    Aiming at developing a portable and speedy blood test device, a microfluidic system is designed and developed. Blood is injected into a hole with a diameter of 3.0 mm and a height of 3.0 mm. When the blood sample is transported from the bottom to the top of the hole, blood cells sediment at the bottom and plasma is separated at the upper side. Using this system, approximately 1 μL pure plasma can be obtained when blood is injected at a flow rate of 0.70 μL/min for 15 minutes. Moreover, by retaining the blood in the hole for seven minutes, pure plasma can be obtained 11 minutes later.
