Preparation for the test of tests.

Not every person, when he is going to do an examination, thinks about whether it is allowed to use water before the examination itself. Let's figure it out together with this sufficiently important issue.

Is it possible to drink water before passing a general blood test from vein, sugar, hormones, biochemistry?

There are several varieties of blood test. The simplest two analyzes are considered - general and biochemical. Housing stomach - this requirement is not considered the only one before the blood donation for analysis. Doctors put forward their special requirements to the biochemical examination.

Many patients, before donating blood for analysis, are wondering - is it possible to use water before such an examination? Before donating blood, of course, doctors do not prohibit drinking water, but do not oblige to do this. The liquid can be consumed as usual, but only in 30 minutes. Until the examination.

Doctors advise children to drink fluid 2 or 3 hours before the blood test in the amount of 2 glasses. This requirement is permitted if there is a one -time blood fence for several tests.

As a result, the blood becomes not so viscous, therefore, it will be much easier to obtain the right amount of blood for examination. If we talk about other liquids, such as tea, coffee, fruit drinks, juice, then they are allowed only after the procedure, because they can affect the chemical components of the blood itself.

In addition, before the examination, it is not recommended to visit the sauna with the bath, since these procedures greatly affect the body and its condition, as well as the blood. It is advisable to try to avoid those factors that can provide physical and psychological stress before leaving blood: bathing in the hole, hardening procedures, a contrast shower.

Separately, it is worth mentioning drinking alcohol. They, of course, are contraindicated. Alcohol is forbidden to drink at least three days before the procedure. After all, it is for this period that an alcoholic product is removed from the body.

In addition, drinking alcohol has a very strong effect on biochemical components of blood, and also on the number of leukocytes. Therefore, if the patient drank a certain dose of alcohol before blood donation, his result will be wrong. Alcohol, usually:

• Increases the concentration of lactate
• Increases the presence of triacillycerins
• Reduces the number of sugar contained in the blood

The final result of the blood can still affect medicationsthat the patient uses, especially hormonal drugs and antibiotics. Many of these drugs cause leukopenia and anemia. In addition, antibiotics sometimes affect blood coagulation, the number of platelets and the biochemical composition of the blood. For those patients who plan to undergo treatment with antibiotics, it is better to donate blood for analysis before the course or 7 days after treatment.

If the patient drinks drugs that need to be drunk on an empty stomach, then it is advisable for him to take the analysis until the tablets are used. If it is not advisable to put off the use of tablets, then it is better not to do this. But it is imperative to warn the doctor about this when he will interpret the results.

Now consider the recommendations that must be observed before blood donation for biochemistry.

• It is forbidden to do some physical exertion before the examination
• It is better to abandon any type of food 12 hours before blood donation
• You can not drink alcohol, smoke, take drugs, especially antibiotics
• Eliminate the use of any type of liquid

Why do not doctors advise drinking water before handing over 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, using a lot of water on an empty stomach, can thereby increase pressure and worsen overall well -being. This, no doubt, will have a great influence on the result and its reliability.

No doctor can say a clear and accurate answer to the question of how the fluid affects the content of blood. If you are touched by this problem and you do not know how to be, just consult in advance with your doctor, who will take blood from you for examination.

Is it possible to drink water in front of an ultrasound of the abdominal cavity, kidneys, liver, FGDS, FGS, EGDS of the stomach?

Preparatory processes for the behavior of ultrasound of the abdominal cavity, FGDS, FGS, and the EGDS of the stomach are quite responsible processes. In order for them to be made correctly, you need to know about whether it is possible to use clean water and other liquids before such examinations. After all, one day in life almost every person passes at least one of these examinations.

Can you drink water before an ultrasound?

First, consider how it is necessary to prepare for an ultrasound. The preparatory process itself should begin about 4 days before the start of the examination. Of course, for such a long time it is impossible to completely eliminate the liquid from your own diet, but some easy rules should be fulfilled.

The purified water must be drunk throughout the day in small sips and in small quantities. The volume of the recommended water for use should be a minimum of 1.5 liters per day. Water should enter the body either before eating, or after 30 minutes. After its use.

