Blood is always more accurate as it is a direct test - breath is indirect.
No, blood alcohol level and breath alcohol level are not the same. Blood alcohol level is a direct measurement of the amount of alcohol in the blood, while breath alcohol level is an indirect measurement based on the amount of alcohol in the breath, which is correlated with blood alcohol level.
Only a blood test can measure BAC. A breath tester can only ESTIMATE the BAC.
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.
A blood test is the only way to measure blood alcohol concentration accurately. Alcohol breath testers (Breathylizer, etc.) actually only estimate the blood alcohol concentration.
If you breath or have a blood alcohol level of .08 your license will be suspended.
Yes, ethanol can affect a breath test by causing a higher reading due to its presence in the breath. Breath tests are designed to measure the amount of alcohol in the breath, which correlates to blood alcohol concentration. Ethanol in the breath can lead to a false positive result on a breath test.
Research indicates that breath tests can vary at least fifteen percent from actual blood alcohol concentration. The alcohol breath test may be higher than their true blood alcohol. These reading can be used in court as evidence.
You can choose a breath test or a blood test.
Alcohol will show up on your breath your attitude and in your blood if they take it
No, but it could elevate your chances of death
Absorption through the skin is extremely limited, although it could add to the blood alcohol content. It would still be detected by the Breathalyzer because it measures alcohol leaving the bloodstream in the lungs.
No, a breath test can not be beat. The breath tests measures the alcohol content in a persons body.
