Research on biological materials and especially blood is a common process prescribed for diagnosis or during treatment.
To avoid inaccurate results, some rules must be followed before the tests.One of them involves the use of tobacco products.
Can smoking before a blood test?
For those who use tobacco products on the basis of continuous, the question can smoke before donating blood is very suitable.In the end, that happened was a person and a few hours could not be for no other puff.
When in the body through the lungs, nicotine is almost absorbed into the blood, significantly changing its structure.Moreover, it is not a cigarette problem used by smokers.Therefore, the analysis will display data that may accidentally be explained by a doctor and can lead to wrong diagnosis.
This condition is full with useless treatment, which means a prolonged disease, and in the worst case, developing complications.
Attention!Doctors banned smoking an hour before analysis, and in some cases (which experts will warn), there may be more abstinence.
Regarding whether or not to smoke after donating blood or not, the limitations are less stringent, but they still have.Because right after the barrier, a person weakened and the nicotine flow will increase the load on the body, which can lead to unwanted consequences.Immediately after donating blood, should calmly sit for a few minutes, then eat something, drink and just remember tobacco.
Affect blood indicators
An explanation of the reason why not smoking before donating blood is very simple - Nicotine can affect most biological materials, especially: Special::
- change the properties of platelets;
- significantly increased cholesterol;
- affecting hormone ratio;
- change the hemoglobin index;
- increase the level of lymphocytes;
- Increase the content of catecholamines and cortisol.
In addition, the sharp emission of catecholamines leads to spasms and is the result of the difficulty of blood flow.Blood becomes thicker, the process of biological novels is complicated.
Nicotine negatively affects the supply of internal organs with oxygen.Oxygen starvation arises as a result leading to good decline.
Blood test in general
Smoking affects blood tests in general, so it is possible to determine the development of inflammation or infection.Due to the reaction between hemoglobin and carbon monoxide, in high concentrations of cigarette smoke, carboxghemoglobin is formed.
This substance, unlike protein, does not transport oxygen to tissues and organs.Hypoxia causes excessive production of lymphocytes and their increased blood content can be considered as the presence of an inflammatory process in the body.Therefore, the results of general blood tests, given immediately after smoking, will not be accurate.
Attention!The maximum nicotine concentration in the blood reaches about half an hour after smoking, so before you donate blood from your fingers, you should not smoke at least 1-1.5 hours, but it is better to increase this time.
Biochemical analysis
A biochemical test allows you to identify many internal diseases, including the presence of cancer and the diseases of the cardiovascular system.That is why it is very important to carefully prepare for research, observing all rules, including smoking before donating blood.
Venous blood is the most information material, thanks to the study, you can get a fairly full idea about the body's condition.But for this, the analysis results must correspond to the real situation.
In the process of using tobacco products in the blood, not only the distribution of certain substances occurs.Smokers change lipid-carbohydrate metabolism, which also affects blood indicators.Therefore, experts spoke out before letting blood from the veins quite classified.The abstinence should be a few hours.
Road analysis
Sugar analysis helps detect a serious disease like diabetes.The answer to the question, you can smoke before donating blood for sugar, which 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 inaccurate explanation of the results.
If the patient has an increased sugar level, even a cigarette smoking can significantly deteriorate the situation.
Blood on HIV
When donating blood for HIV infection, it is banned from smoking.You need to quit smoking 2-3 hours before the procedure.Nicotine and other substances in cigarette smoke inhibit the immune system.Because of this, the results of HIV analysis may not be accurate and does not display the true condition of the patient.
Hormone research
The context of hormones is a very important indicator that affects the condition and performance of the entire organism.Nicotine affects adrenal glands, leading to hormonal synthesis, especially cortisol.In addition, smokers reduce the production of testosterone and in estrogen and prolactin women.
Smoking before analysis of hormones can negatively affect the activity of the thyroid.Therefore, the desire to give up a cigarette for a few hours before leaps of blood.
How to raise influence?
Nicotine causes changes in blood structure at cell level, and also affects plasma.A person who decided to donate blood to help others undergo a mandatory exam.If the result is satisfactory, you can become a sponsor.
Because donated blood can be used in a series of situations in which life and death problems are sometimes solved, its quality must be perfect.Therefore, by guiding the sponsor in the future, the doctor details all the ban and limitations available.Including it published in the time before the procedure, it is necessary to refuse alcohol (2-3 days) and cigarettes (at least 1 hour).
In the blood of an enthusiastic smoker, nicotine and other harmful substances received during the smoking process constantly present, because a smoker with frequency that simple blood does not have time to clean.Such people may not be allowed to donate at the selection stage.
How to prepare a smoker to test blood?
Before donating blood for analysis, you can not only smoke.In order for the research results to be completely reliable and come up with a true idea of the patient's health status, some preparation rules must be followed.They are as follows:
- Blood for research was given in the morning (from 8.00 to 11.00).This is due to the fact that the indicators are in the day and indicators obtained from the morning fence of biological materials used as average data.
- Blood is recommended to use hungry stomach, and the breakdown between the surrender of biological materials and the last meal can be from 8 to 14 hours.This item is due to the fact that the food that enters the body affects both blood and hormone levels.
- From smoking before analysis, people should also restrain.You can smoke a cigarette at least an hour before donating blood.But for some studies, the period of abstinence increased.
- To avoid strong emotional shocks and physical activity, as they can affect biochemical indicators and hormone levels.
- Be sure to warn your doctor about medications.Perhaps, to analyze, they will have to refuse for a while.
You should know, not only because you should not suck much blood before blood, but also for time to restrain alcohol.For different studies, doctors call different terms, but at least - a day.
Habits and urine analysis
Regarding whether or not to smoke before analysis of urine or not, the opinions of doctors mainly converge.Most experts do not recommend using tobacco products before using urin.This is due to the fact that the chemicals in cigarettes affect the composition of the urine and may deform the results obtained in the study.
The disagreements that arise in time will pass after a cigarette smoking until providing biological liquids.The main amount of nicotine and other harmful substances begins to be filtered by the kidneys and settles into the urine for about 8 hours after entering the body.But tobacco began its effect on the body almost immediately.
Tobacco ingredients, into the body, affecting hormones, liver and other internal organs.Therefore, it should not be smoked at least one hour before analysis, but it is better to restrain for 10-12 hours.
Conclusion
The data obtained as the result of the analysis may not be accurate because a recent cigarette smoked.This will lead to an inaccurate diagnosis and accordingly, the prescription treatment is incorrect.But arguing that smoking often negatively affects the health and condition of the body, poor test results can reflect the real picture and point out the existing diseases.
