After donating blood for the second time, the hospital didn’t notify me that my blood test passed?

The three types of blood cells contained in blood are: red blood cells, white blood cells, and platelets.

Each component of blood has its special function. Plasma can carry water, salts, nutrients, hormones and drugs to our tissues, and carry away metabolic waste to the lungs and kidneys. It is excreted from the body through breathing and urine. White blood cells can help your body fight infection. The main function of platelets is to stop bleeding. When you are injured, they will stick together and block the holes in the blood vessels to prevent further blood loss.

Red blood cells are the most numerous cells in the blood. They are filled with red hemoglobin, so the blood looks red. As we all know, survival is inseparable from oxygen. The oxygen inhaled by people in the lungs is combined with hemoglobin and transported to various tissues throughout the body to complete cell metabolism. The lifespan of red blood cells is only 120 days, and they are destroyed in the spleen. All blood cells are differentiated from hematopoietic stem cells in the bone marrow.

This can clearly see how important blood is to the body, so why is donating blood harmful to the body?

Because donating blood will cause the above blood functions to be weakened or even lost. To put it simply: the reduction of red blood cells will cause various organs in the body to not receive enough oxygen, and the various life functions of the cells cannot be performed. The dizziness caused after donating blood is because the brain does not receive enough oxygen supply, and when carbon monoxide poisoning occurs, The phenomenon is a truth.

The decrease in white blood cells will reduce the body's ability to resist viruses and make it easier to get sick. This is the reason why the body becomes weak after donating blood. The decrease in immunity will allow viruses such as colds to take advantage of them.

By the way, let me tell you that another name for the famous AIDS is "acquired immunodeficiency syndrome". The lack of platelets will make it difficult to heal wounds and cause bleeding. Of course, no one will be unlucky enough to donate blood. Injured after bleeding.

By the way, let me tell you that one of the most serious consequences of leukemia is thrombocytopenia (older people should have watched "Blood Doubt", right?)

Someone just said I said: I, what you said is wrong. Everyone says that after donating blood, the body will produce enough blood to replenish it. I just said that "all blood cells are differentiated from hematopoietic stem cells in the bone marrow." Hematopoietic stem cells have a long life span, which means that the hematopoietic function of hematopoietic stem cells is not unlimited.

There is a very simple example: the bone marrow hematopoietic function of most elderly people is only 50% of that of young people. Due to the decrease in hematopoietic function, anemia is prone to occur and is difficult to recover. So I think hematopoietic stem cells are consumables and cannot be recovered!

Someone else said: The book says that the blood volume will be replenished 2 weeks after donating blood. Yes, you are right, but please note: What is added? As far as I know, the body should replenish plasma within 2 weeks. Plasma and blood are two different concepts. The components of plasma include: water (91%), protein (7%), lipids (1%), sugars (0.1%), inorganic salts (0.9%), and metabolites. . . Did you see it? Here is a simple example: you will feel thirsty after donating blood because you need to replenish plasma. Blood stations will provide sugar water or milk for free. This is why you understand?

Some people say: I know everything you said, but for the happiness of the majority of patients, I will give it. OK! You are great and I admire you. However, when you don’t donate blood for free, will the patient have no blood to transfuse? Of course this is not the case. I may have been working in the hospital longer than you. I have to tell you: it is precisely because of the enthusiasm of unpaid blood donors that patients bear higher blood costs. Because of the huge profits from blood, the government It monopolizes blood collection channels. When there were no blood stations, the price of blood was 70 yuan per 200mm. The current price is about 200 yuan per 200mm. Moreover, blood donors used to have to be paid corresponding financial compensation, but now blood donation is free of charge, and no financial compensation is paid to blood donors.

In our hospital, the blood purchased from the blood station is really gold and silver. It doesn’t matter if we pay a penny less. These costs can only be passed on to the patients. In fact, we have nothing to do.

And due to the large number of unpaid blood donors, farmers and laid-off workers who used to sell blood to support the poor have now lost another way to make money. What a sin!

Someone said: Aren’t voluntary blood donors able to use blood for free? Yes, first go to the hospital to pay for the blood, then go to the hospital office to get a certificate, then find the doctor to sign it, take your ID card, medical record, surgery notice, and voluntary blood donation certificate, then go to the health bureau to get a stamp, and then Go to the blood station to apply for a refund, and pray that the person in charge will be there, and some places even stipulate that the patient must come in person to handle the refund! I saw many patients, but finally gave up going to the blood bank to refund the blood fee, thinking that I was out of luck. Others say: Donating blood can at least get free examinations. My person in charge told you that the blood bank only does the most routine blood and hepatitis B tests. There is even a report, but I have not verified it. Please take a look.

Finally, what is the attitude of the blood bank towards free first-come blood? It’s hard to say this. Anyway, hundreds of thousands of CC were dumped in Chengdu, and some of the blood was sold to pharmaceutical factories as raw materials. Basically, if there was any problem, it was dumped in batches. This kind of thing has not been exposed in every city. The people at the blood bank are basically all veterans of the military or people who are idle in society. Those who have graduated from medical schools are rare. The benefits are surprisingly good, with tens of thousands of bonuses at the end of the year. Each of those blood collection trucks costs millions. Believe it or not.
