Abstract: Objective To understand the ability of the CDC to detect ammonia nitrogen in drinking water in Hubei Province. Methods The blind samples of two concentration levels were tested in the laboratories of the disease control institutions in the province, and the test results were evaluated by double-sample Z score. Results The satisfaction rate was 76.29% (74/97), the problem rate was 15.46% (15/97), and the dissatisfaction rate was 8.25% (8/97). Conclusion The detection ability of ammonia nitrogen in drinking water in laboratories of disease control institutions in Hubei Province is generally high，however，some laboratories need to be further improved.
