There is no person who has never donated blood from a finger or from a vein. For the prevention of diseases or just to assess the general condition of the body, it is recommended to do this regularly. That's why everyone needs to get familiar with blood donation tips. If you follow these simple recommendations, you will get the most reliable test results. Everyone knows that it is necessary to donate blood early in the morning, in the interval from 8 to 9 hours. And it’s better to do this on an empty stomach, which means 8 hours before the analysis, you must definitely refrain from eating food. But many are concerned about the question of whether it is possible to drink water before donating blood?
To drink or not to drink ...
The answer to this question depends on what kind of analysis you are going to carry out, since the individual requirements for blood donation are considered the same in most laboratory tests, and in some cases options are possible, it depends on the particular case. So, they take blood for an "empty stomach" for biochemical analysis, for HIV and AIDS, for hormonal reactions and some others. At this time, you can not drink carbonated drinks, which contain sugar or its substitute, tea or coffee drinks. But to the question of whether it is possible to drink water before donating blood in the case when you need to take the above tests, experts respond positively. Unsweetened drinking water does not affect the results of such studies.
What is not recommended on the eve of blood donation?
Experts advise a couple of days before the proposed blood test to review your diet and exclude fried and fatty foods, spicy foods, sauces and seasonings from it, and of course, do not drink alcoholic beverages. In the event that there was a reason, and a person nevertheless consumed such products, then it is advisable to postpone the analysis for a couple of days, since the result in this case may be unreliable. Half an hour before the laboratory test, it is forbidden to smoke, but you can drink water before donating blood.
When is the analysis taken from a vein?
Tips for passing an analysis from a vein are somewhat more complicated than from a finger. But to comply with them, of course, is necessary, because only then can we count on a true result. On the eve of blood collection, it is advisable to eliminate the load, sports training from the daily routine, and avoid a surge of emotions and nervous tension. Specifically, on the eve of the blood collection itself, you just need to sit and achieve a state of rest. From this, breathing will return to normal and will not affect the result. If a person who is going to donate blood is treated with medication, then he must tell the doctor about everything before analysis. Because when many drugs are mixed with blood particles, a reaction occurs in the human body, and this can distort the results of the study. In this case, blood from a vein must be taken either before the start of therapy, or after its completion.

If you still have doubts about whether you can drink water before donating blood, then it is better to check with your local doctor who writes out the directions for tests, or in the laboratory in which you are going to be examined.
