Why is blood taken from the ring finger in terms of anatomy? Preparing to give a finger blood test
Why is blood taken from a ring finger? We will answer this question in our article. We will also tell you how the procedure itself takes the material and how to prepare for the study.
Every person, at least once in his life, turned to the laboratory for the delivery of such a blood test with a finger. This is the most common way to examine the condition of the body. When a person comes to take this test, the technician asks him to prepare a ring finger for blood collection. It is worth thinking about why it is the medical workers who ask him to stretch them in order to take the material for research out of it. It is also worth saying that the answer to such a question is not known even by some laboratory technicians.
Why is blood taken from a ring finger? Now we will understand this question.In fact, everything is not so difficult. The answer to the question of why blood is taken from a ring finger is associated with the anatomy of the hand. The fact is that when the material is collected, a person is punctured.
This means that the skin is damaged. If the skin is damaged, there is a possibility that an infection can enter the body through the resulting wound and the infection process begins. In order to prevent any foreign elements from leaking after blood collection, a person is given cotton wool soaked in an alcoholic solution. It needs to be fixed at the puncture site for a few minutes to ensure the disinfection process.

The structure of the human hand is arranged in such a way that if any infection gets into the human body through a nameless, middle, or index finger, then it has a certain time spread only there. As for the other two, namely the big one and the little finger, the infection will spread directly to the hand. If the infection gets into the hand, it can pass into the hand. As a result, the whole body may be infected.
Why is blood taken from the ring finger in terms of anatomy? The fact is that the nameless is less involved in any functions. Therefore, blood is taken from it. When the finger is not exposed to any external influences, it heals faster. Ring finger is not particularly active. Namely, he is minimally involved in processes such as typing on the keyboard, writing, and so on. The wound on it will heal faster than on the index or middle fingers.
How is blood taken?
How is the material collected for finger blood analysis? Blood is a unique material for determining the state of the body. Therefore, when a person goes to a medical facility, he is required to give blood for examination. Based on the data obtained from the laboratory, the doctor can make a diagnosis and prescribe an effective treatment that will lead to a speedy recovery of the patient.
A finger blood test is a very informative method that allows you to determine what kind of disorders the person has in the body. For example, an increased level of white blood cells indicates that an inflammatory process is underway.
This examination is called clinical or general.Blood taken from a finger also has a name. It is called capillary. Laboratory testing of the collected material determines the number of cells and their quality. There are indicators of the norm: in what quantities which cells should be present in human blood. If during a laboratory study it is revealed that there are deviations of any indicators upwards or downwards, then this means that there is a pathological process in the body. Perhaps there is inflammation or a tumor.
Blood analysis was done by absolutely all people, from newborns to the elderly. This method of determining the state of a person is basic. It allows you to quickly and effortlessly determine the patient's condition and draw conclusions about his state of health. Also, a blood test is mandatory for pregnant women, as it is very important to monitor the condition of the future mom when carrying a fetus. During this period, she is in a precarious position. Here we are talking about the state of the future mother and the normal development of the child.
How is blood test taken?
Fingerprinting for analysis is carried out by a special medical worker - laboratory assistant. He carries out this procedure with gloves. They protect it from blood on the skin, because patients who come to donate it may be infected with any diseases.
Therefore, a medical professional is obliged to protect themselves and them. Legislation does not require changing gloves after each procedure, as long as there is disinfection. Therefore, if a person is worried about the sterility of gloves, then he can take on his procedure and invite the technician to put them on before taking blood.
Preparation for blood test. What to do and what should not?
Before blood donation should be carried out special training. This is necessary for the analysis to be reliable. There are certain rules of preparation.
1. Blood should be donated on an empty stomach. Therefore, before this event, the last meal should be eight or ten hours.
2. A few days before the blood collection procedure, it is recommended to remove fatty and spicy foods from your diet. It is also worth refusing drinks that contain alcohol and other bad habits.
3. Do not exercise.It is advisable to limit yourself from any workload, even if they are related to work. Do not physically load your body before donating blood. Sports can affect the result of the analysis.
4. It is necessary to take care of the nervous system. Must be at rest. Since stresses and experiences also affect the blood. Because of what the result may be wrong.
5. You can not smoke before giving blood from a finger. This bad habit changes the indicators of analysis.
How to take the material?
How to take a complete blood count? There are two ways to collect material for the study of human blood:
- Rapid test to identify the amount of hemoglobin in the patient's blood. Also, this method allows to determine the level of ESR. Usually, rapid research is carried out when you need to get results as a matter of urgency. Such a case may occur during emergency hospitalization and preparing the patient for surgery.
- Normal laboratory blood sampling allows you to find out how much red and white cells, red blood cells, white blood cells and other trace elements are contained in human blood.
As mentioned above, blood is taken from the ring finger. How this is done, we have described in detail. In addition to the above reasons for taking blood from this particular finger, there is one more.
It is connected with the fact that the ring finger of the left hand (for right-handers) has thinner skin than the rest. Of course, this property is controversial. But such an argument has the right to exist. If we start from the fact that this finger is least involved in any actions, then it is possible that the skin on his pad is indeed more tender than on others.
We have found out how to prepare for the blood test. Note that the laboratory assistant works in gloves, which are treated with a special solution. According to the rules, of course, disposable instruments are used. They are unpacked directly by the patient. So the person who came to donate blood can directly control the issue of security. Now there are special lancets that hide the needle inside the case. Usually they are used for blood sampling in small children (up to three years). A very thin needle is inserted in these lancets, which makes the puncture practically painless. The baby will hardly feel any pain.
