How reliable is a blood alcohol test?

On Behalf of | Nov 25, 2019 | DUI |

When Georgia residents get pulled over and are suspected of driving under the influence, it’s likely that a series of tests will follow that may be used to determine if you are under the influence or not. However, it should be noted that even the most reliable of these tests have their weak points.

The most reliable among all tests used to check for blood alcohol content level are the tests that require you to have blood drawn. Your blood is tested directly in a lab, which then reads how much alcohol is present. However, even with this method there can be errors.

For one, human error is always a possibility no matter what. Medical labs are often swamped and it isn’t unheard of for samples to get swapped around accidentally. Not only that, but sometimes a blood sample may be left out for too long. If given the chance to coagulate or begin to deteriorate, the reading may come out as a false positive for a high blood alcohol content level.

Additionally, there is a slight issue with this method of measurement as it allows more time for alcohol to seep into the blood between arresting you and taking your blood to test. It’s possible that while you were driving, your blood alcohol content level was actually lower than the testing shows.
