PURPOSE: A lab-on-a-chip comprising a first reaction agent in a recessed region is provided to increase probability of reacting a fluid sample and the first reaction agent, and to improve diagnosis efficiency. CONSTITUTION: A lab-on-a-chip comprises an inlet(120o), a fluid channel, a first reaction part(A), and one or more second reaction parts(170,180,190). The inlet is used for injecting a fluid sample. The fluid channel is used for transferring the fluid sample. The first reaction part has a first reaction agent which reacts with a sample of the fluid sample and forms a first sample-reaction agent reactant. The second reaction part contains a second reaction agent which reacts with the first sample-reaction agent reactant and forms a second sample-reaction agent reactant, and is formed on the surface of the fluid channel.
