If you are charged with an OWI, before evidence is presented in court, how does the Wisconsin State Laboratory of Hygiene measure your blood sample? Once your sample lands in the Wisconsin forensic lab, your blood sample will be analyzed using a chromatograph. Your blood alcohol content will be reported in units of grams per 100 milliliters of whole blood.
However, the results from this testing can often prove inaccurate. It is important to seek the aid of an experienced criminal defense attorney, who can challenge the results of blood, breath or urine tests in an OWI case.
