体检时抽多管血的原因/Reasons for drawing multiple tubes of blood during physical examination

为什么化验要抽多管血？很对人对此不理解，下面我们一起来看具体原因。

一、由于不同项目对血液检查的要求不一样，检验科无法用一管血完成所有的血液化验。

如血常规、凝血功能检查、血沉等需要用全血加不同的血凝剂检验，生化（肝功能、血糖、血脂等）需要分离血清，检查的项目不一样，对于血的要求肯定不一样的，所以，针对不同检验项目必须使用不同的试管装血液。

二、检验本身的需要

现在检验科分工越来越细，工作效率越来越高，为了保证检验质量，基本上都采用了一次性的负压管采血，以前医生用针筒给患者抽血后，再将血放入装有不同试剂的试管中，而现在是将血直接抽到封闭的试管里，这已经比以前减少了流程，提高了工作效率，而实际上抽出的血量是一样的。血液检验要求时间短，如果一管血在几个科室间传来传去，一方面容易产生污染，而且容易弄错。分管检验既科学，又节省时间。

Why do we need to draw multiple tubes of blood for laboratory tests? I don't understand this very well, let's take a look at the specific reasons together.

1、 Due to different requirements for blood tests in different projects, the laboratory cannot complete all blood tests with one tube of blood.

Blood tests such as routine blood tests, coagulation function tests, erythrocyte sedimentation rate tests, etc. require the use of whole blood with different coagulants. Biochemical tests (such as liver function, blood glucose, blood lipids, etc.) require the separation of serum, and the requirements for blood vary depending on the testing items. Therefore, different test tubes must be used to prepare blood for different testing items.

2、 The need to verify oneself

Nowadays, the division of labor in the laboratory is becoming more and more detailed, and the work efficiency is getting higher. In order to ensure the quality of the inspection, disposable negative pressure tubes are basically used for blood collection. In the past, doctors used syringes to draw blood from patients, and then put the blood into test tubes containing different reagents. Now, the blood is directly drawn into closed test tubes, which has reduced the process and improved work efficiency compared to before. In fact, the amount of blood drawn is the same. The blood test requires a short time, and if a tube of blood is passed between several departments, it is easy to cause contamination and make mistakes. The inspection in charge is both scientific and time-saving.
