Abstract: Objective：To analyze the research characteristics of domestic master and doctoral dissertations in the field of laboratory diagnosis research， reveal their publication status， research hotspots and frontiers， etc.， reflect the development trend in the field of laboratory diagnosis， and provide reference for relevant scholars to understand the development trend of the discipline. Methods： CNKI was used as the data source， and VOSviewer 1.6.15 and Excel 2019 were used to analyze and process the data， and generate the corresponding visual network knowledge map. Results:A total of 5228 relevant master′s dissertations were retrieved， and the institution with the most number of dissertations was Chongqing Medical University (289 dissertations). 568 relevant doctoral dissertations were retrieved， among which Peking Union Medical College (46 dissertations) was the institution with the most number of dissertations. The analysis of their research characteristics revealed that the main research content of master′s dissertations were related to clinical researches on various bacterial drug resistance， while doctoral dissertations were more inclined to the researches on drug resistance mechanisms of pathogenic bacteria. Laboratory medicine was the subject with the most number of master′s and doctoral dissertations. There was not much difference in the number of national-level funds and other level funds among master′s dissertations.The number of funds for master′s dissertations in laboratory medicine， analytical chemistry and internal medicine was much higher than that of other majors. The number of national-level funds for doctoral dissertations was much larger than that of other level funds and the funds were mainly concentrated in clinical laboratory medicine and biomedical engineering. Conclusion： The researches of master′s and doctoral dissertations in the field of laboratory diagnostics combines laboratory medicine with various medical specialties， biology， information technology， chemistry and other disciplines， breaking the barriers between traditional disciplines and realizing interdisciplinary integration.The overall research direction is gradually shifting from the macroscopic perspective to the microscopic perspective， and the breadth and depth of the research are expanding step by step.
