When you go to see a doctor after you are sick, many people will have this experience, that is, whether you go to an outpatient clinic or a hospital, the doctor will give yourself some blood sampling lists. As a result, one tube of blood follows another tube, not only when you are hospitalized A blood test is required, and a blood test will be performed on the day of discharge. Many people do not understand why the blood is always drawn when going to the hospital to see a doctor. Is this a necessary operation for doctors? What happens after the blood test is taken? For these questions, it is necessary for everyone to have a certain understanding of the following three common senses.
1. Why do we need to draw blood most of the time to see a doctor?
First of all, we need to know what role blood plays in our body. Some people say that blood helps transport nutrients and oxygen. This sentence is true. However, everyone may have a too narrow understanding of the role of blood. Blood is not only an important channel for transporting oxygen and nutrients, but also an important transport site for wastes, hormones, and metabolites after the metabolism of various organs in the body. There are many components in blood, which are actually secreted by cells or various tissues. Therefore, abnormal conditions in blood can indirectly reflect the health of organs or tissues.
2. Which diseases, the doctor will choose to take a blood test
For internal medicine diseases, the doctor can not know at a glance, only through basic inspections, and then combine some auxiliary examinations , To help oneself realize the accurate judgment of the disease, so at this time, blood drawing has become an effective combination method. The doctor will guess the possible disease site according to whether certain indicators in the blood are normal or not, and then Investigate one by one to help better understand the patient's condition, so that the patient can be accurately treated. Of course, some surgical diseases are not ruled out, especially for patients who need surgery. Doctors usually prescribe blood tests to understand the patient's liver and kidney function.
3. Where did the blood drawn finally go?
If you take a few tubes of blood every time you go to the doctor, some people will worry that they will lose too much blood and affect their health. In fact, the blood sample needed for a blood test will not affect the overall blood volume of the body at all, so there is no need to worry about anemia. In addition, since the blood is a biological sample, every time the doctor completes the examination, it will be sent to a place where the biological sample is specially processed, and the discarded blood will be uniformly processed and destroyed, so there is no need to worry about it.