Before examining, doctors are strongly advised to at least 1 hour try to refrain from eating a liquid of any kind. Thus, we draw conclusions how exactly it is allowed to drink water before the start of the examination:

• During the preparatory diet before conducting an ultrasound, you can drink 1.5 liters of water per day, but not less
• It is not advisable to drink water immediately after eating
• Liquids can be drunk a little, but often
• Before examining for 1.5 hours, it is advisable not to drink fluids at all

If these tips are correctly observed, the result from the examination of the ultrasound will be as reliable as possible. If you violate these rules, then the examination will bring the wrong result.

But for what reason is it undesirable to drink water before an ultrasound? The answer is simple. Large use of fluids, like food with alcohol, can provoke gas formation in the inside of the abdominal cavity. But this factor can be an obstacle during the examination.

Before starting an ultrasound, the patient’s intestines should be completely empty. There are a lot of reasons for this. We will consider the most common of them:

• Due to water, an increased formation of gases may occur.
• Due to the liquid, cramps may occur.
• The human digestive system can perceive the liquid drunk as food and begins to actively function because of it. This may interfere with the correct examination.

In the event that there is strong heat outside, it is advisable not to drink water at least for an hour. It is better to replace drinking a moisturized napkin and attach it to the skin.

After the ultrasound, it is also better not to drink any liquids. Water must begin to be consumed gradually and small siples.

As mentioned above, before the ultrasound, it is necessary to carefully prepare the body. During this process, the patient should use a sufficient amount of water per day.

A certain amount of water can be replaced with ordinary tea. However, it should be remembered that before ultrasound, tea can only be drunk.

We will summarize how to drink tea correctly before the examination:

• Tea should be light, hard to drink is forbidden
• Tea during consumption should be well cooled
• Sugar and natural honey cannot be added to the drink
• It is not recommended to drink a lot of tea in front of the ultrasound
• It is better not to use tea after eating

Is it possible to drink water in front of the FGDS and FGS of the stomach?

Many patients are very worried about this issue. Before the examination itself, it is advisable not to drink any drinks at all, even clean water. Drinking clean water is allowed no later than 2 hours before the start of the examination, and custard weak tea no later than 4 hours.

It is not advisable to drink milk, since in this case it is equated with food. The best option is a complete rejection of fluid over the past 4 hours before the procedure.

Children are very difficult to cope with a sense of thirst. Therefore, if the child wants to drink just before the examination, then it is necessary that he rinse the mouth of the mouth with cold water, but at the same time does not swallow the liquid.

Is it possible to drink water in front of the EGDS of the stomach?

Doctors categorically prohibited Suppose drinks such as coffee, black tea and other other drinks before this examination. With a very strong thirst, you can drink 100 ml only purified non -carbonated water in 3 hours before the examination. Alcohol, even low alcohol, for example, beer, is strictly prohibited.

Is it possible to drink water in front of a colonoscopy in the morning?

Thanks to this method, the doctors can eliminate polyps, the size of which is not more than 1 mm. Also, the colonoscopy allows you to make an express examination, which makes it possible to find out whether it is a pre-elect newbiela or not.

Despite the fact that the patient feels discomfort during the examination, this technique is considered absolutely safe and high -precision.

In order for the examination to show the most accurate results, the patient needs thorough preparation and implementation of some rules. Only by observing the doctor’s recommendations and adhering to special rules can you get the most reliable diagnosis, and prescribe the correct treatment.

How is preparation for colonoscopy? It is as follows - the intestines must be thoroughly cleaned to obtain accurate and effective visualization. Consequently, it is recommended to use a godless diet before examination, take laxative drugs and conduct cleansing enemas.

Some patients are still worried about what question is: “Is it possible to drink water in front of a colonoscopy in the morning?” There are some requirements, for example, the fluid must be transparent, since staining the colon mucosa can become an obstacle to the doctor to detect pathological changes. Therefore, before the examination, it is allowed to drink water or weak tea in small quantities.

Before conducting a colonoscopy, the doctor may prescribe a special diet. It should include water, low -fat broths and teas. It is allowed to use liquids during the preparatory process as much as you like, but still desire to observe the following proportions:

• Drink filtered, clean water - 2 liters per day
• Drink tea - from 4 to 5 cups
• Drink broth (meat, fish, vegetable) - no more than 500 ml per day.
• Drink juice (you can not grape and plum), compote (only one that does not have a thick), jelly.

The last meal should be 2 o’clock in the afternoon on the eve of the examination. After this period passes, it is recommended to drink slightly sweetened tea (preferably green), mineral water, juice, non -carbonated drink). At 3 o’clock in the afternoon you need to drink 3 tbsp.
