Depends on your country and age.
Blood alcohol concentration is measured by means of blood tests. It is estimated by means os alcohol breath machines.
The maximum BAC (blood-alcohol content) you are legally allowed to have before being considered illegal is 0.08% in the US. In the UK the limit is 35 micrograms of alcohol in 100 milliliters of breath.
no the higher the content the higher the number ..breath or blood
Blood alcohol content of .08 is legally drunk in all states.
Blood Alcohol Content BAC 0.10.
Only a blood test can measure BAC. A breath tester can only ESTIMATE the BAC.
Alcohol in a person's bloodstream passes through the lungs into a person's breath and can be detected using this test. It is very hard to fool! It depends on the device. Brethalyzers measure electricity created by the presence of alcohol, while blood work uses laboratory testing procedures. During respiration, blood in the lungs gets vaporized. It's the breath with the vaporized blood that gets measured for alcohol content.
No. Breathalyzers are instruments that are utilized in a number of professions to determine the amount of blood alcohol content by analyzing a breath sample obtained from an individual. The breathalyzer works on the principle of estimating the blood alcohol content of an individual based on a sample of breath that is obtained from the suspect.
When you drink, you exhale a certain amount of the alcohol in your breath. This is how blood alcohol content (BAC) is measured by breathalyzers. You blow into the machine, if analyzes how much alcohol is in your breath, performs a mathematical equation, and determines how much alcohol is in your bloodstream.
Blood alcohol content. It is used to find out what level of alcohol is in someone's system.
Breath alcohol level refers to the amount of alcohol vapor in the breath. Alcohol is excreted into the lungs from the blood in a fixed proportion to the amount in the blood. Therefore, measuring breath alcohol gives an indirect, but accurate, measurement of the amount of alcohol in the blood, and the degree of impairment to brain function.
