Abnormal blood lead levels in children detected in hospital, results were modified in violation of regulations.

The expert investigation team conducted an investigation into the blood lead test data issues at the Second People's Hospital of Tianshui City. They conducted on-site inspections of the relevant instruments and equipment in the testing department, interviewed relevant personnel, compared the relevant original data with the laboratory information system data, and reviewed the on-duty records of the testing personnel and the testing report records of the hospital. The investigation found that from May 1, 2024, to June 30, 2025, a total of 7 children from the Heshi Peixin Kindergarten had abnormal blood lead test results at the hospital, with levels of 176.65g/L, 161.68g/L, 292.37g/L, 153.39g/L, 251.08g/L, 440.14g/L, and 284.90g/L. Among them, the blood lead test results of 5 individuals were not modified, while the results of 2 individuals were modified from 292.37g/L to 42.37g/L and from 440.14g/L to 103g/L. For the same child who initially showed abnormal blood lead levels in November 2024 and experienced 5 more instances of abnormal levels within the following half a year, there was no alertness. For the same kindergarten, 7 children successively showed abnormal blood lead levels, but no systematic or correlated analysis was conducted, no warning was given to the kindergarten, and there was a lack of awareness of public health safety. The investigation concluded that the Second People's Hospital of Tianshui City and its testing department were in disorderly management, with inadequate implementation of job responsibilities, insufficient execution of laboratory quality control, a lack of systematic training for relevant testing personnel, and serious violations of professional ethics. It was deemed to be a serious breach of regulations such as the "Regulations on the Implementation of the Medical Institutions Management Regulations," "Clinical Laboratory Management Measures for Medical Institutions," "Technical Specifications for Blood Lead Clinical Tests," and "Code of Conduct for Medical Institution Practitioners." The investigation also revealed that there were previous instances of irregular modifications of blood lead test data in the testing department, and the disciplinary and supervisory authorities are conducting further investigations.
