Which antiseptic should you use when drawing blood for an alcohol test?

When drawing blood for an alcohol test, it's important to avoid using alcohol-based antiseptics, as they can contaminate the sample and affect the results. Instead, a non-alcohol antiseptic, such as chlorhexidine or iodine-based solutions, should be used to cleanse the skin prior to the blood draw. This helps ensure that the test results accurately reflect the individual's blood alcohol concentration. Always follow specific protocols and guidelines set by your laboratory or institution.
