Counting method of reaction cups, sample analyzer and computer readable storage medium

The invention provides a counting method of reaction cups, a sample analyzer and a computer readable storage medium, specifically, the counting method of the reaction cups is applied to the sample analyzer, the sample analyzer comprises a cup disc used for placing the reaction cups and a gripper used for gripping the reaction cups, the gripper is provided with an inductor, and the inductor is connected with the cup disc. The inductor is used for inducting whether reaction cups exist in the cup plate or not. The counting method comprises the steps that the available number of the reaction cups in the cup plate is obtained through the inductor on the gripper; when the sample analyzer performs item detection, on the basis of the available number of the reaction cups, the grippers are controlled to sequentially move to the corresponding positions of the cup disc to grab the reaction cups; and obtaining the residual quantity of the reaction cups according to the available quantity of the reaction cups and the quan
