All about Blood Alcohol Testing

The blood alcohol test measures the amount of alcohol that is present in the blood at the time a blood sample is taken. Consequently, the test does not determine how long the individual has been drinking and does not necessarily show whether the person has a drinking problem or not. Since a few medicines can alter the blood test results, people undergoing an alcohol blood test need to inform the doctor, the agency or the person administering the test about all the prescription or non-prescription medicines he has been taking recently. In addition to that, people taking medicines for blood-thinning or has clotting or bleeding problems, then he or she has to inform the individual or entity taking the blood sample about their problems before the blood sample is taken.

The Blood Alcohol Testing is one of the most accurate methods for testing the amount of alcohol in a person's blood. But they are also one of the most expensive methods of testing a person's blood alcohol content. Owing to their high cost and intrusiveness, this method is the least common method for testing alcohol in a person's blood.
