[Discussion of indoor quality control method of MPAIA antibody test of Schistosoma japonicum].
OBJECTIVE
To explore the scientific and effective indoor quality control method to ensure the results of Magnetic Particle Antibody Immunoassay (MPAIA) antibody test of Schistosoma japonicum reliable.


METHODS
The MPAIA antibody test indoor quality control work was performed with the combination of the crubbs method, Z-scores figure and Westgard multi-rules quality control method.


RESULTS
The crubbs test entered the quality control condition state from the third times, after 20 times, the test switched to Z-scores conventional quality control, and the Westgard multi-rules quality control method could help analyze the type of errors. From the third to fortieth test, 186 samples were completed and the tests of 9 samples among 2 batches needed to be re-done because of the failure of quality control. The test results of other 177 samples were acceptable.


CONCLUSIONS
The combination of the crubbs method, Z-scores figure and Westgard multi-rules quality control method can effectively accomplish the indoor quality control of MPAIA antibody test of Schistosoma japonicum.
