The list of diagnostic tests must include blood tests.In order to obtain the most accurate results, the influence of some third-party factors needs to be eliminated.We will talk specifically about alcohol.Patients are always asked not to drink alcohol during the first 2 days before the examination.
But does alcohol actually affect blood tests?Of course you can, the specific methods are as follows:
- Reduced number of red blood cells and hemoglobin;
- Reduce urea dosage;
- Reduce lactate and glucose levels;
- Increases triacylglycerol levels.
Ethanol thickens the blood and promotes the formation of blood clots.High hemoglobin and red blood cell levels may be mistaken for symptoms of megaloblastic anemia.
Alcohol has the greatest impact on biochemical profile blood tests.Wrong conclusions may be drawn due to low uric acid, as this is a classic symptom of poor circulation.High concentrations of triacylglycerols are a classic symptom of ischemic heart disease and viral hepatitis.To prevent mistakes like this from happening, you should tell your doctor in advance about the alcohol you take if this happens.
In addition to ethanol itself distorting blood parameters, it can sometimes damage laboratory equipment.Therefore, when it interacts with the reagent, the latter stops reacting with glucose.Enzyme tests can show errors even when small amounts of ethanol are present in the blood.
How does alcohol affect your bottom line?
In addition to alcohol, smoking and some harmful foods can also negatively affect blood test results.But the last factor is the most important and must be eliminated.Post-alcohol tests are meaningless because they are inaccurate.
General analysis
How blood parameters are distorted under the influence of ethanol:
- Increased cholesterol levels;
- Red blood cells are destroyed;
- Decreased hemoglobin.
If you drink at least a little before a typical blood draw, the number of red blood cells - which contain hemoglobin - will certainly decrease.They are involved in the circulation of oxygen to all internal organs and tissues and then back to the lungs.
Ethanol has a destructive effect on the membranes of red blood cells, as a result, their motor activity is disrupted - they stick together, since they no longer repel each other.As a result, their number decreases and hemoglobin levels decrease.Against this background, thrombi form and microcirculation slows down.
Since under the influence of alcohol the blood thickens and becomes filled with a flocculent structure, its flow through capillaries and vascular spaces is hindered.Not only does this hinder accurate research, but it also threatens human health.The only thing that will show up is alcohol poisoning in the body if you drink alcohol within 10-12 hours before the test.
Biochemical analysis
On top of that, ethanol can skew the results of biochemical blood tests, which are designed to provide a more detailed clinical picture.With its help, they can find out which components are missing and which ones are too many and need to be reduced.
How alcohol affects such tests:
- lower blood sugar levels;
- Increase uric acid;
- disrupts oxygen supply to cells;
- Deteriorating a person's overall condition.
Low blood sugar levels may indicate diabetes, while excess urea is a result of drinking alcoholic beverages.But the latter indicator can be a sign of serious circulatory disease as well as hemorrhagic stroke or left ventricular disease.Too much urea is also a symptom of gout or chronic arthritis.That's why it's so important not to drink alcohol before an exam.
Failure to follow the rules of preparation before a blood test, even with any alcohol-containing product, will often result in inaccurate results.Excess triacylglycerols may be present.These neutral fatty compounds are important for identifying many diseases in the body: ischemia, atherosclerosis, viral hepatitis, cerebrovascular thrombosis.
Even during laboratory tests, doctors do not use products containing alcohol.Although some believe that infections can be detected more effectively with their help.But since even small amounts of ethanol can significantly distort the data, this option was ruled out.
Indeed, in practice, patients often conceal the fact that they previously drank alcohol from their doctors.This behavior results in unreliable diagnosis, so serious lesions may not be seen and opportunities may be missed.Also, people who are hungover may feel unwell when they come to donate blood.possible:
- faint;
- Dizziness;
- Migraine;
- Nausea and vomiting.
By donating blood while awake, a person's condition will not worsen in any way because the loss is negligible.But after drinking alcohol, metabolic processes and brain circulation are disrupted.The patient's brain is then starved of oxygen, causing loss of consciousness and dizziness.Even after donating blood, a person may continue to experience headaches for a long time.
Additionally, during a hangover, the olfactory reflex is particularly sensitive to a variety of specific odors.In cases of indigestion, even the smell of bleach or alcohol in the doctor's office can trigger the gag reflex.
Draw blood to test sugar
If a metabolic disorder is suspected, a blood glucose test is performed.Collection is done by finger prick.Drinking alcohol the day before can thicken your blood, making it difficult to draw blood.
Ethanol is known to have adverse effects on liver function.Even the reagents and laboratory equipment used in the work can react to it and give erroneous results.Therefore, when examining blood containing products of the breakdown of alcohol, contradictory indicators may appear: decreased or increased glucose values.
One gram of ethanol adds 6-7 kcal.With the help of liver enzymes, they are converted into sugar.That's why its levels increase dramatically.But blood sugar drops are also possible.In just a few hours each day, its levels are stabilized by carbohydrates in the digestive tract.The rest of the time, the liver uses strategic reserves to actively synthesize glucose.But alcohol hinders this process, causing blood sugar levels to drop.
After two days of drinking alcoholic beverages, glucose begins to be produced as before.
This indicator is also evidence of possible diabetes, but doctors would assume that it is a result of the effects of ethanol.Therefore, you may waste time by not starting treatment on time.
When is the right time to drink?
Any alcoholic beverage, even beer, can affect the results of almost any type of test.Drinking alcohol is specifically prohibited before undergoing the prescribed examinations before surgery.In some cases, small amounts of alcohol are not prohibited.Doctors tell patients in advance what the odds are.
Generally, alcohol is prohibited 1.5-2 days before venous blood collection.This is enough time to stop any process that is having a significant impact on the body.
For ELISA testing (for HIV, hepatitis and other sexually transmitted infections), alcohol abstinence is mandatory for at least 3 days and up to 7 days in individual cases.Otherwise, the accuracy of the results cannot be guaranteed.If the doctor discovers that the patient is not adhering to this rule, the surgery is postponed until the moment the body has completely eliminated the toxins.
Drinking alcohol before a breathalyzer test and ignoring medical advice can make diagnosis very complicated.Increased risk of receiving erroneous results.In addition to alcoholic products, you should also exclude fatty foods from your diet and smoke less and stay nervous.Under their influence, hormone levels in the blood rise sharply.They make detecting the virus difficult.Incorrect data may mislead the doctor and he may incorrectly diagnose any serious pathology (e.g. tumors, hepatitis).
There is no prohibition against drinking alcohol before taking a blood test on the driver to determine the degree of intoxication.This diagnosis is made without warning.In all other cases, drink only clean water and in small amounts.
Therefore, ethanol greatly affects the accuracy of blood test results and can differ significantly from normal results.This is affected by the amount of ethanol breakdown products, the type of procedure and the accuracy of its implementation.Incorrect diagnosis leads to incorrect diagnosis, which leads to unnecessary or delayed treatment.
