From the above research, it can be seen that different people have a good understanding about manual and operating well, and there is no ambiguity in the interpretation of test steps and test results. By using this reagent to test precision reference products in different laboratories, different test environments, and different testers, the test results are consistent and meet the test result requirements; the test results of the same model and the same batch of products on negative samples and different positive samples are consistent; the test results of the same model of three-batch products on negative samples and different positive samples are consistent. The above research shows that the product has good reproducibility in different locations, different operating environments, and different operators.
