实验室生物安全的重要性逐渐被人们认识，但仍有一些生物安全问题被医学实验室忽视，如常规标本和细胞培养系中可能存在病原，用于检测样本的实验室设备可能被病原污染。对这些被忽视的生物安全问题，应在具体工作中加以关注，并提高必要的个人防护水平。

People are gradually aware of the importance of laboratory biosafety, but some problems of biosafety in medical laboratories are often neglected, such as pathogens in samples, pathogens in culture cells and the contamination of laboratory instruments. These risks should be paid more attention to enhance the personal protection equipments during specific work.
