You never should use an alcohol swab for a DWI blood draw. If you are testing for alcohol you don’t want to contaminate the needle with outside alcohol. It’s proper to use an alternative such as a Povidone Iodine prep pad or Betadine. Alcohol only takes a few seconds to cleanse the venipuncture site while Betadine and Iodine take up to 2 minutes. The problem is that the blood drawer never waits long enough for Betadine to dry and to do its job properly. This causes the needle to come into contact with bacteria on the skin which contaminates the blood sample.
