新型冠状病毒（SARS-CoV-2）席卷全球，给人民的生命安全带来了巨大威胁。高效而精准的开展核酸检测工作，为疫情防控的胜利贡献了自己的力量。然而核酸检测工作中也暴露出了一些问题如生物安全防护不完善、检验人员身心压力过大和分子生物学知识不足等。医学检验专业学生是核酸检测的后备军，暴露的这些问题给了研究者反思医学检验专业教学的机会。医学检验专业教学内容中尚缺乏生物安全教育、心理教育、思政教育、临床思维教育以及深入的分子生物学教育内容。在新冠疫情背景下，研究者从实践到教学的环节中反思核酸检测中暴露的问题，通过改变传统教学思维、增加实践教学、组织教学活动等方式来尝试弥补医学检验专业教学的漏洞和解决一线核酸检测中暴露出来的问题。

SARS-CoV-2 sweeps the world, posing a great threat to people's lives. As a scout on the battlefield of fighting against the COVID-19, clinical laboratory technician has overcome various difficulties, carried out nucleic acid detection efficiently and accurately, and contributed to the victory of COVID-19 prevention and control. However, some problems have also been exposed in nucleic acid detection, such as imperfect biosafety protection, excessive physical and mental pressure of clinical laboratory technician and insufficient knowledge of molecular biology. Medical laboratory students are the reserve force for nucleic acid testing. These problems give us the opportunity to reflect on the teaching of medical laboratory specialty. The teaching contents of medical laboratory specialty lack of biological safety, psychological, ideological and political, clinical thinking and in-depth molecular biology education. Under the background of COVID-19, researders reflected on the problems exposed in nucleic acid testing from practice to teaching, try to make up for the loopholes in the teaching of medical laboratory specialty and solve the problems exposed in the first-line nucleic acid testing by changing the traditional teaching thinking, increasing practical teaching and organizing teaching activities.
