Studies of biological and in particular blood are a common procedure prescribed for diagnosis or in the treatment process.
To avoid getting the wrong results, some rules must be followed before the test.One of them concerned the use of tobacco products.
Is it possible to smoke before taking a blood test?
For those who use tobacco products continuously, the question of whether it is possible to smoke before blood donation is very relevant.After all, it happens that someone and a few hours cannot be spent without any other puff.
Once in the body through the lungs, nicotine is almost immediately absorbed into the blood, significantly changes its structure.Moreover, it doesn't matter that cigarettes are used by smokers.As a result, the analysis will show data that may be accidentally interpreted by a doctor and can lead to a wrong diagnosis.
This condition is full of useless treatments, which means persistent disease, and in the worst case, develop complications.
Attention!Doctors prohibit smoking an hour before the analysis, and in some cases (which specialists will warn in advance), there may be more abstinence.
For whether it is possible to smoke after blood donation, it is less strict, but they are still.Since shortness of the blood fence, a person is weak, and nicotine flow will increase the burden on the body, this can cause unwanted consequences.Immediately after blood donation, it is advisable to sit quietly for a few minutes, then eat something, drink and only remember the cigarette.
Effect on blood clots
Explanation of why it is impossible to smoke before donating blood is very easy - nicotine can affect most biomaterial indicators, in particular:
- change platelet properties;
- significantly increase cholesterol;
- affect the ratio of hormones;
- change hemoglobin indicators;
- increase lymphocyte levels;
- Increase the content of catecholamines and cortisol.
In addition, sharp discharge of catecholamines leads to cramps and due to difficulty in blood flow.Blood is thicker, the biomaterial fiction process is complicated.
Nicotine has a negative effect on the process of providing internal organs with oxygen.Oxygen starvation that arises as a result leads to deterioration in well -being.
A general blood test
Smoking affects general blood tests, as a result it is possible to identify the development of inflammation or infection.As a result of the reaction between hemoglobin and carbon monoxide, in high concentrations of cigarette smoke, carboxyghemoglobin is formed.
This substance, unlike protein, does not transport oxygen to tissues and organs.Hypoxia that arises causes excessive lymphocyte production, and increased blood content can be considered as the presence of inflammation in the body.Therefore, the results of the general blood test, which are contributed immediately after smoking, will be wrong.
Attention!The maximum concentration of nicotine in the blood is reached about half an hour after smoking, so before you donate blood from your fingers, you cannot smoke for at least 1-1.5 hours, but it is best to increase this period.
Biochemical analysis
Biochemical blood tests allow you to identify many internal pathologies, including the presence of cancer and cardiovascular system diseases.That is why it is important to prepare carefully for this study, observing all the rules, including smoking before blood donations.
Venous blood is the most informative ingredient, thanks to a study that you can get a complete idea of your body condition.But for this, the results of the analysis must suit the actual situation.
In the process of using tobacco products in the blood, not only the redistribution of certain substances occurs.Smokers change lipid-carbohydrate metabolism, which also affects blood clots.Therefore, experts voice the ban before leaving blood from its veins.The abstinence should be a few hours.
Sugar analysis
Sugar analysis helps detect serious diseases such as diabetes.Answer to that question, you can smoke before donating blood for sugar, as well as negative.Scientists have proven that nicotine increases blood glucose.This fact, as well as changes in other indicators, can lead to incorrect interpretations of the results.
If the patient has an increased sugar level, a cigarette smoking can worsen the situation.
Blood on HIV
When donating blood for HIV infection, it is prohibited from smoking.You need to leave cigarettes 2-3 hours before the procedure.Nicotine and other substances contained in tobacco smoke prevent the immune system.Therefore, the results of HIV analysis may be inaccurate and do not display the actual condition of the patient.
Hormone research
Hormone background is a very important indicator that affects the condition and performance of the whole organism.Nicotine affects the adrenal gland, leading to increased hormone synthesis, especially cortisol.In addition, smoking men reduce testosterone production, and in estrogen and prolactin women.
Smoking before analyzing hormones can affect the function of the thyroid gland.Therefore, it is advisable to leave the cigarette a few hours before the blood jump.
How does the donation affect?
Nicotine causes changes in blood structure at the cell level, and also affects the plasma.Someone who decides to donate blood to help others undergo compulsory examinations.If the result is satisfactory, you can be a donor.
Because the blood donated can be used in a variety of situations where the issues of life and death are sometimes resolved, the quality should be perfect.Therefore, by directing future donors, doctors speak in detail about all the restrictions and restrictions available.Including it was announced at the time before the procedure was necessary to refuse alcohol (2-3 days) and cigarettes (at least 1 hour).
In the blood of a false smoker, nicotine and other harmful substances received in the smoking process are always present, as a person smokes with such a frequency that blood does not have time to cleanse.Such people should not be allowed to be donated at the election stage.
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 truly reliable and to give a real picture of the patient's health status, some of the preparation rules must be complied with.They are as follows:
- Blood for study is donated in the morning (from 8.00 to 11.00).This is due to the fact that the indicator revolves during the day, and that is obtained from the biomaterial morning fence is used as average data.
- Blood is recommended to take an empty stomach, and rest between biomaterial delivery and the last meal can be from 8 to 14 hours.This item is due to the fact that food entering the body has an effect on both blood conditions and hormone levels.
- From smoking before analysis, one must also hold back.You can smoke at least an hour before blood donations.But for some studies, the abstinence period increases.
- Strong emotional shock and physical activity should be avoided, as it can affect biochemical guidance and hormone levels.
- Be sure to warn your doctor about the medications taken.Perhaps, for analysis, they need to push for a moment.
You should know, not only for how much blood cannot be separated before the blood, but for what period of cannot hold from alcohol.For various studies, doctors call different terms, but minimum - one day.
The habits and analysis of urine
About whether it is possible to smoke before urine analysis, the doctor's opinion is mainly gathered.Most experts do not recommend using tobacco products before taking urine.This is due to the fact that the chemicals contained in tobacco affect the composition of the urine and can distort the results obtained during the study.
Disputes arise about the time that needs to pass after smoking cigarettes until the delivery of biological fluid.The main amount of nicotine and other harmful substances begin to be filtered by the kidneys and settle in the urine about 8 hours after entering the body.But tobacco begins its effects on the body immediately.
The ingredients of tobacco, enter the body, affect the background of hormones, liver and other internal organs.Therefore, it is advisable not to smoke at least an hour before the analysis, but it is best to hold back for 10-12 hours.
Conclusion
The data obtained as a result of the analysis may be incorrect because of this new cigarette.This will lead to the wrong diagnosis and, thus, improper treatment.But as smoking regularly affects the health and condition of the body, poor test results can reflect the true picture and show the pathology.
