2023 Turn the page Why do you have to draw blood when you go to the hospital?Doctor revealed!The blood drawn is gone!I believe that many people have had the experience that when they arrive at the hospital, whether it is to see a doctor or a physical examination, they often can't avoid one examination - blood drawing. So, why do you have to have blood drawn when you go to the hospital?The blood that was drawn out went to ** again?Today, let's unveil the mystery behind this.
1. Why do I have to take blood when I go to the hospital?
Diagnose the disease: Blood is an important part of the human body, and it contains a large number of biomarkers that reflect the health of the body. Through blood testing, doctors can understand the patient's physical condition, such as whether there is anemia, whether the number of white blood cells is normal, blood sugar, blood lipid levels, etc., so as to help doctors diagnose diseases.
Evaluate the effectFor some patients who need long-term treatment, such as diabetes, hypertension, etc., regular blood tests can help doctors evaluate the effect and understand the control of the disease, so as to adjust the plan in time.
Prevent disease: Through blood tests, some potential health problems can be detected early, such as abnormal liver and kidney function, elevated tumor markers, etc. This allows for early intervention and ** in the disease, thus reducing the risk of exacerbations.
Scientific researchSome of the blood samples will be used in scientific research to help the medical community better understand the pathogenesis and methods of disease. Of course, this needs to be done with the patient's consent.
Second, the blood drawn went to **?
Laboratory tests: Most blood samples are sent to a hospital laboratory for testing. Technicians in the laboratory will use a variety of advanced instruments and methods to detect and analyze various indicators in blood samples, and finally generate a detailed test report. This report is sent to the doctor as an important basis for diagnosing the disease and formulating the best plan.
Store for later use: Some blood samples may be stored for later use. This is mainly to deal with some special circumstances, such as abnormal initial test results that require re-examination, changes in the patient's condition and need to be re-evaluated, etc. In addition, some special blood samples (such as rare blood types, blood from patients with special diseases, etc.) may also be stored for long-term use for medical research or ** needs. Of course, these stored blood samples are strictly managed and protected to ensure their safety and privacy.
DisposalAfter testing and storage, blood samples that are no longer needed are disposed of as medical waste. During the processing process, the hospital follows strict regulations and standards to ensure that the blood samples do not pose a hazard to the environment and human health. This typically includes steps such as high-temperature disinfection, chemical treatment, etc., to completely eliminate pathogens and harmful substances from blood samples.
3. Several misunderstandings about blood drawing
Drawing blood can be detrimental to health: In fact, a normal blood draw has little to no effect on physical health. Because the amount of blood drawn at a time is relatively small (usually between a few milliliters and tens of milliliters), the human body can fully tolerate such a loss of blood volume. Moreover, after the blood is drawn, the body will quickly replenish the lost blood components and restore normal physiological functions.
An empty stomach is required before blood is drawn: While it is true that some blood tests need to be done on an empty stomach (e.g., blood sugar, lipids, etc.), not all of them do. Therefore, the need for fasting before blood drawing should be determined on a case-by-case basis. If you are unsure whether you need to fast, you can consult your doctor or** before the test.
Drawing blood can be painful: For many people, there is indeed some discomfort (such as pins and needles, slight pain, etc.) when blood is drawn, but this discomfort is usually short-lived and tolerable. And with the advancement of medical technology and the improvement of the operation level of medical staff, the blood drawing process has become faster and more comfortable.
4. How to reduce the discomfort during blood drawing?
Relax: Maintaining a relaxed and cheerful mood can help reduce discomfort during blood draws. You can relax by taking deep breaths and communicating with health care providers.
Choose the right puncture site: Different puncture sites feel different levels of pain. In general, the cubital fossa on the inside of the arm is one of the more commonly used puncture sites because it is more abundant and easy to fix. If you are particularly sensitive to a certain part or are worried about pain, you can communicate with the medical staff and choose a suitable puncture site for blood collection!In order to reduce the discomfort during blood drawing, the following measures can be taken: first, you can communicate with the medical staff to choose the appropriate puncture site to reduce the pain;Second, taking deep breaths and relaxing during the blood draw can help relieve tension;Finally, if you feel particularly unwell, you can let your health care provider know so they can make adjustments to ensure a smooth process and minimize discomfort. Through the implementation of these measures, the comfort of the blood drawing process and patient satisfaction can be effectively improved, and the optimization and improvement of medical services can be contributed.
In short, blood sampling in the hospital is one of the common and important links in the diagnosis and treatment process, it can provide doctors with important information about the patient's health status, so as to help doctors make accurate diagnoses and programs, and the blood samples drawn will play their due value after rigorous testing and evaluation, and ultimately serve the health and well-being of human beings
