Automated pretreatment method for nucleic acid detection

The automatic pretreatment method comprises the following steps: a user selects a sampling tube type and a specimen type on a user interface; the system automatically sets a sampling and detecting pipe disc layout according to the type of the selected sampling and detecting pipe; the user selects at least one detection formula for each sampling and detecting tube; the system automatically lists an extraction agreement list for the user to select according to the selected specimen type; the system automatically displays detection disc configuration and reagent disc configuration on a user interface according to the sampling and detection tube disc layout and the selected detection formula, and guides a user to place a reagent; the system performs an extraction task according to the selected extraction protocol; the system is used for mixing reagents according to the selected detection formula and the configuration of the detection disc and sub-packaging the reagents into corresponding detection holes of the de
