Background
A plurality of biological test tubes are arranged in a traditional biological sample box, so that biological sample processing personnel can conveniently move and carry out detection on biological samples in each biological sample test tube. In order to enable a biological sample handler to know the relevant information of each biological sample tube, a label may be attached to the outside of the biological sample tube, or a recording mode may be required to ensure the storage or use of each biological sample tube.
