Does Alcohol Show Up in Bloodwork?

Alcohol Show Up in Bloodwork

Are you wary of how your alcohol consumption will show up in your blood work? Interestingly, there may be some hidden aspects. The research studies uncovered that several metabolic processes work together to eliminate alcoholic beverages from the body.

Regular blood work cannot determine the presence of alcohol in your body. With boosted technological advancements, medical science can detect alcohol in your blood because the legal max permissible blood alcohol content limit is .08%. Read on to be above board on it with credible insights. 

How Is Alcohol Detectable In Your Body? 

Generally, an alcohol blood examination determines the concentration of alcohol, its biomarkers, or its metabolites in the blood or serum. However, many significant blood tests are used for detecting alcohol levels in your body. Likewise, other body saps, such as sweat, hair, urine, breath, and saliva, detect alcohol. 

Typically, the fermentation of sugars, carbohydrates, and yeast produces alcohol. Beer, wine, and other alcoholic beverages contain an intoxicating content called ethanol. However, blood tests can detect significant drinking, but only within specific time windows. 

How Does Alcohol Behave In Your Body? 

Does alcohol remain in your system for a long time? Well, it depends on how much alcohol you consume daily. After drinking alcohol, it’s gripped into the digestive system. At first, it reaches the stomach and then into the small intestine. Your stomach absorbs a small amount of alcohol, while the small intestine absorbs its remaining amount. From there, it enters your central bloodstream. 

The liver is responsible for processing ingested alcoholic beverages. If you consume more alcohol, it builds up in the blood and other tissues until it’s digested. Alcohol effects take 15 to 45 minutes to kick in from the body of a healthy person. Low alcohol tolerance shows signs of intoxication with even 0.05% of blood alcohol. 

Leading Factors Affecting Your Blood Alcohol

Many factors can alter your blood alcohol content in several ways. 


Consuming alcohol before a meal can significantly slow the pace at which the body absorbs it. Food slows the work of the stomach in digestion. As a result, food slows the absorption of alcohol in the small intestine. An empty stomach can increase alcohol levels by as much as three times compared to someone who eats before drinking.

Consuming food at regular intervals while drinking can stimulate enzyme activity in the liver, reducing the body’s absorption of alcohol.


It’s pretty much common that sometimes drug interactions directly impact your body’s capacity to metabolize alcohol. These specific drugs reduce the rate at which the stomach empties into the small intestine and liver. They also increase the rate of alcohol absorption.

In particular, the medicines that interact with alcohol are cough suppressants, ADHD drugs, and diabetes medications. 


The span of intoxication and the danger of liver damage increase with age because alcohol remains in the liver for a longer period before entering the bloodstream. A greater BAC can distinguish that the body’s water content has increased.

Medicines are also more common among older people, which can adversely affect the liver. That’s why these age factors work together to slow down the metabolization pace of alcohol in the body.

Body Size

Your body size can also influence your alcohol metabolization rate. More body fat means less water in the tissues to absorb alcohol. Hence, if you have a higher body fat ratio, you may have an increased blood alcohol concentration.

So, in reality, a more muscular person will have a higher alcohol level than a taller & thin person of the same weight. 


Alcohol is processed differently by women than men, and its effects will be felt more in a woman’s system. The main motive for this difference is women’s higher fat ratio than their body water.

Therefore, if two people, a man and a woman of equal height and weight, drink the same alcohol, the man will dilute it more than the woman’s partner. Additionally, drinking during menstruation increases a woman’s blood alcohol concentration because of fluctuations in hormone levels. 

Do You Know What Is Auto Brewery Syndrome?

Auto brewery syndrome is a sporadic situation. In auto-brewery syndrome, excessive ethanol is produced by yeast in the digestive tract. People with auto-brewery syndrome have blood alcohol levels despite abstaining from alcoholic beverages. Auto-brewery syndrome is a metabolic disorder in which the body automatically transforms the carbohydrates consumed by the patient into ethanol or alcohol. 

According to research studies, symptoms of an auto-brewery syndrome are similar to alcohol intoxication. It includes stumbling and slurred speech, stomach pain, etc. So, it is essential to check out all other causes before diagnosing because the symptoms are not so specific.

What You Should Know About Your Blood Alcohol 

Here are some common motives for your alcohol blood testing: 

For Addiction Surveillance

Some methods of treating alcohol use disorder or alcoholism include testing for alcohol consumption. Medical personnel can learn if their patient continues drinking alcohol by conducting tests.

For Workplace Safety & Security

The law does not refuse pre-employment or post-accident testing of employees for alcohol consumption. Government agencies like the Department of Defence and the Department of Transportation conduct random drug and alcohol testing to ensure the safety and security of their personnel. 

For Medical Diagnostic Tests

Blood alcohol testing is crucial in diagnosing alcohol poisoning. It’s a potentially fatal condition brought on by excessive alcohol use. 

For Legal Procedures

You may need a blood alcohol test as admissible evidence in a court of law. It may be used in an inquiry or further prosecution. The BAC test can be used to detect drunk driving, detect underage drinking, and keep tabs on parolees’ drinking habits.

Final Verdict 

So, no need to be doubtful in this matter anymore. Alcohol appears in your blood work whether you consume a moderate quantity. Modern scientific procedures can detect the presence of alcohol in the bloodstream within minutes, even after your first drink.

You may face several situations in which a blood alcohol test would be necessary. For instance, it includes drug testing in the workplace and checking whether or not a driver is impaired. That’s why for the best concern of your health, you must keep your alcohol levels under control.
