Only a blood test can tell whether some indicators are normal or not. Blood drawing can check many items. After centrifugation, the extracted blood enters the machine for testing. After completion, it will be treated as medical waste, which cannot be recycled and the quantity is too small. Some people say that the blood test sheet of the hospital has been sold, which is completely nonsense. It just means that it should be treated before testing and treated as medical waste after use, and the amount is too small. Usually only a few milliliters are taken, and everyone's blood type is different. How to recycle? Donate 300-400 ml. What can these ml do? The blood collected by blood donation needs a lot of testing and storage, and the cost is relatively high. It is not cost-effective to spend a lot of money on those milliliters, which is why blood donation is free, but blood transfusion needs to be paid, that is, the cost of testing and storage is high. Some people say that too much blood drawn in hospitals will affect health. In fact, don't worry, it takes 300-400 ml to donate blood. What effect can these milliliters make up for? So, why do hospitals draw blood to detect some disease-related indicators? Why always draw blood? Some indicators will change and need dynamic observation. Where did the blood end up? It is treated as medical waste.
1. Blood test can reflect many biochemical indexes of human body, which is helpful for doctors to judge the condition. For example, if you draw blood from a cold, you can judge whether it is bacterial infection or viral infection according to the different white blood cell indexes, so as to achieve the purpose of targeted treatment. Secondly, hospitals also have related medical requirements. Blood tests are helpful for disease diagnosis and avoid misdiagnosis.
2. The amount of blood drawn is actually not much, a few milliliters or so. The pump vessel is similar to a convex lens. It looks more, but it's actually very few.
3. After blood test, the remaining blood is harmlessly concentrated. The hospital has a perfect biochemical waste treatment process and will not circulate to the market or other places.
After checking the remaining blood, it will generally be kept for a few days for re-examination. There is a small horizontal line under the general inspection report: this result is only responsible for this specimen. After the storage period, it can be treated as infectious medical waste.
