  • Not every person, when going to do a survey, thinks about whether it is allowed to consume water before the survey itself. Let's look at this important issue together.

    Can I drink water before giving a general blood test from a vein, sugar, hormones, biochemistry?

    There are several types of blood test. The simplest are two analyzes - general and biochemical. An empty stomach - this requirement is not the only one before giving blood for analysis. To the biochemical examination of the doctor put forward their own special requirements.

    Many patients, before donating blood for analysis, are asked whether it is possible to consume water before such a survey? Before donating blood, of course, doctors do not forbid drinking water, but they do not oblige it either. The liquid can be consumed as usual, but only for 30 minutes.up to the survey.

    To children, doctors advise drinking fluids 2 or 3 hours before taking a blood test in the amount of 2 glasses. This requirement is resolved in the event that one-time blood sampling is required for several analyzes.

    Is it possible to drink water before taking

    tests? Because of this, the blood becomes less viscous, therefore, getting the right amount of blood for examination will be much easier. If we talk about other liquids, such as tea, coffee, fruit juice, juice, they are allowed only after the procedure, because they can affect the chemical components of the blood itself.

    In addition, before the examination is not recommended to visit the sauna with a bath, because these procedures greatly affect the body and its condition, as well as the blood. It is advisable to try to avoid the factors that can exert physical and psychological stress before donating blood: swimming in the ice-hole, hardening procedures, contrast shower.

    Separately it is necessary to mention the use of alcoholic drinks. They, of course, are contraindicated. Spirits are forbidden to drink at least three days before the procedure. After all, it is during this period that an alcohol product is taken from the body.

    In addition, the use of alcohol has a very strong influence on the biochemical components of the blood, and on the number of leukocytes. Therefore, if a patient drank a certain dose of alcohol before donating blood, his result would turn out to be wrong. Alcohol, usually:

    • Increases lactate concentration
    • Increases the presence of triacylglycerols
    • Reduces the amount of sugar that is contained in the blood

    The final result of blood can still be affected by medications , which the patient consumes, especially hormone drugs and antibiotics. Many of these drugs cause leukopenia and anemia. In addition, antibiotics sometimes affect blood clotting, the number of platelets and the biochemical composition of the blood. Those patients who plan to be treated with antibiotics, it is better to give blood for analysis before the course or 7 days after treatment.

    Soaking up the liquid affects the result of the

    tests If the patient drinks medications that need to be drunk on an empty stomach, then it is advisable to take the test before using the tablets. If it is not desirable to delay the use of tablets, then it is better not to do so. But it is necessary to warn the doctor about it when he will interpret the results.

    Now consider the recommendations that must be observed before donating blood to biochemistry.

    • It is forbidden to do any physical activities before the examination
    • It is better to give up any type of food 12 hours before the blood donation
    • Do not drink alcohol, smoke, take medication, especially antibiotics
    • Exclude the use of any kind of liquid

    Why doctors do not advise drinking waterbefore surrendering to biochemistry? The fact is that the liquid itself does not affect the blood test itself in any way. But those people who have hypertension, eating a lot of water on an empty stomach, can thereby increase their pressure and worsen overall well-being. This, without a doubt, will have a big impact on the result and its reliability.

    Does the water drench on the results of the

    analyzes? No single doctor in this area can say a single and precise answer to the question of how the liquid affects the blood content. If you are affected by this problem and you do not know how you should be, just consult in advance with your doctor who will take your blood for examination.
