Almost everyone knows that laboratory tests are carried out on an empty stomach. But few people know whether it is possible to drink water before donating blood. Usually doctors do not emphasize this important point. If the rules for drinking fluid are not properly followed before the analyzes, an incorrect result is possible. To assess the state of health of people and identify pathology at the initial stage, it is necessary to follow certain recommendations when donating blood.

What blood tests can a specialist prescribe?

For research, a small amount of lymph is taken and its composition is studied. To diagnose diseases, the doctor may prescribe some tests:

1. Almost everyone who has ever complained to a doctor is assigned a general check of the composition of the blood for preliminary diagnosis, and if there is any suspicion, then additional studies are assigned.
2. The practice of biochemistry allows a more in-depth study of the composition of the blood, to understand how the internal organs function, whether the metabolism is impaired. Then you can make a temporary diagnosis based on these indicators.
3. A sugar test is taken to measure the required percentage of glucose in the blood.
4. A study for hormones establishes the bioactivation of substances produced by the human glands. In this way, endocrine disorders, signs of infertility and other diseases can be detected.

It is also very appropriate to clarify the composition of plasma for tumor markers. This is an excellent way to determine oncology long before the onset of the primary signs of the disease.

The test detects HIV, hepatitis and other infections. Due to the influence of pathology, the composition of the blood changes, the level of glucose changes, inflammatory processes are triggered, the balance of hormones is disturbed and some internal organs cannot function normally. Therefore, it is very important to know if you can drink water before donating blood.

Preparation for laboratory processing of blood

Before issuing a referral for a particular analysis, the doctor notifies the patient about the need to follow the rules of preparation and accompanies the words with instructions in writing. If a person forgot to read it before collecting the analysis, he can familiarize himself with this data on the laboratory's billboard.

Plasma is taken in the morning on an empty stomach, because this time of day is most suitable for accurate research. On the eve of the event, it is advisable not to eat, so as not to affect the chemical formula of the blood. In this case, you need to clarify whether you can drink water before donating blood.

It happens that the plasma needs to be taken urgently. For example, if the patient is conscious, he is asked whether he has drunk and whether he has eaten recently.

It is important to understand that compliance with the requirements for blood sampling for analysis does not in any way infringe on the patient's rights. This is necessary for adequate results so that diagnostics can be carried out further.

Rules for collecting blood tests

3 days before lymph intake, it is not recommended to eat fried, fatty and spicy foods. It is also prohibited to consume alcoholic beverages.

Half a day before your exploration, you can enjoy a light meal for the last time. It can be both steamed vegetables and cereals and dairy products. You can not play sports, physically and emotionally overstrain.

Immediately before the analysis, it is suggested not to take pills or any other medications. If taking medication is vital for the patient, then you need to notify the laboratory assistant about this in advance. Sometimes some lymph samples require medication. For example, to measure the curve of sugar in hemolymph, it is prescribed to drink a little warm tea with added glucose before the analysis.

Other studies do not suggest drinking tea, coffee, compote and other drinks 12 hours before the procedure. In such situations, the doctor can confidently answer - no to the question: is it possible to drink water before donating blood. The only limitation is the general analysis of plasma: drinks of this type should not be drunk in the morning before the start of the study.

Is it allowed to drink liquid before donating blood?

Scientists have proven that ordinary water without minerals can radically change the composition of lymph. So, in order to answer the question - is it possible to drink water before donating blood, consider the options for various studies:

1. The water composition is unlikely to affect the general blood test. For some patients, before the procedure, doctors recommend drinking water in small sips to relieve nervousness. And for young children, drinking water is especially shown, because they cannot hide the desire for thirst. The main thing is that these are not carbonated, mineral and other drinks that can change the quantitative ratio of leukocytes in the blood.
2. Long before taking plasma for sugar, it is better not to drink liquid. But if you are thirsty, then a few sips will not harm and you cannot dilute glucose.
3. A biochemical blood test does not involve drinking water. This procedure is very precise and any intervention can affect the final result. This is especially prohibited if the goal is to diagnose the body's excretory system. Uric acid under the influence of fluid can significantly distort its readings.
4. When donating protein for hormones, it doesn't hurt to drink a few sips of clean water. You can also successfully clarify tumor markers and find viral diseases.
5. To indicate cholesterol in the blood, you must not drink liquid. For prolonged thirst, it is enough to moisten your lips with water. Drinks should be taken at least 12 hours before the scheduled procedure. This prohibition also applies to food.

Sometimes drinking a lot of water is harmful not only before the collection of tests. Hypertensive patients, for example, drinking plentifully on an empty stomach, are able to provoke a hypertensive crisis in themselves, which leads to an inevitable jump in pressure.

If there are any doubts about drinking fluids, then you need to ask your doctor about this in advance. It is considered inappropriate to clarify this issue in the office right before the study. After all, nothing can be changed. It is also worth worrying about the contents of the menu on the eve of blood sampling.
