The general or common analysis of a blood - on an empty stomach or not? Doctor's recommendations

Each person at one or another stage of life has to take various tests. This need not necessarily be due to the onset of any illness. It is desirable to go through this procedure for preventive purposes. In this case, in the presence of any disease, you can detect it at the initial stage, which increases the possibility of timely treatment. Among the many surveys that are offered to pass through to a person, the common blood test is most common . On an empty stomach or not, how to take it - this is a question that interests everyone who will visit the clinic.

It should be noted that in order to obtain accurate results, it is necessary to observe the rules on both sides. The laboratory assistant should follow the technique of collecting blood, and the patient - the rules of preparation for analysis.

Preparatory stage

To obtain the most accurate results and to avoid the need for a repeated visit to the clinic, the following conditions must be observed:

1. Abstain from smoking in the last two hours before the test. This requirement is connected with the fact that nicotine can cause spasm of peripheral vessels, which will complicate the access of blood to the extremities. As a result, the analysis data may be distorted. For the same reason, you should not drink strong tea or coffee before the blood donation procedure.
2. Do not eat fatty foods and alcohol on the eve of tests. These foods can cause increased cholesterol in the blood. And this, in turn, will affect the sedimentation rate of erythrocytes, which is determined in this analysis.
3. To prepare for the analysis of blood was complete, it is not recommended to take certain drugs that affect blood clotting. If you undergo a course of treatment at the time of blood donation, you must notify the doctor about it, and, if possible, postpone the date of the analysis.
4. Do not take this test during a viral infection, and also some time after it. The minimum period that must pass after recovery is 7 days. This requirement is connected with the fact that this disease affects the cellular composition of the blood, therefore, the results of the analysis will be unreliable.

Finger blood test

In addition to the general clinical picture, this analysis will help determine other indicators of changes in the body. As a rule, this is the initial stage of blood donation. If your attending physician reveals any deviations from the norm, the analysis will have to continue to find the exact cause of changes in the body.

So, in addition to the general clinical picture, the analysis of blood from the finger determines:

• The level of hemoglobin in the body;
• Presence of various infections (bacterial or viral);
• Blood sugar level.

These indicators can vary with the use of certain foods, exercise and drinking alcohol. That is why the question: "the general analysis of blood - on an empty stomach or not," should not stand. If you go to donate blood from your finger, you should eat no later than 8 hours before the procedure. In the case when the level of sugar is measured, it is recommended to abstain not only from food, but also from water and even chewing gum.

Blood test from vein

This method of blood sampling gradually completely replaces the first. To date, a general blood test can be taken not only from the finger, but also from the vein. However, the latter method is gaining popularity, as it provides a more complete clinical picture.

Thus, once donating blood, you can get the results of many tests, which is very convenient.

So, a blood test from a vein can be taken if you want to determine:

• Your blood group and Rh factor (this indicator can be detected when passing the analysis from a finger);
• Biochemical composition;
• Hormonal background;
• The presence of infections that are sexually transmitted;
• Level of oncomarkers.

It is noteworthy that before you take a blood test from a vein to all these indicators, you can not eat. An exception is the analysis for hormones TSH and paraormon. In addition, if you want to be tested for HIV infection, hepatitis or syphilis, doctors strongly recommend that you give blood exclusively on an empty stomach.

Hidden blood: a way of determining

Among the many studies that modern medicine offers, there is an analysis for latent blood. This is a method of examining the stool, which is done to detect latent bleeding from different parts of the gastrointestinal tract. This is an extremely important laboratory analysis that can diagnose the onset of various serious diseases that can not otherwise be detected.

To obtain reliable results, before submitting the analysis for hidden blood three days before the delivery of the material, it is necessary to exclude meat, fish, green vegetables and tomatoes from the ration. In addition, it is necessary to stop the use of any laxative drugs that can affect the work of the intestine. It should be remembered that the correctness of the result of the analysis depends on correct preparation, and therefore the correctness of the diagnosis.

Blood test for pregnancy

Waiting for a child is the most beautiful time in a woman's life. However, in addition to the joyful feeling of the origin of life, this period is characterized by the need for regular visits to the women's consultation.

With all the variety of tests that the expectant mother should take throughout pregnancy, the general analysis of blood and urine is regular. For professional supervision of pregnancy, it is necessary to take them at least once a month. In this case, if urine can be collected in the morning immediately after awakening, then the question "the general analysis of blood - on an empty stomach or not", is quite controversial.

Pregnancy is a period of life when a woman needs to regularly consume calories and such a long break between meals can adversely affect her health. Therefore, doctors are allowed a loose breakfast before donating blood. As for water, it can be drunk without restrictions.

General analysis of blood in children

Children are a category of patients that require a special approach. What does the child's blood test mean? This is a comprehensive diagnosis that allows you to determine the course of the child's development and the availability, both the diseases themselves, and the prerequisites for them.

The preparation procedure depends on the age of the small patient. If the child does not have a year, then there is no question of taking the tests on an empty stomach. The time that must necessarily be sustained from the moment of ingestion equals three hours. If you get longer - okay, but a three-hour interval is necessary.

Children from a year and up already need to try to explain the importance of this analysis and prepare for the procedure. Reception of blood tests in small patients is usually accompanied by negative emotions, which can lead to stagnation of blood, which, accordingly, complicates the procedure for its collection.

Therefore, it is extremely important to try to create a positive attitude in children, in which they will not be afraid of doctors and possible pain. Physical loads should be excluded the day before the visit to the clinic, and from the diet should be removed high-fat products. Immediately during the blood sampling itself, you must distract the baby. You can do this either by talking, or by your favorite toy. Observance of these recommendations will allow obtaining the most reliable results without psychological stress.

Where can I take a blood test?

If there is a need to donate blood, you have a choice between a state polyclinic, to which you are territorially treated and a private medical center. Everything depends on your desire and financial possibilities.

To date, there are many private laboratories that have the latest equipment. In this case, not everyone can afford to pay the required amount for the survey. In this case, you can contact the clinic, which is located on the territory of your residence.

The cost of a blood test

Those wishing to undergo a medical examination are interested in how much a blood test costs. The answer to this question depends on several factors, such as the choice of laboratory and the type of analysis. If there is a compulsory health insurance policy, you will do a free blood test in the state polyclinics. This applies to a medical facility located on the territory of your residence. If for some reason you want to take tests in another state polyclinic, the availability of the policy will provide free medical care.

As for private laboratories and medical centers, here the cost of each analysis depends on the price category that the institution establishes. For example, the price of a clinical blood test depends on the depth of the study. The cost varies from 150 to 650 rubles. The price of biochemical analysis from the vein is determined by the type of analysis: if the level of certain antibodies is examined, the cost is usually from 150 to 300 rubles. The prices of tests for hormones and oncomarkers start from 300 rubles. The determination of the presence of viral infections and the number of antibodies in the body costs about 400 rubles and depends on the complexity of the manipulation. In this case, the comprehensive delivery of blood for the presence of any infection, as a rule, allows you to save. In any case, choosing the place where you want to donate blood, you should familiarize yourself with the services provided and their cost in order to know the exact price you will have to pay for the procedure.

Conclusion

Thus, the surrender of blood is a procedure that every person who thinks about his own health should regularly attend. How to give a general blood test, fasting or not, depends on the state of health, the purpose of the examination and the disease being determined. In any case, if the doctor has appointed you to donate blood, you need to clarify what training requirements are required for a specific analysis.
