Abstract: A method for background detection of a sample pipeline of a sample processor, a sample processor and a computer-readable medium are provided. The sample pipeline is configured to connect a sample probe for aspirating a sample out of a sample container to a flow cell. The method includes the following steps executed by a control device: supplying sheath liquid to the flow cell via the sample pipeline; and detecting the sheath liquid flowing through the flow cell to obtain background detection data. The method according to the present disclosure performs background detection on sample pipeline of the sample processor by using sheath liquid, omitting preparation of a specialized fluid for background detection, significantly reducing costs and avoiding introduction of impurities to increase the background when the specialized fluid is loaded into the sample processor. Therefore, the detection precision and accuracy of the sample processor can be improved.
