The invention discloses an intelligent detection device for detecting procalcitonin. The intelligent detection device for detecting the procalcitonin comprises a slide, a reaction plate and a box body, wherein the reaction plate is arranged on the slide; the bottom surface of the lower part of reaction plate is attached to the upper surface of the slide; the reaction plate is a rubber plate; a serum storage groove and a group of reaction grooves are formed in the reaction plate; a serum adding passage communicating with the serum storage groove is arranged at one end of the reaction plate; an inlet of the serum adding passage is located on an end surface of one end of the reaction plate; the serum storage groove in the reaction plate communicates with each reaction groove through a passage; the reaction grooves in two sides of the passages are formed in a staggering manner; liquid sucking paper is arranged, on the outer side of each reaction groove, on the reaction plate; the passages are oblique; sides, approaching the serum storage groove, of the passages are higher than sides, approaching the reaction grooves , of the passages; procalcitonin antibody coating positioning grooves are formed in the reaction grooves; the reaction plate and the slide are arranged in the box body. The detection device can be used for procalcitonin antibodies with multiple concentrations to synchronously detect the procalcitonin respectively.
