The study of biological materials and especially blood is a common procedure prescribed for the diagnosis or in the process of treatment.
To avoid getting incorrect results, some rules must be followed before tests.One of them refers to the use of tobacco products.
Is it possible to smoke before taking blood?
For those who are undergoing to use tobacco products, the question is possible to smoke before the blood donation is very relevant.After all, it happens that a person and a few hours cannot spend without any other inflation.
Once in the body through the lungs, nicotine is almost immediately absorbed into the blood, changing its structure significantly.Moreover, it does not matter which cigarettes of cigarettes use a smoker.As a result, the analysis will show data that a doctor may interpret inadvertently and can lead to misdiagnosis.
This state of things is full of useless treatment, which means long-term disease, and in the worst case developing complications.
Attention!Doctors prohibit a smoking hour before the analysis, and in some cases (which the specialist will warn in advance), there may be more abstinence.
As for whether it is possible to smoke after giving blood, then limits are less strict, but they are still.From immediately after the blood fence, the person is weakened, and the flow of nicotine will increase the load on the body, it can lead to undesirable consequences.Immediately after blood donation, it is advisable to sit quietly for a few minutes, then eat something, drinks and only after that, remember the cigarette.
Effect on blood indicators
Explanation Why it is impossible to smoke before donating blood very simple - nicotine can affect most biomaterial indicators, especially:
- Change platelet properties;
- significantly increase cholesterol;
- affect the ratio of hormones;
- Change hemoglobin indicators;
- increase lymphocytes;
- Increase the contents of catecholamine and cortisol.
In addition, the sharp emission of catecholamine leads to the graphics and as a result of difficulty during the blood.Blood becomes thicker, the process of biomaterial fiction is complicated.
Nicotine negatively affects the process of providing oxygen internal organs.Starving oxygen that occurs as a result leads to deterioration in welfare.
General blood test
Smoking affects the general blood test, as a result of the fact that the development of inflammation or infection is possible.As a result of the reaction between hemoglobin and carbon monoxide, in the high concentration of cigarette smoke, carboxigyghoglobin is formed.
This substance, unlike protein, does not transport oxygen into tissues and organs.The hypoxia that inhabits causes excessive production of lymphocytes, and their increased blood content can be considered the presence of the inflammatory process in the body.Thus, the results of the general blood test, donated shortly after smoking, will be incorrect.
Attention!The maximum concentration of nicotine in the blood is achieved about half an hour after smoking, so before you donate blood from your finger, you must not smoke at least 1-1.5 hours, but it is better to increase this period.
Biochemical analysis
Biochemical blood test allows you to identify many internal pathologies, including the presence of cancer and a cardiovascular system disease.That is why it is so important to prepare for the study carefully, watching all the rules, including the smoking before donation of blood.
Venous blood is the desired material, thanks to the study that you can get a fairly complete idea of the body's condition.But for this results, the results must correspond to the actual state of work.
In the process of using tobacco products in the blood, not only redistribution of certain substances comes.Smokers change the metabolism of the lipid carbohydrate, which also affects blood indicators.Therefore, experts have expressed a ban before excursions from the vein blood are quite categorically.Abstinence should be a few hours.
Sugar analysis
Sugar analysis helps to detect such serious disease as diabetes.The answer to the question, you can smoke before donating blood for sugar, will also be negative.Scientists have proven that nicotine increases blood glucose.This fact, as well as change in other indicators, can cause misinterpretation of results.
If the patient has an already increased sugar level, even a single smoked cigarette can significantly worsen the situation.
Blood on HIV
When donating blood for HIV infection, it is forbidden to smoke.You have to leave cigarettes 2-3 hours before the process.Nicotine and other substances contained in the tobacco smoke inhibit the immune system.Therefore, the result of HIV analysis can be incorrect and does not show the patient's true state.
Hormones Research
The hormonal background is a very important indicator that affects the state and performance of the entire organism.Nicotine affects the adrenal glands, leading to increased hormone synthesis, especially cortisol.In addition, a man for smoking reduces testosterone production, and in women estrogen and prolactin.
Smoking before the hormone analysis can negatively affect the functioning of the thyroid gland.So it is desirable to leave a cigarette a few hours before jumping blood.
How does the donation affect?
Nicotine causes a change in a cell structure at the cell level, and also affects plasma.The person who decided to donate blood to help others undergo a mandatory exam.If the results are satisfactory, you can become a donor.
Since the blood is donated in a wide range of situations in which they wonder lives and death sometimes solved, its quality should be perfect.Therefore, by referring a future donor, the doctor speaks detail about all available prohibitions and restrictions.Including that it was announced at which time before the proceedings, alcohol (2-3 days) and cigarettes (at least 1 hour) must be rejected.
In the blood of avid smokers, nicotine and other harmful substances received in the smoking process are constantly present, because a person smokes with such a frequency that blood simply has no time to clean.Such persons may not be allowed to give to donate in the selection phase.
How to prepare a blood test smoker?
Before donating blood for analysis, you can't just smoke.In order for the results of the study to be absolutely reliable and give the actual idea of the patient's health, some preparation rules must be observed.They are as follows:
- The blood for the study is donated in the morning (from 8.00 to 11.00).This is due to the fact that the indicators are distributed during the day, and those obtained from the morning fence of biomaterials are used as average data.
- It is recommended that the blood is taken over by an empty stomach, and the interruption between the submission of biomaterials and the last meal can be 8 to 14 hours.This subject is due to the fact that food entering the body has an impact on the state of blood and hormone level.
- From smoking before the analysis, you should also refrain.You can smoke a cigarette at least an hour before donation of blood.But for some studies, the period of abstinence increases.
- Strong emotional shocks and physical activities should be avoided, as they can affect biochemical indicators and hormone levels.
- Be sure to warn the doctor about drugs taken.Maybe he will have to deny for an analysis for a while.
You should know, not just how much blood must not smoke before blood, but for a period to refrain from alcohol.For various studies, doctors call various expressions, but minimum - one day.
Habit and urine analysis
As for whether it is possible to smoke before urine analysis, doctors opinions are generally converged.Most experts are not recommended using tobacco products before taking urine.This is due to the fact that the chemicals present in tobacco affect the composition of urine and may distort the results obtained during the study.
Disagreements appear in how long it takes to pass after the smoked cigarette to the delivery of biological fluid.The main amount of nicotine and other harmful substances begins to filter the kidneys and settle in urine about 8 hours after entering the body.But tobacco starts its effect on the body almost immediately.
Tobacco ingredients, which enter the body, affect hormonal background, liver and other internal organs.It is therefore advisable not to smoke at least an hour before the analysis, but it is better to refrain from 10-12 hours.
Conclusion
Data obtained as a result of analysis can be incorrect due to recently smoked cigarettes.This will lead to the wrong diagnosis and accordingly, misrepresented treatment.But considering that regular smoking negatively affects the health and condition of the body, bad test results can reflect the right image and state available pathologies.
