The epidemiological situation can hardly be called favorable, so many people are forced to take laboratory tests. Humoral fluids, biological secretions are one of the most important sources of information about the state of human health. Understanding the responsibility of the diagnostic measure, patients are interested in the nuances of the procedure, for example, whether it is possible to drink water before donating blood, and whether this will affect the test result.

Preparation for laboratory research methods

The Ministry of Health has developed rules for preparing for diagnostic tests, which clearly state what should not be done before conducting laboratory tests. Under the ban there are many familiar processes that start the daily life of the human body.

Some of the conditions relate not only to morning exercise, but also to a diet for several days, taking medications, and bad habits. There is also an answer to the question whether it is possible to drink water before donating blood, and whether this can affect the result.

It is prohibited to use any liquid containing food components, dyes and preservatives, tannin, caffeine and alcohol - including tea, coffee, compote, kefir, soda, uzvar, any alcoholic drinks, milk and dairy products, as well as:

• eat food at least 8 hours before biochemical and serological tests;
• 12-hour fasting is imperative before elucidating lipid profile data;
• unsweetened tea and a light breakfast can be consumed no later than an hour before the procedure, when the UAC is given;
• even exclude physical activity and emotional arousal before taking venous blood.

In general, tests for iron and hormones can be taken only in the morning, because it is at this time that the necessary indicators can be identified.

All this is aimed at achieving an important goal - the purity of laboratory material for research, the reliability of the data of the analysis.

More about blood tests

Blood performs numerous functions in the body, and its indicators are examined by a variety of methods, each of which is aimed at obtaining specific data. None of the laboratory studies is so informative, none of the biological fluids and secretions of the body is studied by so many methods. This indicates the importance of the data received.

The composition of the blood can be transformed from physical effort, stress, food and fluid intake. There are rules that apply to certain types of research that affect the indicators. Water can be allowed or prohibited before a certain type of analysis:

• donating for hormones, you can drink a small amount of water, but not carbonated or mineral water, but simple boiled, settled or filtered;
• conducting a biochemistry test means that even a small amount of a harmless liquid can lead to distortions of important indicators, cause unreasonable fears;
• before donating blood for sugar, drinking water is undesirable, but if you really want to, then a little is possible;
• UAC does not mean a ban on drinking, children can be given a couple of sips, and adults too - in this case there will be no effect on the data.

In order not to remember separately the prohibitions before diagnostic procedures, there is a simpler rule: if they take blood from a vein, you should not drink before the analysis. If you plan to take blood from a finger, the water will not affect in any way. The same rule applies to tests for tumor markers and infectious pathogens, especially since these procedures are not pleasant, and it will not hurt to moisten a throat dry from excitement.

Outcomes

1. Drinking water is undesirable when studying venous blood - liquid can distort the study data.
2. You can drink before tests for infections, tumor markers and hormones, as well as if the blood is tested for sugar.
3. Before donating blood, you must certainly observe other restrictions - food, physical activity, emotional overexcitation.
4. Data corruption can lead to unforeseen consequences.
