The diagnostic procedure in the form of testing requires compliance with the rules. This is the only way to get the most reliable picture of the state of the organism. The accuracy of the results is influenced by many factors. We will find out if it is allowed to smoke before donating blood, and how nicotine affects the test results.

Basic postulates

The blood circulating through the closed system of blood vessels is about 6-8% of the mass fraction in the open system of the human body. This humoral fluid has many functions:

• transport;
• respiratory;
• regulatory;
• protective.

It consists of plasma, shaped elements, its composition is constantly changing under the influence of internal and external factors. This is a liquid connective tissue that is permanently renewed, has the property of instantly reacting to any transformations - the supply of nutrients, efforts, emotions.

You can find various answers to the question of what interval should be between taking blood and smoking a cigarette. But there is no variation in the answer to the question of whether it is allowed to smoke before donating blood, there is only one, and it is negative.

As for tobacco products, it does not matter either their shape, or the flavoring or the name of the company, and what it will be - hookah, electronic cigarettes or smoking herbs. The goal of the smoker is the consumption of nicotine, and he distorts objective data in any quantity, makes the doctor, when deciphering the analysis, assume non-existent pathologies and not see the real ones, analyze the deviations caused by the harmful compound instead of the real picture.

All recommendations regarding the requirements for preparing for the delivery of laboratory tests are based on scientific research. With regard to tobacco products and alcohol, the bans are especially categorical, since nicotine and ethanol have a negative effect on the natural composition of the biological fluid, greatly distorting the data obtained.

The effect of nicotine on performance

Smoking in different people causes similar transformations in the composition of the blood, since this is how an alkaloid acts on any organism:

• the level of eosinophils and neutrophils is rapidly falling;
• the concentration of cortisol and catecholamines increases;
• biochemical substrates appear in the bloodstream;
• the level of red blood cells rises and the number of leukocytes falls;
• hormones are released to neutralize the resulting toxic compounds;
• blood viscosity increases, its structure changes.

Similar processes occur throughout the body, so the same answer will be to the question of whether it is possible to smoke before donating blood from a finger or for a general analysis. This also applies to tests for the detection of antibodies and biochemical analysis.

Blood is taken for research to obtain reliable data. A smoker who cannot curb his need for an alkaloid distorts them, no matter if he does it out of ignorance or deliberately.

Blood biochemistry

A correctly submitted biochemistry analysis helps to identify pathologies of internal organs and systems. This is the most informative of the existing methods, on its basis it is possible to determine oncological pathologies, disorders in the work of the cardiovascular system, gastrointestinal tract and GBS. Changes in the metabolism of lipids, carbohydrates, cholesterol and hemoglobin indicators are the inevitable consequences of every smoked cigarette.

Therefore, answering the question whether it is possible to smoke before donating blood from a vein, not only is a categorical demand to stop smoking sounded, but the period during which the prohibition must be observed is prolonged. In this case, it is at least several hours before a sample of biological fluid is taken from the venous vessel.

UAC

General analysis is also informative. It is no coincidence that such a study is mandatory. It usually becomes the basis for preliminary assumptions, determining the direction in which certain indicators will be studied.

Biomaterial can be collected from a capillary (finger puncture) or from a vein. Therefore, here, too, there is only a negative answer to the question of whether it is possible to smoke before donating blood from a finger. This technique allows:

• count the number of red blood cells (growing after the consumption of nicotine);
• to identify the number of leukocytes (witnesses of inflammation, artificially underestimated by the action of a toxic compound);
• to assess the content of hemoglobin (lowered in a smoker and giving grounds to assume anemia).

If you do not quit smoking when testing for donation, it will change the biochemistry of plasma, and quite significantly. And this can subsequently potentially affect the life and health of the recipient.

Antibody test

The requirements for such a biomaterial are very strict, since the method still assumes inaccuracies. A smoker who does not take a break for at least two hours before donating biomaterial from a vein for antibodies risks not only his own life and health, receiving a false-positive or false-negative result. The decision to vaccinate, recover, or the presence of a pathogen depends on this.

It also endangers other people, since a distorted analysis for antibodies to coronavirus from a vein may not reveal the fact of infection, a potential source of infection will continue to spread virions among relatives, friends and simply strangers who are nearby.

Correct preparation for a blood test certainly includes quitting smoking at least 1.5-2 hours before sampling the biomaterial. Ideally, such a refusal should be made for 12 hours, or even for a day.

Outcomes

A negative answer to the question of whether it is possible to smoke before donating blood can be found in any instructions for passing the tests, no matter what method they are used for, and from wherever they are taken. This is the same immutable truth, as well as the fact that before examining the humoral fluid, one should not eat, be nervous and engage in physical activity.

Blood is an important biological fluid that is constantly changing under the influence of endogenous and exogenous factors. Her research allows you to get an idea of the state of human health. It is no coincidence that giving up food, smoking and alcohol, physical effort and emotions is positioned as an important condition for obtaining reliable data.

Nicotine affects blood elements, hemoglobin and sugar levels, and even antibody levels. Before taking the analysis, you must definitely quit smoking, preferably for a long time.
