Can I drink alcohol before taking a blood sample and the amount of days

Medical blood tests – a necessary step for the diagnosis of any disease. More than 60 % of the information on the human health, the doctor discovers the results. Get false data leads to the formulation of a diagnosis wrong, and, therefore, for the selection of the ineffectiveness of the therapies. This can lead to the aggravation of the severity of the disease and put in danger the life of the patient.

The accuracy and reliability of the results depends not only on the correct application of the methods of the analysis of the blood, but also about how to prepare correctly the patient before the delivery of the biomaterial (blood) for laboratory studies.

Can I drink alcohol before donating blood?

Information about the which for many blood tests coming into the laboratory should be in the morning on an empty stomach, is known to many people since childhood. Often, however, the information about the can I drink alcohol before taking of biological material (blood) for the analysis? patient informed.

Important: it is strictly forbidden to consume alcohol-containing beverages before taking the blood to the diagnosis.

In order to know how many days before the donation of blood for research should not drink alcohol? you have to understand at the time of the elimination of alcohol from the human body. The time needed for the complete removal of the decomposition products of alcohol, varies from a few (beer-4-6 %) and 18 to 20 hours (cognac 42 %). The time given for portions of 500 ml. In the case of taking large doses of time, metabolism increases.

According to these data, the recommended time that should pass after the last consumption of alcohol and spend the biomaterial is of 72 hours. In other words, if the patient is night, it is strictly prohibited to make donations of blood in the morning. You should postpone the visit to the laboratory at least 1 day.

The effect of alcohol in tests

Alcohol has a different effect on the functioning of all the systems and tissues. Disrupts the endocrine system, resulting in the definition of the state hormonal the patient may not be reliable. Nervous system directly or indirectly regulates that occur in the body's physiological processes and biochemical reactions. In turn, the ethanol slows down the nervous system innervation that influences the analysis of blood.

It is well known that the ethyl alcohol and products of its decay can significantly distort the results of the analysis biochemical. In addition, the products of the metabolism of the alcohol disrupts the enzyme system, which also leads to an incorrect laboratory diagnosis.

Often patients are interested in can I drink beer and weak alcoholic drinks before taking the blood for analysis? Definitely not as in beer as any other drink with alcohol drink, no alcohol.

Blood sugar and alcohol

The concentration of glucose (sugar) varies over the course of the day. Depends on the dishes that was used for the patient before the analysis, as well as a number of physiological factors. Alcohol has a direct effect on the liver, when there is not enough enzyme activity that is observed intoxication acute of the whole organism.

It is known that alcoholic drinks contain large amounts of carbohydrates, fissile in simple sugars and calories. The table of the average content of carbohydrates and calories for different types of alcohol.

Drink (100 grams) Strength % Carbohydrates (100 g) Calories (Kcal per 100 g)
Vodka 40 0 240
Brandy 0,7 220
Whiskey 0 225
Cognac 0,5 245
Punch 30-35 25-30 260-280
Liquor 25 55 350
Port 20 15 170
Vermouth 15 20 160
White wine 12-13 0,5-10 65-100
Red wine 5 80
Beer 4-6 3-5 50-65
before giving blood can I drink alcohol or not

For delivery of a biomaterial to determine the level of glucose in the interval the minimum amount of time without alcohol should be 48-72 hours. In the case of obtaining results, deviating from normal values, the analysis was repeated 2-3 times. Once the limit has no diagnostic importance, as it can be caused by a variety of reasons physiological.

Biochemical analysis and ethyl alcohol

The set of biochemical parameters allows to estimate:

  • the liver, kidneys, pancreas and the digestive system;
  • the state of the protein, the carbohydrate and fat metabolism;
  • the extent of the negative impact of the selected treatment methods and medications.

Change the functioning of the enzymatic system as a result of the alcohol exposure leads to incorrect survey data. It should be noted that long-term binge man is not enough with two days to remove from the organism alcohol and products of its decay. In this case, it is recommended to complete the detoxification procedure, which has as its goal the purification of the bodies of the toxic products of the metabolism of ethanol. To get the results that reflects accurately the state of health of the patient must be taken biochemical analysis, and not before 7 to 10 days.

Before the evidence of alcohol allowed?

With the exception of the tests, which are carried out with the purpose of establishing the fact of alcohol consumption by humans, for example, the reference to the work. In this case, no special training is necessary.

In the diagnosis of sexually transmitted diseases, in some cases, the doctor asks to use a small amount (100 ml) of alcohol in the evening prior to the visit to the laboratory. This fact is due to the fact that ethanol has a stimulating effect on the production of secretions of the genital organs. This simplifies greatly the procedure of taking of biological material for further studies.

Important: it is strictly forbidden to consume alcohol-containing beverages before taking the blood from the vein.

This is especially important the General rule for the analysis of blood, biochemical systems, and at the time of diagnosing HIV, syphilis and hepatitis b and C.

Rules for the preparation

Proper preparation for delivery of biomaterial includes not only abstinence from alcohol and a range of activities.

For 8-12 hours it is recommended not to eat, but for 1 day to give fatty and salty foods. This fact is explained by the fact that in the process of digestion aktiviziruyutsya enzymatic system, and therefore, the concentration of enzymes. A change in the balance of proteins, fats and carbohydrates have an impact on the physical parameters of the blood. To change the transparency, viscosity and blood cell composition lead to incorrect evaluation of analytical instruments and, therefore, unreliable data.

In addition, to the neglect of this rule leads to the increased risk of hemolysis (breakdown of red blood cells) from the blood into the test tube after taking. This is the reason for the mandatory cancellation of a research laboratory, and the need of re-making material.

Allowed to drink non-carbonated water without sugar in unlimited quantities. This will greatly facilitate the procedure of taking blood from a vein. The special importance of the rule is to properly prepare children for the tests.

The impact of a large number of drugs on the human body that is located in laboratory tests. However, much depends on the state physiological of the person (the speed of your metabolism, the presence of pathology of systems and organs), so that it is impossible to give a certain forecast of changes in the results of the test. Recommended for 2 days to stop taking the medication and according to the doctor. In case of impossibility of the abolition of essential medicines, it is important to warn them in the laboratory.
