An automatic in-vitro diagnosis method for automatically performing a diagnosis by analyzing a specimen taken from a human body, the method comprising: providing a storage body to a housing, the storage body containing the specimen, a reagent to be mixed with specimen, an analysis strip, and a suction tip, and manipulating diagnosis operation on a manipulating a display unit connected to a controller by a user; mounting the suction tip of the storage body to a suction unit for applying suction pressure, the storage body being moved to a transfer unit according to a control signal of the controller upon the manipulation, moving the mounted suction tip to a position of the specimen, and sucking the specimen with the suction tip; moving the suction tip which suck the specimen to a position of the reagent, and mixing the specimen with the reagent through successive suction and discharge; dropping the mixture solution of the specimen and the reagent onto the analysis strip contained in the storage body, and removing the suction tip to the outside by allowing the suction tip to be caught in the transfer unit, while moving up and down the suction tip after the dropping wherein, after the suction tip finished dropping the mixture solution, the suction tip moves up and the transfer unit moves to the other side, subsequently the suction tip moves down to a position at which it will be caught in an end of the transfer unit, and the transfer unit moves to a side at which the suction tip will be caught, then the suction tip moves up and is caught in the transfer unit, thus, the suction tip is removed down; moving the analysis strip on which the mixture solution dropped to an analytic diagnosis unit for optically making an analytic diagnosis, and diagnosing; and discharging the storage body to the outside by operating the transfer unit, after the diagnosis. providing a storage body to a housing, the storage body containing the specimen, a reagent to be mixed with specimen, an analysis strip, and a suction tip, and manipulating diagnosis operation on a manipulating a display unit connected to a controller by a user; mounting the suction tip of the storage body to a suction unit for applying suction pressure, the storage body being moved to a transfer unit according to a control signal of the controller upon the manipulation, moving the mounted suction tip to a position of the specimen, and sucking the specimen with the suction tip; moving the suction tip which suck the specimen to a position of the reagent, and mixing the specimen with the reagent through successive suction and discharge; dropping the mixture solution of the specimen and the reagent onto the analysis strip contained in the storage body, and removing the suction tip to the outside by allowing the suction tip to be caught in the transfer unit, while moving up and down the suction tip after the dropping wherein, after the suction tip finished dropping the mixture solution, the suction tip moves up and the transfer unit moves to the other side, subsequently the suction tip moves down to a position at which it will be caught in an end of the transfer unit, and the transfer unit moves to a side at which the suction tip will be caught, then the suction tip moves up and is caught in the transfer unit, thus, the suction tip is removed down; moving the analysis strip on which the mixture solution dropped to an analytic diagnosis unit for optically making an analytic diagnosis, and diagnosing; and discharging the storage body to the outside by operating the transfer unit, after the diagnosis.
