The invention discloses a blood code automatic matching method. The method comprises the following steps: before blood matching, performing searching in a blood matching instrument to check whether a same donor has more than two blood components needing cross blood matching at the same time in a stock or not; if so, prompting and displaying the blood components in a list form, and enabling a worker to select blood components for bar code conversion; if not, carrying out barcode conversion on only one blood component of the same donor; and after the experiment is completed, transmitting data to an LIS system, when blood component ISBT-128 standard codes are scanned, searching the converted 15-bit or 12-bit bar codes in a system code comparison table through the blood component codes, and after the corresponding bar codes are searched, acquiring and displaying blood matching results corresponding to the bar codes through the bar codes in a view mode. The method can effectively solve the problem that a blood matching instrument cannot recognize 23-bit bar codes of donors.
