section, at least one fluid injection section, a fluid storage section and at least one input channel;
injecting a first fluid from the at least one fluid injection section, such that the first fluid is driven by gravity to pass through the at least one input channel to enter the detection section and is stopped between the fluid outlet of the fluid injection section and the fluid storage section to accumulate to form a droplet at the fluid inlet of the fluid storage section, and a height along the direction of gravity of the droplet is between a bottom surface of the substrate and the fluid outlet of the fluid injection section, such that a gravitational potential and a capillary force opposite to a direction of gravity of a portion of the first fluid in the at least one input channel and between a fluid outlet of the at least one fluid injection section and a position with the height along the direction of gravity of the droplet are offset to establish a state of fluid pressure equilibrium; and
detecting the first fluid in the detection section.
