The study of biological materials and in particular blood is a common procedure prescribed for diagnosis or in the treatment process.
To avoid obtaining incorrect results, some rules should be followed before the tests.One of them is about using tobacco products.
Is it possible to smoke before you do your blood test?
For those who use tobacco products on a continuous basis, the question of whether it is possible to smoke before donating blood is very important.After all, it happens that a person and several hours cannot pass without another powder.
Once it is in the body through the lungs, nicotine is almost immediately absorbed into the bloodstream, significantly changing its structure.Moreover, it doesn't matter which cigarettes were used by smokers.As a result, the analysis will show data that can be inadvertently interpreted by a physician and can lead to a wrong diagnosis.
This state of affairs is fraught with useless treatment, which means a prolonged disease, and at worst, the development of complications.
Attention!Doctors stop smoking an hour before the analysis, and in some cases (which the specialist will warn in advance), may have more abstentions.
As for whether it is possible to smoke after donating blood, then the restrictions are less strict, but they are still.Since immediately after the blood fence, a person weakens and the nicotine flow will increase the load on the body, this can lead to undesirable consequences.Immediately after donating blood, it is advisable to sit calmly for a few minutes, then eat something, drink and only after that remember the cigarette.
Effect on blood indicators
An explanation of why it is impossible to smoke before donating blood is very simple - nicotine is able to affect most biomaterial indicators, in particular:
- change platelet properties;
- significantly increases cholesterol;
- affect hormone ratio;
- Change hemoglobin indicators;
- Increase lymphocyte level;
- Increase the content of catecholamines and cortisol.
Moreover, a sharp emission of catecholamines leads to spasm and as a result of the difficulty of blood flow.Blood becomes thicker, the process of biomaterial fiction is complicated.
Nicotine adversely affects the process of providing internal organs with oxygen.The oxygen hunger that arose as a result leads to a deterioration in well -being.
Overall blood test
Smoking affects a general blood test, as a result of which it is possible to identify the development of inflammation or infection.As a result of the reaction between hemoglobin and carbon monoxide, at the high concentration of cigarette smoke, carboxyhemoglobin is formed.
This substance, unlike protein, does not transport oxygen to tissues and organs.Hypoxia that gives birth provokes excess lymphocyte production, and their increased blood content can be regarded as the presence of an inflammatory process in the body.Thus, the results of a general blood test, donated immediately after smoking, will be incorrect.
Attention!The maximum concentration of nicotine in the blood is reached about half an hour after smoking, so before donating blood from your finger, you should not smoke for at least 1-1.5 hours, but it is best to increase this period.
Biochemical analysis
A biochemical blood test allows you to identify many internal pathology, including the presence of cancer and diseases of the cardiovascular system.That is why it is so important to prepare the study carefully, observing all the rules, including in terms of smoking before blood donation.
Venous blood is the most informative material, thanks to the study of which you can get a very complete idea of body condition.But for this, the results of the analysis must correspond to the real state of work.
In the process of using blood tobacco products, not only the redistribution of certain substances occurs.Smokers change lipid-carbohydrate metabolism, which also affects blood indicators.Therefore, specialists expressed the prohibition before leaving blood from the veins quite categorically.The abstinence should be several hours.
Sugar
Sugar analysis helps detect such a serious illness as diabetes.The question of the question, you can smoke before donating blood for sugar, it will also be negative.Scientists have proven that nicotine increases blood glucose.This fact, as well as a change in other indicators, can cause an inaccurate interpretation of the results.
If the patient has an elevated sugar level, then even a smoked cigarette can significantly aggravate the situation.
HIV
When donating blood for HIV, it is forbidden to smoke.You should abandon cigarettes 2-3 hours before the procedure.Nicotine and other substances involved in tobacco smoke inhibit the immune system.Because of this, the result of the HIV analysis can be incorrect and does not exhibit the true condition of the patient.
Hormone
Hormonal background is a very important indicator that affects the condition and performance of the whole organism.Nicotine affects adrenal glands, which leads to increased hormone synthesis, in particular cortisol.In addition, smoking man reduces testosterone production, and in estrogen and prolactin women.
Smoking before analyzing hormones can adversely affect the functioning of the thyroid gland.So it is desirable to abandon the cigarette a few hours before the blood jump.
How does the donation affect?
Nicotine causes a change in blood structure to cell level, and also affects plasma.A person who decided to donate blood to help others suffer a mandatory examination.If the results are satisfactory, you can become a donor.
Since donated blood can be used in a variety of situations in which issues of life and death are sometimes resolved, its quality must be perfect.Therefore, by instructing the next donor, the doctor speaks in detail about all available stops and restrictions.Included is notified in which hour before the procedure it is necessary to reject alcohol (2-3 days) and cigarettes (at least 1 hour).
In the blood of a thirsty smoker, nicotine and other harmful substances taken in the smoking process are constantly present, as a person smokes with such frequency that blood simply does not have time to cleanse.Such people may not be allowed to be donated at the selection phase.
How to prepare a smoker for a blood test?
Before donating blood for analysis, you can not only smoke.In order for the results of the study to be absolutely reliable and give a real idea of the patient's health status, some rules of preparation must be respected.They are as follows:
- Blood for the study is donated in the morning (from 8.00 to 11.00).This is due to the fact that indicators vary during the day, and those obtained from the biomaterial morning fence are used as average data.
- It is recommended to take an empty stomach, and a break between the delivery of the biomaterial and the last meal can be from 8 to 14 hours.This article is due to the fact that the food that enters the body has an effect on both blood and hormone levels.
- From smoking before analysis, it should also be contained.You can drink a cigarette at least an hour before donating blood.But for some studies, the period of abstention increases.
- Strong emotional shocks and physical activity should be avoided, as they can affect biochemical indicators and hormone levels.
- Be sure to warn your doctor about the medication taken.Perhaps, for an analysis, they will have to refuse for a while.
You need to know, not only how much blood should not smoke before blood, but for which period to refrain from alcohol.For various studies, doctors call different terms, but at least a day.
Habit and urine analysis
Regarding whether it is possible to smoke before urine analysis, the opinions of doctors mainly converge.Most experts do not recommend using tobacco products before receiving urine.This is due to the fact that the chemicals present in tobacco affect the composition of the urine and can distort the results obtained during the study.
Disputes arise at what time it should go after a smoked cigarette until the distribution of biological fluid.The main amount of nicotine and other harmful substances begins to be filtered by the kidneys and placed in the urine about 8 hours after entering the body.But tobacco begins its effect on the body almost immediately.
Tobacco ingredients, entering the body, affect the hormonal background, liver and other internal organs.Therefore, it is advisable not to smoke at least an hour before the analysis, but it is best to refrain for 10-12 hours.
cONcluSiON
The data obtained as a result of the analysis may be incorrect due to a recent smoked cigarette.This will lead to an incorrect diagnosis and, accordingly, the treatment described incorrectly.But given that regular smoking adversely affects the health and condition of the body, poor test results can reflect the true appearance and show the pathologies available.
