An embodiment of the invention relates to the technical field of sample detection and discloses a sample detection system. The sample detection system comprises a box, at least one sample detection device, a robot, a moving device and a controller and is characterized in that the box is provided with an accommodating space; the sample detection devices are arranged in the accommodating space; therobot is arranged in the accommodating space and used for performing sample detection; the moving device is arranged in the accommodating space, connected with the robot and used for driving the robotto move or rotate relative to the sample detection devices; the controller is connected with the moving device, the robot and the sample detection devices and used for controlling the moving device to drive the robot to move to one sample detection device, controlling the robot to perform sample detection and acquiring a detection result from the sample detection device. By the arrangement, the sample detection system is capable of effectively increasing sample detection efficiency and low in cost.
