The blood alcohol level (TAS) is the measure of the amount of alcohol present in the blood, based on the volume of alcohol consumed over a given period of time.

While some may choose to count drinks or use calculators to guess your BAC, you should be aware that a substantial number of variables influence it, making this method of estimating BAC not only erroneous, but downright dangerous.

The test with the BACtrack is certainly the most reliable method of estimating your TAS, especially in light of the wide variety of factors that influence it, they are:

Age - As you get older, the intoxicating effects of alcohol become more and more pronounced.

Gender - Alcohol is highly soluble in water. As women generally have a lower water content in their body than men, and therefore usually achieve a higher BAC if they consume alcohol at a similar rate as their male counterparts, even if they are the same age and weight. Women also have a lower amount of enzyme in their stomach that breaks down alcohol less than men.

Consumption Rate - The faster you consume alcohol, the faster your BAC will increase.

Drinking power - The more alcohol a drink contains, the more it will end up in your bloodstream.

Body Type - The more you weigh, the more water you have in your body, which has a diluting effect on the alcohol you consume. That's why bigger people usually need more drinks to "keep up" with their smaller companions.

Fat/muscle content - Adipose tissue has a low water content and cannot absorb alcohol, and alcohol must remain in the bloodstream until the liver can break it down. However, tissues with higher water content, such as muscles, do absorb alcohol. Thus, BAC will normally be higher in the person with more body fat.

Metabolism - "Metabolic tolerance" varies from person to person and describes the rate at which alcohol is processed by the body.

Emotional State - Stress can cause the body to divert blood from the stomach and small intestine to the muscles, and slow the rate at which alcohol is absorbed into the bloodstream. When you calm down and your blood flows normally again, you may experience an increase in your BAC.

Medicines - Many medications react negatively with alcohol, including cold or allergy pills and prescription drugs. They can intensify the effects of alcohol and even endanger your health. If you are taking medication, check product labels for warnings about alcohol, or consult your doctor or pharmacist before drinking.

Food - If you drink alcohol on an empty stomach, your BAC will be higher than a person who has eaten before drinking. Food delays absorption into your bloodstream, keeping the alcohol you consume in your stomach for a longer period of time.

Carbonation - Carbonated drinks, such as sparkling wine or champagne, or mixed drinks with soft drinks can increase the rate at which alcohol passes through your stomach and result in a higher BAC.

Diabetes - Alcohol can affect glucose levels in people with diabetes and cause hypoglycaemia. Diabetics should consult their doctors about alcohol consumption and avoid drinking on an empty stomach.

Alcohol intolerance - Alcohol can cause adverse reactions in some, including flushing of the skin, nasal congestion, elevated heart rate, and reduced blood pressure. According to the Mayo Clinic, alcohol intolerance is caused by a "genetic condition in which the body is unable to break down alcohol.

With all these factors influencing its TASYou should never rely on counting drinks or using a calculator to make an important decision.

The equipment BACtrack outweigh all of these factors. By using your breath, it can accurately estimate your blood alcohol level and tell you where you stand safely.

Ensure your safety on your way home now.
