Schematic diagram of the correctness verification using the example of C-reactive protein (CRP). The CRP test result was 1.8 mg/l and passed quality control. The autoverification system searched all the rules for the CRP and hit two of them, No. 001879 and No. 002009. The No. 001879 rule (verified) checks whether the CRP result has passed the quality control. The No. 002009 rule (pending verification) intercepts the results greater than or equal to 5. Therefore, when No. 002009 is triggered, the warning information of the sample appears purple, indicating that the technician needs to confirm whether the warning result is consistent with the manual judgment. In the correctness verification interface as shown in Fig. 3, the system provides two options, the human–machine judgment is consistent or the system judges incorrectly. The technician can confirm that the rule is performing correctly and change its status to “verified”
