Abstract:
Objective:To analyze the results of external quality assessment (EQA) of Shanghai Nuclear Medicine Quality Control Center, in order to further strengthen the quality control and management of in vitro testing laboratories. Methods:The EQA results of 41 units evaluated by Shanghai Nuclear Medicine Quality Control Center from 2004 to 2018 were summarized and retrospectively analyzed. The overall qualified rate of all items (total triiodothyronine, TT 3; total thyroxine, TT 4; free triiodothyronine, FT 3; free thyroxine, FT 4; thyroid stimulating hormone, TSH; alpha fetoprotein, AFP; carcinoembryonic antigen, CEA; total prostate specific antigen, TPSA) and the qualified rate of singe item over the years were calculated respectively. Results:From 2004 to 2018, the overall qualified rates of all items of the laboratories were 84.0%(356/424), 90.1%(381/423), 94.8%(399/421), 94.8%(291/307), 96.6%(308/319), 97.2%(280/288), 96.6%(224/232), 97.8%(225/230), 98.7%(224/227), 100.0%(221/221), 99.5%(218/219), 98.6%(215/218), 99.5%(217/218), 99.5%(189/190), 100.0%(90/90), respectively; and the qualified rate of singe item showed an upward trend, but there were still some laboratories′ EAQ results did not reach " qualified" , and there may be potential risk factors affecting the test results during the test process.Conclusions:The qualified rates of in vitro testing laboratories evaluated by Shanghai Nuclear Medicine Quality Control Center show an upward trend from 2004 to 2018. Analyzing the EQA results can help to find the potential risks in the laboratory and improve the detection ability.
