General blood analysis. Where do they take blood from children and adults with a general blood test

A general blood test is the most common way of diagnosing any disease. When a person turns to the clinic for examination, the doctor will definitely give him a referral for blood donation. This is done to see if there are any deviations from the norm in the patient's body. You should know that only the medical worker can decipher the analysis. But approximately to estimate or appreciate results of the analysis it is possible independently, if to know norms of the maintenance of those or other components of a blood.

Indications

When a person is given a referral to a blood test?

• To diagnose and determine the patient's treatment regimen, the doctor gives directions to a general blood test. Where a biological material is taken, the doctor also determines.
• If a person is to plan a planned placement in a hospital, he will certainly need to hand in the material for investigation in the laboratory.
• Before carrying out the vaccination, a referral to the general blood test is also prescribed. Where the biological material is taken from children, it will be considered below.
• Before prescribing a course of treatment with medications, the patient should be given blood for examination in the laboratory. This is done to identify any contraindications for taking certain medications.

Blood test: where do they get the material and how is the fence made?

Usually, blood sampling for laboratory analysis is taken from an anonymous finger. But there are variants when the blood will have to be delivered from the vein. Such a need arises if an expanded study is needed. Where a common blood test is taken from adults, the attending physician determines.

The sampling of biological material for the laboratory is done according to the following algorithm. The finger is smeared with an alcohol solution. Further, the lab assistant makes a puncture and takes the material into the tube. Then the blood moves into a glass flask. A small amount of it is left on a special glass. This is done for the purpose of a detailed study of the material and for making a general blood test. Where do they get the material from?

When for analysis it is required to take blood from the patient's vein, the person is pulled by the forearm with a special tourniquet. The skin on the arm in the elbow is lubricated with alcohol solution. After the needle is injected into the vein. Then the material is taken, which is also placed in a special flask, and a small amount is taken on the glass. There is a statistic that during a lifetime a person gives blood from the finger about 20 times.

General analysis of blood in children. Where do they take the material from the babies. Features of this study

It should be remembered that the values of the blood studied in infants differ from the norms of an adult.

The first fence for young children is prescribed at the age of three months. It is believed that in this age period, children are at risk of developing a disease such as iron deficiency anemia. Therefore, to identify the development of this disease, refer to the general analysis of the blood in the baby. Where do they get the material, the pediatrician points out. Here the doctor pays attention to the level of hemoglobin and erythrocytes.

Also from three months the child needs to be vaccinated. For its successful conduct, it is necessary that the child is healthy. This analysis provides an opportunity to know if all the indicators are normal.

Analysis in children

For older children, you need to take a blood test for an empty stomach. And for pectorals, this recommendation can be disregarded.

The material is taken by the laboratory assistant in sterile gloves using disposable instruments. Blood in children, as in adults, is taken from the fourth finger of the hand, if you count it from the big one. First, a fence is used to study the level of hemoglobin in the blood and ESR. Then, a material is collected to determine the number of leukocytes and red blood cells in the blood. Then the smears are placed on the slide. They are needed for the study of cellular composition.

It happens that parents are nervous when a child is assigned such a procedure as a blood sampling for analysis. This is not necessary, because the emotional state of an adult is passed on to the baby and he can begin to cry. Therefore, parents are advised not to be nervous and in a calm state to come for the analysis. If necessary, the laboratory assistant will consult how to keep the baby and where the blood is taken from a general blood test.

Results of laboratory examination

According to the data obtained from the laboratory, the doctor sees if there are any deviations in the human body. When an adult or child has any problems, the doctor prescribes further examination of the patient and gives direction to the narrow specialists. The results of the analysis obtained in the laboratory show the number of leukocytes, erythrocytes, platelets. Still revealing the level of hemoglobin and ESR. The leukocyte formula is also calculated.

Indicators

And what does each indicator mean? Let's consider them:

• Erythrocytes are red corpuscles in a person's blood. Their function is that they deliver oxygen from the lungs to all organs and tissues.
• ESR. расшифровывается как скорость оседания эритроцитов. This abbreviation stands for the rate of erythrocyte sedimentation. These data refer to one of the main parameters by which the presence or absence of the inflammatory process in the body can be determined.

• Leukocytes. If their level is raised, then there is some kind of infection or inflammatory process in the body. It can also mean that there are tumor processes, for example, oncology. Leukocytes are a constituent of the immune system. If their level becomes higher, then it means that the body starts to fight with some disease. White blood cells are white blood cells.
• Platelets. These cells are considered the smallest. They are colorless and responsible for blood clotting. Their number can vary within a day and after physical exertion.

Some Important Points

There are certain levels of blood in the above cells. Usually they are indicated in the form of the result of the analysis. Therefore, the patient himself can find out if he has the content of certain cells. But the exact interpretation of the analysis can only be given by a doctor.

Patients who are afraid to take the material out of the finger for some reason, may ask the doctor if it is possible to take a general blood test from the vein.

Conclusion

Now you know how a common blood test is done, where the material is taken from. We also talked about the features of collecting material from an adult, a child and a baby.
