The examination of biological materials and in particular the blood is a common process that is prescribed for the diagnosis or in the treatment process.
In order to avoid false results, some rules have to be followed before the tests.One of them concerns the use of tobacco products.

Is it possible to smoke before the blood test?
For those who are continuously using tobacco products, the question of whether it is possible to smoke from blood donation is very relevant.Finally, it happens that a person and a few hours cannot spend without another train.
As soon as the lungs in the body, nicotine is absorbed into the blood almost immediately, which significantly changes its structure.In addition, it does not matter which cigarette cigarettes were used by the smoker.As a result, the analysis shows data that can accidentally be interpreted by a doctor and can lead to incorrect diagnosis.
This condition is used with useless treatment, which means a lengthy illness and, in the worst case, develops complications.
Attention!Doctors prohibit smoking one hour before the analysis, and in some cases (which the specialist warn in advance), there can be more abstinence.
Whether it is possible to smoke after the blood donation, then the restrictions are less strict, but they are still.Since a person is weakened immediately after the bloodun and the nicotine flow increases the load on the body, this can lead to undesirable consequences.Immediately after the blood donation, it is advisable to sit quietly for a few minutes and then eat something, drink and only then on the cigarettes.
Effect on blood indicators
An explanation of why it is impossible to smoke blood before donating blood is very simple - nicotine can affect most biomaterial indicators, especially:
- Change the properties of platelets;
- significantly increase cholesterol level;
- influence the ratio of hormones;
- Change hemoglobin indicators;
- Increase the lymphocyte content;
- Increase the content of catecholamines and cortisol.
In addition, a sharp emission of catecholamines leads to a cramp and as a result of the difficulty of blood flow.The blood becomes thicker, the process of biomaterial fiction is complicated.
Nicotine has a negative impact on the process of providing internal organs with oxygen.The oxygen hunger, which was created by this, leads to a deterioration in the fountain.

General blood test
Smoking influences a general blood test, which is why it is possible to identify the development of inflammation or infections.As a result of the reaction between hemoglobin and carbon monoxide, carboxy ghemoglobin is formed in the high concentration of cigarette smoke.
In contrast to protein, this substance does not transport oxygen into tissue and organs.Hypoxia that arises provokes an excessive production of lymphocytes, and its increased content in the blood can be viewed as the presence of an inflammatory process in the body.Thus, the results of a general blood test that is donated shortly after smoking are wrong.
Attention!The maximum nicotine concentration in the blood is reached about half an hour after smoking.Before you donate blood from the finger, you shouldn't smoke at least 1-1.5 hours, but it is better to increase this time.
Biochemical analysis
With a biochemical blood test, you can identify many internal pathologies, including the presence of cancer and diseases of the cardiovascular system.For this reason, it is so important to prepare yourself carefully for the study and observe all the rules, including smoking before the blood donation.
Venous blood is the most informative material thanks to the study that you can get a fairly complete idea of the condition of the body.However, the results of the analysis must correspond to the actual condition.
When using tobacco products in the blood, not only the redistribution of certain substances occurs.The smokers change the lipid carbohydrate metabolism, which also affects the blood indicators.Therefore, specialists expressed the ban before leaving blood categorically from the vein.The abstinence should be several hours.
Analysis for sugar
The sugar analysis helps to recognize such a serious illness as diabetes.The answer to the question that you can smoke before donating blood for sugar will also be negative.Scientists have proven that nicotine increases blood sugar.This fact and a change in other indicators can lead to an incorrect interpretation of the results.
If the patient has an already increased sugar content, a smoked cigarette can also consider the situation considerably.
Blood on HIV
If you donate blood for HIV infections, it is forbidden to smoke.You have to give up cigarettes 2-3 hours before the procedure.Nicotine and other substances contained in tobacco smoke inhibit the immune system.For this reason, the result of the HIV analysis can be inaccurate and cannot indicate the patient's actual condition.

Hormone research
The hormonal background is a very important indicator that influences the condition and performance of the entire organism.Nicotine influences the adjoining greens, which leads to an increased synthesis of hormones, in particular cortisol.In addition, the smoking man reduces the production of testosterone and in women estrogen and prolactin.
Smoking before analyzing hormones can negatively influence the functionality of the thyroid gland.So it is desirable to give up the cigarette a few hours before the blood jump.
How does the donation affect?
Nicotine causes a change in the blood structure at the cell level and also influences plasma.A person who decided to donate blood to help others undergo 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 the problems of life and death are sometimes solved, its quality should be perfect.By instructing the future donor, the doctor speaks in detail about all available bans and restrictions.Including it is announced at the time before the intervention alcohol (2-3 days) and cigarettes (at least 1 hour) are rejected.
In the blood of an enthusiastic smoker there are constant nicotine and other harmful substances, since a person with such a frequency smokes that blood simply has no time to clean.Such people may not be donated in the selection phase.
How do I prepare a smoker for a blood test?

Before you donate blood for the analysis, you can not only smoke.So that the results of the study are absolutely reliable and give a real idea of the patient's state of health, some preparation rules must be observed.You are as follows:
- The blood for the study is donated in the morning (from 8 a.m. to 11 a.m.).This is due to the fact that the indicators are used as average data during the day and those who are preserved from the morning fence of the biomaterial.
- The blood is recommended to take an empty stomach and a break between the handover of biomaterial and the last meal can be between 8 and 14 hours.This object is due to the fact that the food that enters the body has both the blood disease and the hormonnage level.
- Smoking before analysis should also be desperate.You can smoke a cigarette at least an hour before the blood donation.However, the abstinence period increases for some studies.
- Strong emotional shocks and physical activity should be avoided because they can influence biochemical indicators and hormone levels.
- Be sure to wait the doctor in front of the medication taken.Maybe you have to reject a while for an analysis.
You should not only know how much blood should not be smoked in front of the blood, but for what time to avoid alcohol.For different studies, doctors call different terms, but the minimum - one day.
Habit and analysis of urine
With regard to the question of whether it is possible to smoke before analyzing the urine, the opinions of doctors mainly converge.Most experts do not recommend using tobacco products before taking urine.This is due to the fact that the chemicals present in tobacco influence the composition of the urine and distort the results obtained during the study.
Differences of opinion arise as to when a smoked cigarette should pass until biological liquids.The main amount of nicotine and other harmful substances begins by the kidneys and sets off in the urine about 8 hours after entering the body.But tobacco begins its effect on the body almost immediately.
Tobacco ingredients that enter the body influence the hormonal background, the liver and other internal organs.Therefore, it is advisable not to smoke at least an hour before the analysis, but it is better to do without 10-12 hours.
Diploma
Data received as a result of analyzes can be wrong due to a recently smoked cigarette.This leads to incorrect diagnosis and, accordingly incorrectly prescribed.In view of the fact that regular smoking has a negative impact on the health and condition of the body, poor test results can reflect the real image and specify the available pathologies.
