The study of biological substances and especially blood for diagnosis or treatment is prescribed in the process of treatment.
Some rules must be followed before the tests to avoid incorrect results.One is about the use of tobacco products.
Can you smoke before you have a blood test?
For those who are constantly using tobacco products, it is very relevant to the question of whether it is possible to smoke before the blood donation.After all, one person and a few hours cannot spend without another puff.
In the body, nicotine is absorbed almost immediately into the blood through the lungs, significantly changing its structure.In fact, no matter what smoker's cigarette cigarette used.As a result, the analysis presents data that a doctor can accidentally interpret and lead to a poor diagnosis.
This situation is full of useless treatment, which means a protracted disease and, in the worst case, develop complications.
Attention!Doctors prohibit smoking one hour before the analysis and in some cases (which is warned by a specialist in advance) can be greater abstinence.
As a matter of fact, it is possible to smoke after donation of blood, then the restrictions are less strict, but still there are.Since a person weakens just after the blood fence and the flow of nicotine increases the load of the body, this can have undesirable consequences.Immediately after donation of the blood, it is advisable to sit calmly for a few minutes, then eat something, drink, and then remember the cigarette.
Effect on blood indicators
Explaining why it is impossible to smoke before donation of blood is very simple - nicotine can influence most biomated indicators, especially
- change the properties of platelets;
- significantly increases cholesterol;
- affects the proportion of hormones;
- Change the hemoglobin indicators;
- increase the levels of lymphocytes;
- Increase the content of catecholamines and cortisol.
In addition, sharp emissions of catecholamines lead to cramps and difficulty in blood flow.The blood becomes thicker and the process of biomated fiction is complicated.
Nicotine negatively affects the process of securing internal organs with oxygen.The starvation of oxygen, which has resulted as a result, leads to deterioration in the well.
General blood test
Smoking affects the overall blood test, which results in the development of inflammation or infection.As a result of a reaction between hemoglobin and carbon monoxide, carboxy -ghemoglobin is formed in high concentrations of cigarette smoke.
Unlike protein, this substance does not deliver oxygen to the tissues and organs.Hypoxia that arises provokes excessive production of lymphocytes and is considered to be the presence of an inflammatory process in the blood in the blood.Thus, the results of the general blood test, which are donated shortly after smoking, will be incorrect.
Attention!The maximum concentration of nicotine is reached in the blood about half an hour after smoking, so that before donating your finger, you should not smoke for at least 1-1.5 hours, but it is better to increase this period.
Biochemical analysis
Biochemical blood test allows many internal pathologies, including cancer and cardiovascular disease.Therefore, it is so important that we are carefully prepared for the study, observing all the rules, including pre -blood -donated smoking.
Venous blood is the most informative substance that allows you to get a fairly complete picture of the body condition.But for this, the results of the analysis must meet the real situation.
Not only the use of tobacco products in the blood is redistributed.Smokers change lipid carbon hydrate metabolism, which also affects blood indicators.Therefore, professionals have said the ban before leaving the blood categorically from the vein.Abstinence should be several hours.
Analysis of sugar
Sugar analysis helps to detect a serious illness such as diabetes.The answer to the question is that you can donate blood to sugar, it will also be negative.Scientists have shown that nicotine increases blood sugar.This change and change in other indicators can cause incorrect interpretation of results.
If the patient already has increased sugar levels, even a smoked cigarette will deteriorate significantly.
Blood on the HIV
If you donate blood to HIV infection, it is forbidden to smoke.You must leave the cigarette 2-3 hours before the procedure.Nicotine and other substances in tobacco smoke inhibit the immune system.As a result, the result of HIV analysis may be inaccurate and cannot present the patient's real condition.
Researching hormones
The hormonal background is a very important indicator that affects the condition and performance of the entire body.Nicotine affects the adrenal glands, which leads to synthesis of increased hormones, especially cortisol.In addition, smoking people reduce the production of testosterone, estrogen and prolactin women.
Smoking can negatively affect thyroid function before analyzing hormones.So it is desirable to leave the cigarette a few hours before the blood jump.
How does the donation affect?
Nicotine is influenced by the blood structure at the cell level and also affects the plasma.A person who has decided to donate blood to help others will undergo a mandatory examination.If the results are satisfactory, it can become a donor.
Because donated blood can be used in many situations, when the questions of life and death are sometimes resolved, its quality must be perfect.Therefore, with the instruction of the future donor, the doctor will discuss in detail about all the available prohibitions and restrictions.Including when to refuse alcohol (2-3 days) and cigarettes (at least 1 hour) before the procedure.
In the blood of enthusiastic smoking, nicotine and other harmful substances are constantly present, as people smoke with such frequency that the blood simply does not have time to clean.Such people may not be allowed to donate in the selection phase.
How to make smokers for blood tests?
Before donating blood to the analysis, you can not only smoke.In order to ensure that the results of the study are completely reliable and give a real picture of the patient's health, some preparation rules must be followed.These are the following:
- The test is donated in the morning (between 8am and 11.00).This is due to the fact that indicators are held during the day and are used as average data from the morning fence of biological material.
- Blood is recommended to take an empty stomach and the break between biological materials and the last meal can be 8-14 hours.This element is due to the fact that the food entering the body affects both blood disease and hormones levels.
- You should also refrain from smoking before the analysis.You can smoke a cigarette at least one hour before donating your blood.However, in some studies, the abstinence period 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 drugs you take.Perhaps they have to deny an analysis for a while.
You should know that not only because you should not smoke blood in front of the blood, but also alcohol.For different studies, doctors call different conditions, but the minimum - one day.
The habit and analysis of urine
To be able to smoke before urine analysis, doctors' opinions are primarily converging.Most experts do not recommend using tobacco products before taking urine.This is due to the fact that chemicals in tobacco affect the composition of the urine and distort the results obtained during the test.
The disagreements arise from the amount of time after the smoked cigarette until the biological fluid occurs.The main amount of nicotine and other harmful substances are filtered by the kidneys and after entering the body for approx.8 hours into the urine.But tobacco starts almost immediately on the body.
The tobacco ingredients that enter the body affect the hormonal background, liver and other internal organs.Therefore, it is advisable to smoke at least one hour before the analysis, but it is better to stay for 10-12 hours.
Conclusion
The data obtained as a result of the analysis may be incorrect due to the recently smoked cigarette.This results in an incorrect diagnosis and, accordingly, incorrectly prescribed treatment.However, since regular smoking has a negative effect on the health and condition of the body, poor test results may reflect the real picture and indicate the pathologies available.
