In the context of modern medicine, blood collection is a basic and important diagnostic tool. For doctors, mastering the skills of blood collection and the order of blood collection is a prerequisite for accurate diagnosis. For the majority of patients, understanding the importance of blood collection and how to cooperate with blood collection is also the key to ensuring health.
Blood collection, as the name suggests, is to collect a certain amount of blood sample by puncturing the vein for laboratory testing to assess the patient's health status, diagnose diseases, monitor the effect, etc. Although blood collection is a simple task, it contains a lot of medical knowledge. For example, the order of blood collection is strictly regulated.
First of all, we need to understand the basic process of blood collection. Before blood collection, the doctor will choose the appropriate blood collection site according to the specific situation of the patient, and the commonly used ones are the important vein, cephalic vein and femoral vein of the elbow. Then, the doctor will disinfect the blood collection site, use a lancet to puncture the vein, and when the blood flows into the blood collection tube, pull out the lancet and gently press on the blood collection site to prevent bleeding. Finally, the doctor will mark the blood collection tube and send it to a laboratory for testing.
So, how is the order of blood collection determined? The determination of the blood collection sequence is mainly based on two principles: one is to ensure the accuracy of the blood collection results, and the other is to improve the efficiency of blood collection. According to these two principles, the order of blood collection generally follows the following rules:
First, a whole blood sample should be collected before a serum sample. A whole blood sample is a blood sample containing anticoagulants that is used to test hematological markers such as hemoglobin, white blood cells, platelets, etc. Serum specimens refer to blood samples that do not contain anticoagulants and are used to test biochemical and immunological indicators, such as liver function, kidney function, blood glucose, thyroid function, etc.
Secondly, blood collection tubes without additives should be collected first, and then blood collection tubes with additives should be collected. The blood collection tubes without additives are mainly used to collect whole blood specimens, while the blood collection tubes with additives are mainly used to collect serum specimens. The role of the additive is to prevent the blood sample from clotting and keep the blood in a liquid state for easy detection.
In addition, the patient's condition and laboratory requirements should also be considered when collecting blood, and sometimes the blood collection sequence needs to be adjusted according to the specific situation of the patient to ensure the accuracy and reliability of the blood collection results.
In the concept of traditional Chinese medicine, blood is an important material basis of the human body, which is a nutrient-rich red liquid that runs in the veins, which is called"Blood"。The function of blood is mainly to nourish and nourish the whole body, including complexion, muscles, muscles and bones, etc., and the way to exert its role is to distribute the whole body through the vasculature. Therefore, the proper functioning of blood is essential for the health of the human body.
Traditional Chinese medicine believes that the normal functioning of blood depends on the pumping function of the heart and the relaxation function of the vasculature. The heart can pump blood normally, and the vasculomotor function is coordinated, so that the blood can function normally and play its role in nutrition and moisturization. If the heart's pumping function is weakened, or the vasomotor function is dysfunctional, it will lead to blood flow disorders, blood stasis, bleeding and other problems.
Traditional Chinese Medicine**Blood diseases mainly promote the normal operation of blood by adjusting the function of the heart and vasculature. Commonly used methods are: blood circulation and blood stasis, blood nourishment and dryness, hemostasis, etc. Drugs that promote blood circulation and eliminate blood stasis, such as salvia, safflower, peach kernel, etc., can promote blood circulation and eliminate blood stasis. Blood-nourishing and moisturizing medicines, such as angelica, rehman, wheat winter, etc., can nourish the blood, moisten dryness and quench thirst. Hemostatic drugs, such as white grass, crane grass, palm bark, etc., can stop bleeding.
In short, whether it is blood collection in Western medicine or blood diseases in traditional Chinese medicine**, it is necessary to deeply understand and master relevant medical knowledge. Only in this way can we better serve patients and protect human health.
