The study of biological materials and in particular blood is a current procedure prescribed for diagnosis or in the processing process.
To avoid obtaining incorrect results, certain rules must be followed before tests.One of them concerns the use of tobacco products.
Is it possible to smoke before passing blood?
For those who use tobacco products on a continuous basis, the question of whether it is possible to smoke before blood donation is very relevant.After all, it happens that a person and a few hours cannot pass without another puff.
Once in the body through the lungs, nicotine is almost immediately absorbed into the blood, considerably modifying its structure.In addition, regardless of cigarette cigarettes used by the smoker.Consequently, the analysis will show data that can be inadvertently interpreted by a doctor and can lead to poor diagnosis.
This state of affairs is responsible for unnecessary treatment, which means a prolonged disease and, in the worst case, the development of complications.
Attention!Doctors prohibit smoking an 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 blood donation, the restrictions are less strict, but they are still.Since immediately after the blood closure, a person is weakened and the flow of nicotine will increase the load on the body, this can cause unwanted consequences.Immediately after the blood donation, it is advisable to sit calmly for several minutes, then to eat something, to drink and only after that, you remember the cigarettes.
Effect on blood indicators
An explanation of the reason why it is impossible to smoke before giving blood is very simple - nicotine is capable of influencing most of the biomaterial indicators, in particular:
- Change the properties of platelets;
- considerably increase cholesterol;
- influence the relationship of hormones;
- Modify hemoglobin indicators;
- Increase the level of lymphocytes;
- Increase the contents of catecholamines and cortisol.
In addition, a clear catecholamine program leads to spasms and due to the difficulty of the blood flow.Blood becomes thicker, the biomaterial fiction process is complicated.
Nicotine negatively affects the process of providing internal oxygen organs.Oxygen famine which occurred accordingly leads to deterioration in well-being.
General blood test
Smoking affects a general blood test, therefore, it is possible to identify the development of inflammation or infection.Due to the reaction between hemoglobin and carbon monoxide, in the high concentration of cigarette smoke, carboxyghemoglobin is formed.
This substance, unlike proteins, does not transport oxygen to tissues and organs.Hypoxy that occurs causes excessive production of lymphocytes, and their content increased in the blood can be considered as the presence of an inflammatory process in the body.Thus, the results of a general blood test, given shortly after smoking, will be incorrect.
Attention!The maximum concentration of nicotine in the blood is obtained about half an hour after smoking, so before giving blood to the finger, you should not smoke for at least 1-1.5 hours, but it is better to increase this period.
Biochemical analysis
A biochemical blood test allows you to identify many internal pathologies, including the presence of cancer and diseases of the cardiovascular system.This is why it is so important to prepare carefully for the study, by observing all the rules, including with regard to smoking before blood donation.
Venous blood is the most informative material, thanks to the study of which you can have a fairly complete idea of the condition of the body.But for this, the results of the analysis must correspond to the real state.
In the process of using tobacco products in the blood, not only the redistribution of certain substances occurs.Smokers modify the metabolism of lipid-glucids, which also affects blood indicators.Consequently, the specialists expressed the ban before leaving the blood of the vein quite categorically.Abstinence should be several hours.
Sugar analysis
Sugar analysis helps detect a disease as serious as diabetes.The answer to the question, you can smoke before giving blood for sugar, will also be negative.Scientists have proven that nicotine increases blood sugar.This fact, as well as a change in other indicators, can cause an incorrect interpretation of the results.
If the patient has an already increased sugar level, even a smoked cigarette can considerably worsen the situation.
Blood on HIV
During the blood donation for HIV infection, smoking is forbidden.You must abandon cigarettes 2 to 3 hours before the procedure.Nicotine and other substances contained in tobacco smoke inhibit the immune system.For this reason, the result of HIV analysis can be inaccurate and not display the real state of the patient.
Hormonal research
The hormonal context is a very important indicator that affects the condition and performance of the entire body.Nicotine affects the adrenal glands, which leads to increased hormone synthesis, in particular cortisol.In addition, smoking decreases the production of testosterone and in estrogen women and prolactin.
Smoking before analyzing hormones can negatively affect the functioning of the thyroid gland.It is therefore desirable to abandon the cigarette a few hours before the blood jump.
How does the donation affect?
Nicotine causes a change in blood structure in terms of cells and also affects plasma.A person who decided to give blood to help others undergo a compulsory examination.If the results are satisfactory, you can become a donor.
Since the given blood can be used in a wide variety of situations in which life and death problems are sometimes resolved, its quality should be perfect.Therefore, by instructing the future donor, the doctor speaks in detail about all the prohibitions and restrictions available.Including that it is announced at what time before the procedure, it is necessary to refuse alcohol (2-3 days) and cigarettes (at least 1 hour).
In the blood of a passionate smoker, nicotine and other harmful substances received in the process of smoking are constantly present, because a person smokes with such a frequency that the blood simply does not have time to clean.These people may not be allowed to be given at the selection stage.
How to prepare a smoker for a blood test?
Before giving blood for the 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 state of health, certain preparation rules must be respected.They are as follows:
- The blood for the study is given in the morning (from 8:00 a.m. to 11:00 a.m.).This is due to the fact that the indicators go during the day, and those which are obtained from the morning fence of the biomaterial are used as average data.
- It is recommended to take blood to take an empty stomach, and a rupture between the surrender of biomaterial and the last meal can last from 8 to 14 hours.This article is due to the fact that the food that enters the body has an effect both on the blood state and the level of hormones.
- From smoking before the analysis, it is also necessary to abstain.You can smoke a cigarette at least an hour before blood donation.But for some studies, the period of abstinence increases.
- Strong emotional shocks and physical activity must be avoided, as they can affect biochemical indicators and hormone levels.
- Be sure to warn the doctor of the drugs taken.Perhaps, for an analysis, they will have to refuse for a while.
You should know, not only for the amount of blood which should not be smoked before blood, but also for the period to abstain from alcohol.For various studies, doctors call different terms, but the minimum - one day.
Urine habit and analysis
To find out if it is possible to smoke before the analysis of the urine, the opinions of doctors converge mainly.Most experts do not recommend using tobacco products before taking urine.This is due to the fact that the chemicals present in tobacco affect the composition of urine and can distort the results obtained during the study.
Disagreements occur on the hour which should pass after a smoked cigarette until the delivery of organic liquid.The main amount of nicotine and other harmful substances is starting to be filtered by the kidneys and settles in the urine about 8 hours after entering the body.But tobacco starts its effect on the body almost immediately.
The tobacco ingredients, entering the body, affect the hormonal background, the liver and the other internal organs.Therefore, it is advisable not to smoke at least an hour before the analysis, but it is preferable to abstain for 10 to 12 hours.
Conclusion
The data obtained as a result of analyzes may be incorrect due to a recently smoked cigarette.This will result in an incorrect diagnosis and, therefore, poorly prescribed treatment.But since regular smoking negatively affects the health and body condition, the poor results of the tests can reflect the real image and indicate the available pathologies.
