Know Everything About Blood Alcohol Level

A blood alcohol test is a type of test that assesses the level of alcohol in your bloodstream. These days, people are accustomed to the breathalyzer test. This test is performed by police officers on suspects of drunk driving. Though a breathalyzer gives quicker results, still, it is not as accurate as measuring the blood alcohol level in your bloodstream.

The cost of the blood alcohol test is Rs.600 to Rs.800, depending on your location and place.

Alcohol or ethanol is the prime ingredient for alcoholic beverages such as beer, wine, and liquor. If you consume an alcoholic drink, it will be absorbed into your bloodstream and processed by the liver. Your liver is able to process one drink an hour. One drink is usually defined as 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of whiskey.

But if you drink faster than your liver can process the alcohol, then you may experience drunkenness or intoxication. Intoxication may also lead to some behavioral changes and impaired judgment. The effects of alcohol are not the same for all. It depends on a plethora of factors such as age, weight, gender, and what food you have consumed before drinking.

The Purpose of this Test

This Test is Beneficial in the Following Ways

In the United States, 0.08 percent blood alcohol level is allowed for drivers who are above 21 years. Drivers younger than 21, are not permitted to consume alcohol when driving.

2. Are Legally Drunk

The legal alcohol limit for drinking in public places may vary from country to country.

3. A person is Drinking while in a Treatment Program that Prohibits Drinking

If you are suffering from alcohol poisoning, then your blood alcohol level gets very high. Alcohol poisoning may adversely affect various functions of your body including breathing, heart rate, and temperature.

Teens and adults are more susceptible to binge drinking. Binge drinking is another cause of alcohol poisoning. Binge drinking uplifts the level of blood alcohol within a short period. Binge drinking is considered four drinks for women and five drinks for men in two hours.

 Young children may also consume alcohol from various household products that come up with alcohol, such as mouthwash, hand sanitizer, and certain cold medicines.
