Resident A: "The hospital now is really crazy to make money!"
Resident B: "What do you say?"
Resident A: "I felt a little uncomfortable some time ago. I went to the hospital for a check-up. The doctor gave me a lot of check-ups. I ran for a whole morning but didn't get through. What else do you have to do with blood regular . The doctor immediately drew blood from three big tubes. The nurse didn't blink. Isn't he? She doesn't feel sorry for her blood."
Resident B: "You said this, it's true. I remember that I hadn't recovered from the cold before. When I went to the hospital for examination, the doctor asked me to draw blood. It really took a lot of it."
Many people have a question in their minds, that is, why go to the hospital for treatment, the doctor can clearly know what disease he has. Even if it is a serious illness, it's all right. Even if it's a minor illness, it's going to draw blood, which makes the patient trouble.
Because everyone didn't know what the purpose of blood draw was, the doctor just glanced at it, but he didn't understand it. He felt that his blood from several large tubes wasted. Did the hospital deliberately ask the doctor to arrange it? Blood draw is really useless? Where did the blood draw end? Today I will tell you a good article.
Why do you need to draw blood for major and minor diseases? How many tubes are drawn at a time?
first tell you first, this is normal, don’t think too much, even doctors, you will not go to the hospital in the future to save money?
The reason why
draws blood because blood is spread throughout the body, which can reflect some physical problems, such as organ function, identification of causes of the disease , etc.
Blood routine, liver and kidney function, blood sugar, blood lipids , etc. These items require blood draw. helps doctors to further diagnose your condition. Many related information about diseases can be discovered through blood tests.
For example, if your skin is itchy, the patient will think it is a skin disease, or because the weather is too dry. But in the eyes of doctors, it may be high blood sugar , so blood sampling and testing blood sugar is necessary. It may also be uremia , so you need to draw blood to check whether the blood creatinine index is normal, and it may also be cirrhosis , so do you also need to draw blood to check some liver function ?
So, if the doctor asks you to draw blood or be responsible for you, you should still thank the doctor.
As for why one draw is "several tubes", there is a reason
Because there are many examination items. If you share the blood of a tube, Laboratory and are not only your blood. The environment is complex. can easily cause blood contamination of , which will also affect the results of the examination. If you pump several tubes, it saves time for the test and can also prevent bad effects.
Many people always feel distressed when they see the red blood in their bodies being pulled away, thinking how much nutritious it needs to be eaten to make up for it? Will it cause anemia ?
Drawing several tubes of blood will cause anemia, and you underestimate the body's hematopoietic function
Normally, the blood in a person's body is about 4000-5000ml. If a person loses 800ml blood in a short period of time, the body will feel uncomfortable, and there are symptoms such as pale face, cold hands and feet, rapid breathing, and rapid pulse . If the blood loss of is 1500ml, the body will be in the state of severe ischemia . insufficient blood supply to the brain causes dizziness, blurred vision, thirst, and coma .
The country now advocates donating blood to hospitals, not only because it can save the lives of other patients, but also because appropriate donation of blood can also stimulate the body's hematopoietic industry, prevent blood viscosity, prevent cardiovascular and cerebrovascular diseases, etc.But the maximum blood donation at one time is about 400ml.
And the tube for congestion examination in the hospital is only 2-5ml per tube. Even if you draw 10 tubes, it will be only 50ml at most. Compared with blood donation, you can say that it will be a drop in the bucket. You don’t have to worry about it causing anemia in your body or other adverse effects on the body. If you really feel distressed, you can also eat some animal liver, egg yolks, soybean and chickpea products, fungus , mushrooms, and some foods rich in vitamin C after you go home.
The last question, where did the blood drawn go? It entered the blood bank?
After a little blood drawn from the blood test form, it will not enter the blood bank, because the blood drawn must be processed after complicated and stored. This will cost a lot of manpower and financial resources. , then a little blood is not worth it.
When your blood is drawn out, after the test is completed, will not throw away your blood immediately, but will keep . After the doctor has questions about your examination results, you can do another test.
If there is no objection and after a certain period of time, your blood will be considered Medical spam and is processed by a professional processor.
So, the doctor asks you to draw blood for your own good, not for making money. Doctors in regular hospitals will not do it, but Private hospital or small clinics may be.
Some small matters when drawing blood. You must know that
can appropriately drink water , but don’t drink too much, as it will affect the examination results. There is no need to deliberately eat any nutritious foods. Just eat a light diet at a little before going to the hospital, especially . Don’t eat high-fat foods, don’t drink alcohol, don’t stay up late, don’t exercise vigorously, etc.
Some items require blood draw on an empty stomach, preferably empty stomach . However, in people with hypoglycemia , it is best to ask the doctor to give you to arrange it as soon as possible, prevent hypoglycemia, carry with you, chocolate, candy , etc.
When drawing blood Don’t be nervous , as nervousness will cause blood vessels to contract, affect blood draw, and may ask you to draw again. After
blood is drawn, gently press the needle to prevent bruising. If the clothes are too tight, it will affect the bleeding. If you feel dizzy, lie down and rest for a while, and drink some water for . If your arms are swollen, apply it to a hot towel for a while.
In short, it is normal to go to the hospital if you are sick. The doctor will ask the blood to be drawn when you are sick. Just to help you make further diagnosis of your condition. Blood drawing will not cause anemia. Just do precautions for blood drawing.
